Commentary on Mark 16 verses 14–18
Here is, I. The conviction which Christ gave his apostles of the truth of his resurrection (Mar 16:14); He appeared to them himself, when they were all together, as they sat at meat, which gave him an opportunity to eat and drink with them, for their full satisfaction; see Act 10:41. And still, when he appeared to them, he upbraided them with their unbelief and hardness of heart, for even at the general meeting in Galilee, some doubted, as we find Mat 28:17. Note, The evidences of the truth of the gospel are so full, that those who receive it not, may justly be upbraided with their unbelief; and it is owing not to any weakness or deficiency in the proofs, but to the hardness of their heart, its senselessness and stupidity. Though they had not till now seen him themselves, they are justly blamed because they believed not them who had seen him after he was risen; and perhaps it was owing in part to the pride of their hearts, that they did not; for they thought, "If indeed he be risen, to whom should he delight to do the honour of showing himself but to us?" And if he pass them by, and show himself to others first, they cannot believe it is he. Thus many disbelieve the doctrine of Christ, because they think it below them to give credit to such as he had chosen to be the witnesses and publishers of it. Observe, It will not suffice for an excuse of our infidelity in the great day, to say, "We did not see him after he was risen," for we ought to have believed the testimony of those who did see him.
II. The commission which he gave them to set up his kingdom among men by the preaching of his gospel, the glad tidings of reconciliation to God through a Mediator. Now observe,
1.To whom they were to preach the gospel. Hitherto they had been sent only to the lost sheep of the house of Israel, and were forbidden to go into the way of the Gentiles, or into any city of the Samaritans; but now their commission is enlarged, and they are authorized to go into all the world, into all parts of the world, the habitable world, and to preach the gospel of Christ to every creature, to the Gentiles as well as to the Jews; to every human creature that is capable of receiving it. "Inform them concerning Christ, the history of his life, and death, and resurrection; instruct them in the meaning and intention of these, and of the advantages which the children of men have, or may have, hereby; and invite them, without exception, to come and share in them. This is gospel. Let this be preached in all places, to all persons." These eleven men could not themselves preach it to all the world, much less to every creature in it; but they and the other disciples, seventy in number, with those who should afterward to be added to them, must disperse themselves several ways, and, wherever they went, carry the gospel along with them. They must send others to those places whither they could not go themselves, and, in short, make it the business of their lives to send those glad tidings up and down the world with all possible fidelity and care, not as an amusement or entertainment, but as a solemn message from God to men, and an appointed means of making men happy. "Tell as many as you can, and bid them tell others; it is a message of universal concern, and therefore, ought to have a universal welcome, because it gives a universal welcome."
2.What is the summary of the gospel they are to preach (Mar 16:16); "Set before the world life and death, good and evil. Tell the children of men that they are all in a state of misery and danger, condemned by their prince, and conquered and enslaved by their enemies." This is supposed in their being saved, which they would not need to be if they were not lost. "Now go and tell them," (1.) "That if they believe the gospel, and give up themselves to be Christ's disciples; if they renounce the devil, the world, and the flesh, and be devoted to Christ as their prophet, priest, and king, and to God in Christ a their God in covenant, and evidence by their constant adherence to this covenant their sincerity herein, they shall be saved from the guilt and power of sin, it shall not rule them, it shall not ruin them. He that is a true Christian, shall be saved through Christ." Baptism was appointed to be the inaugurating rite, by which those that embraced Christ owned him; but it is here put rather for the thing signified than for the sign, for Simon Magus believed and was baptized, yet was not saved, Act 8:13. Believing with the heart, and confessing with the mouth the Lord Jesus (Rom 10:9), seems to be much the same with this here. Or thus, We must assent to gospel-truths, and consent to gospel-terms. (2.) "If they believe not, if they receive not the record God gives concerning his Son, they cannot expect any other way of salvation, but must inevitably perish; they shall be damned, by the sentence of a despised gospel, added to that of a broken law." And even this is gospel, it is good news, that nothing else but unbelief shall damn men, which is a sin against the remedy. Dr. Whitby here observes, that they who hence infer "that the infant seed of believers are not capable of baptism, because they cannot believe, must hence also infer that they cannot be saved; faith being here more expressly required to salvation than to baptism. And that in the latter clause baptism is omitted, because it is not simply the want of baptism, but the contemptuous neglect of it, which makes men guilty of damnation, otherwise infants might be damned for the mistakes or profaneness of their parents."
3.What power they should be endowed with, for the confirmation of the doctrine they were to preach (Mar 16:17); These signs shall follow them that believe. Not that all who believe, shall be able to produce these signs, but some, even as many as were employed in propagating the faith, and bringing others to it; for signs are intended for them that believe not; see Co1 14:22. It added much to the glory and evidence of the gospel, that the preachers not only wrought miracles themselves, but conferred upon others a power to work miracles, which power followed some of them that believed, wherever they went to preach. They shall do wonders in Christ's name, the same name into which they were baptized, in the virtue of power derived from him, and fetched in by prayer. Some particular signs are mentioned; (1.) They shall cast out devils; this power was more common among Christians than any other, and lasted longer, as appears by the testimonies of Justin Martyr, Origen, Irenaeus, Tertullian Minutius Felix, and others, cited by Grotius on this place. (2.) They shall speak with new tongues, which they had never learned, or been acquainted with; and this was both a miracle (a miracle upon the mind), for the confirming of the truth of the gospel, and a means of spreading the gospel among those nations that had not heard it. It saved the preachers a vast labour in learning the languages; and, no doubt, they who by miracle were made masters of languages, were complete masters of them and of all their native elegancies, which were proper both to instruct and affect, which would very much recommend them and their preaching. (3.) They shall take up serpents. This was fulfilled in Paul, who was not hurt by the viper that fastened on his hand, which was acknowledged a great miracle by the barbarous people, Act 28:5, Act 28:6. They shall be kept unhurt by that generation of vipers among whom they live, and by the malice of the old serpent. (4.) If they be compelled by their persecutors to drink any deadly poisonous thing, it shall not hurt them: of which very thing some instances are found in ecclesiastical history. (5.) They shall not only be preserved from hurt themselves, but they shall be enabled to do good to others; They shall lay hands on the sick, and they shall recover, as multitudes had done by their master's healing touch. Many of the elders of the church had this power, as appears by Jam 5:14, where, as an instituted sign of this miraculous healing, they are said to anoint the sick with oil in the name of the Lord. With what assurance of success might they go about executing their commission, when they had such credentials as these to produce!
But in a mystic sense we may understand that faith here labours, leading the active life, but there it reigns secure in the contemplative vision. Here we see His face through a glass, there we shall see the truth face to face, wherefore He was shown to them as they were walking, that is, labouring, in another form. And when it was told, the disciples did not believe, because they saw, like Moses, that which was not enough for them, for he said, show me thyself; (Exod. 33:18. Sept.) forgetting his flesh, he prays in this life for that which we hope for in the life to come.
But He appeared when all the eleven were together, that all might be witnesses, and relate to all men what they had seen and heard in common. It goes on: And upbraided them with their unbelief and hardness of heart, because they believed not them who had seen him after his resurrection.
But He rebukes their want of faith, that faith might take its place; He rebukes the hardness of their stony heart, that the fleshy heart, full of love, might take its place.
We have faith for a defence, if we are not smitten with distrust itself also, in immediately making the sign and adjuring, and besmearing the heel with the beast.
For what else are hearing, reading and copiously depositing things in the memory, than several stages of drinking in thoughts? The Lord, however, foretold concerning his faithful followers, that even “if they should drink any deadly thing, it will not hurt them.” And thus it happens that they who read with judgment, and bestow their approval on whatever is commendable according to the rule of faith, and disapprove of things which ought to be repudiated, even if they commit to their memory heretical statements which are declared to be worthy of disapproval, they receive no harm from the poisonous and depraved nature of these sentences.
They who by their good exhortations take away malice from the hearts of others, take up serpents. And when they hear pestilent persuasions, yet are not drawn thereby to evil works, they drink indeed what is deadly, but it shall not hurt them. They who, as often as they see their neighbors grow weak in good works, run to help them with all their strength, and by the example of their own deeds strengthen the lives of those who waver in their own actions; what else do they do but lay hands on the sick that they may recover?
Which miracles are so much the greater as they are spiritual; so much the greater as by them not bodies but souls are raised to life. These signs therefore, dearest brethren, you can do by God's help if you will. For by those outward signs, life cannot be obtained by those who work them. For those bodily miracles sometimes show holiness, but do not make it; but these spiritual ones, which are wrought in the mind, do not show but make the virtue of life. The evil can have those, but only the good can enjoy these.
Whence the Truth says of certain ones: Many will say to me in that day: Lord, Lord, have we not prophesied in your name, and in your name cast out devils, and in your name done many mighty works? And then I will confess to them: I never knew you; depart from me, you workers of iniquity. Do not therefore, dearest brethren, love signs which may be had in common with the reprobate; but love these miracles of charity and piety which we have spoken of, which are so much the safer as they are hidden, and for which the recompense with the Lord is so much the greater as the glory among men is less.
(ubi sup.) We should observe that Luke says in the Acts, As he was eating with them he commanded that they should not depart from Jerusalem, and shortly afterwards, while they beheld he was taken up. For He ate, and then ascended, that by the act of eating, the truth of the flesh might be declared; wherefore it is also here said, that he appeared to them for the last time as they sat at meat.
(ubi sup.) Another reason also why our Lord rebuked His disciples, when He left them as to His bodily presence, was, that the words which He spoke on leaving them might remain more deeply impressed upon the hearts of His hearers.
(ubi sup.) After rebuking the hardness of their hearts, let us hear the words of advice which He speaks. For it goes on: Go ye into all the world, and preach the Gospel to every creature. Every man must be understood by every creature; for man partakes something of every creature; he has existence as have stones, life as trees, feeling as animals, understanding as have Angels. For the Gospel is preached to every creature, because he is taught by it, for whose sake all are created, whom all things are in some way like, and from whom therefore they are not alien. By the name of every creature also every nation of the Gentiles may be meant. For it had been said before, Go not into the way of the Gentiles. (Matt. 10:5) But now it is said, Preach the Gospel to every creature, so that the preaching of the Apostles which was thrust aside by Judæa, might be an assistance to us, since Judæa had haughtily rejected it, thus witnessing to her own damnation.
(ubi sup.) But perhaps some one may say in himself, I have already believed, I shall be saved. He says what is true, if he keeps his faith by works; for that is a true faith, which does not contradict by its deeds what it says in words. There follows: But he that believeth not shall be damned.
(ubi sup.) Are we then without faith because we cannot do these signs? Nay, but these things were necessary in the beginning of the Church, for the faith of believers was to be nourished by miracles, that it might increase. Thus we also, when we plant groves, pour water upon them, until we see that they have grown strong in the earth; but when once they have firmly fixed their roots, we leave off irrigating them. These signs and miracles have other things which we ought to consider more minutely. For Holy Church does every day in spirit what then the Apostles did in body; for when her Priests by the grace of exorcism lay their hands on believers, and forbid the evil spirits to dwell in their minds, what do they, but cast out devils? And the faithful who have left earthly words, and whose tongues sound forth the Holy Mysteries, speak a new language; they who by their good warnings take away evil from the hearts of others, take up serpents; and when they are hearing words of pestilent persuasion, without being at all drawn aside to evil doing, they drink a deadly thing, but it will never hurt them; whenever they see their neighbours growing weak in good works, and by their good example strengthen their life, they lay their hands on the sick, that they may recover. And all these miracles are greater in proportion as they are spiritual, and by them souls and not bodies are raised.
(ubi sup.) What shall we say here about infants, who by reason of their age cannot yet believe; for as to older persons there is no question. In the Church then of our Saviour children believe by others, as also they drew from others the sins which are remitted to them in baptism. It goes on: And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; they shall take up serpents.
Or else; to every creature, that is, whether believing or unbelieving. It goes on: He that believeth and is baptized shall be saved. For it is not enough to believe, for he who believeth and is not baptized, but is a catechumen, has not yet attained to perfect salvation.
That is, they shall scatter before them serpents, whether intellectual or sensible, as it is said, Ye shall tread upon serpents and scorpions, which is understood spiritually. But it may also mean sensible serpents, as when Paul received no hurt from the viper. There follows: And if they drink any deadly thing, it shall not hurt them. (Luke 10:19) We read of many such cases in history, for many persons have drank poison unhurt, by guarding themselves with the sign of Christ. It goes on: They shall lay hands on the sick, and they shall recorer.
(non occ.) Mark, when about to finish his Gospel, relates the last appearance of our Lord to His disciples after His resurrection, saying,1 For the last time he appeared unto the eleven as they sat at meat. (Acts 1:4, 9)
That this gift [spiritual healing] was promised to the Church is certain from Scripture. Whether any instance of it is a real instance, or change, or even (as might happen in this wicked world) fraud, is a question only to be decided by the evidence in that particular case. And unless one is a doctor one is not likely to be able to judge the evidence. Very often, I expect, one is not called upon to do so. Anything like a sudden furore about it in one district, especially if accompanied by a public campaign on modern commercial lines, would be to me suspect: but even then I might be wrong. On the whole, my attitude would be that any claim may be true, and that it is not my duty to decide whether it is.

SUMMARY
Mark 16:18, part of the longer ending of Mark's Gospel, presents extraordinary signs that Jesus promises will accompany believers who proclaim the Gospel. These signs include divine protection from physical harm, such as handling serpents or ingesting deadly substances, and the supernatural ability to heal the sick through the laying on of hands. This verse serves as a powerful affirmation of the divine authority and empowerment granted to those commissioned to spread the message of salvation, demonstrating God's active presence and power validating their mission.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Mark 16:18 employs several literary devices to convey its powerful message. The most prominent is Hyperbole, particularly in the promises of handling serpents and drinking deadly things without harm. While these events are presented as literal possibilities (and indeed, there are biblical examples like Paul's experience), their inclusion emphasizes the extraordinary, almost boundless nature of the divine protection promised to believers. This hyperbole serves to underscore the absolute authority and power God grants to His messengers. Symbolism is also at play, especially with "serpents," which can represent not only literal dangers but also the forces of evil and spiritual opposition that believers would encounter in their mission. Overcoming these literal or symbolic threats without harm signifies victory over the powers of darkness. The verse also uses Parallelism in its structure, listing distinct but related miraculous actions (taking up serpents, drinking deadly things, laying hands on the sick) that all point to the same underlying theme of divine empowerment and protection.
THEOLOGICAL AND THEMATIC CONNECTIONS
Mark 16:18, despite its debated textual history, powerfully articulates a core New Testament theological principle: God's active involvement and supernatural empowerment of His people for the advancement of His Kingdom. The signs described are not merely for show, but are intrinsically linked to the proclamation of the Gospel, serving as divine authentication of the message and the messengers. They demonstrate God's sovereignty over creation, evil, and disease, providing comfort and assurance to those undertaking the challenging mission of evangelism. This divine backing underscores the truth that the Gospel is not merely human words but the power of God unto salvation, accompanied by tangible manifestations of His presence.
REFLECTION AND APPLICATION
While the specific literal manifestations of these signs may vary across different eras and contexts, the underlying principles of Mark 16:18 remain profoundly relevant for believers today. This verse calls us to a deep trust in God's sovereign protection and empowering presence as we engage in His work. It reminds us that our mission is not undertaken in our own strength but through the power of the Holy Spirit. We may not literally pick up venomous snakes, but we are called to confront spiritual "serpents"—the deceptive influences, harmful doctrines, and spiritual attacks that oppose the truth of the Gospel. We are to be fearless in the face of "deadly things"—the poisons of cultural compromise, fear, and doubt that threaten to undermine our faith and witness. Moreover, the promise of healing the sick through the laying on of hands encourages us to pray boldly for physical and spiritual restoration, recognizing that God's compassion and power to heal are still active. This passage ultimately inspires boldness in evangelism and confidence in God's supernatural enablement for every aspect of our Christian walk and ministry.
Questions for Reflection
FAQ
Does Mark 16:18 mean Christians should intentionally handle snakes or drink poison to prove their faith?
Answer: No, the verse does not command or encourage believers to intentionally seek out dangerous situations like handling venomous snakes or ingesting poison. Such actions would be a reckless testing of God, which Jesus Himself refused to do when tempted by Satan to jump from the temple (see Matthew 4:7). The context of Mark 16:18 is about divine protection in the course of fulfilling the Great Commission, not about gratuitous displays of power. The example of Paul on Malta illustrates this: he was accidentally bitten by a viper, not intentionally handling it, and God supernaturally protected him. The promise is for preservation from harm, not an invitation to harm.
CHRIST-CENTERED FULFILLMENT
Mark 16:18 finds its ultimate fulfillment and deepest meaning in the person and work of Jesus Christ. The authority and power promised to believers in this verse are not inherent to them but are derivative of Christ's own victory over sin, death, and the powers of darkness. Jesus Himself demonstrated absolute authority over evil spirits (e.g., Mark 1:27), disease (e.g., Mark 2:10-12), and even the forces of nature (e.g., Mark 4:39). He is the one who ultimately "crushed the head of the serpent" (Genesis 3:15), signifying His triumph over Satan and all evil. The ability of believers to "take up serpents" and be unharmed by "deadly things" is a participation in Christ's victory and authority, reflecting His triumph over every spiritual and physical threat. Furthermore, the power to heal the sick is a continuation of Christ's compassionate ministry, as He is the Great Physician who came to bring wholeness and restoration (e.g., Matthew 8:16-17). Thus, Mark 16:18 points to the ongoing work of the ascended Christ through His Spirit in His Church, empowering His followers to carry forward His mission with the same divine authority and compassion that He perfectly embodied, until the day when all things are made new in Him (Revelation 21:5).
