Here is how we know that he remains united with us: by the Spirit whom he gave us.

Matthew Henry
From his Commentary on the Whole Bible. Henry comments on passages, not single verses — this entry covers 1 John 3:23–24. His three-level outline is real structure in the source text, so it is rendered as structure.
The apostle, having mentioned keeping the commandments, and pleasing God, as the qualification of effectual petitioners in and with Heaven, here suitably proceeds,
I.To represent to us what those commandments primarily and summarily are; they are comprehended in this double one:
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment, Jo1 3:23. To believe on the name of his Son Jesus Christ is,
1.To discern what he is, according to his name, to have an intellectual view of his person and office, as the Son of God, and the anointed Saviour of the world. That every one that seeth the Son, and believeth on him, may have everlasting life, Joh 6:40.
2.To approve him in judgment and conscience, in conviction and consciousness of our case, as one wisely and wonderfully prepared and adapted for the whole work of eternal salvation.
3.To consent to him, and acquiesce in him, as our Redeemer and recoverer unto God.
4.To trust to him, and rely upon him, for the full and final discharge of his saving office. Those that know thy name will put their trust in thee, Psa 9:10. I know whom I have believed, and I am persuaded that he is able to keep that which I have committed unto him against that day, Ti2 1:12. This faith is a needful requisite to those who would be prevalent petitioners with God, because it is by the Son that we must come to the Father; through his grace and righteousness our persons must be accepted or ingratiated with the Father (Eph 1:6), through his purchase all our desired blessings must come, and through his intercession our prayers must be heard and answered. This is the first part of the commandment that must be observed by acceptable worshippers; the second is that we love one another, as he gave us commandment, Jo1 3:23. The command of Christ should be continually before our eyes. Christian love must possess our soul when we go to God in prayer. To this end we must remember that our Lord obliges us,
(1.)To forgive those who offend us (Mat 6:14), and,
(2.)To reconcile ourselves to those whom we have offended, Mat 5:23, Mat 5:24. As good-will to men was proclaimed from heaven, so good-will to men, and particularly to the brethren, must be carried in the hearts of those who go to God and heaven.
II.To represent to us the blessedness of obedience to these commands.
The obedient enjoy communion with God: And he that keepeth his commandments, and particularly those of faith and love, dwelleth in him, and he in him, Jo1 3:24. We dwell in God by a happy relation to him, and spiritual union with him, through his Son, and by a holy converse with him; and God dwells in us by his word, and our faith fixed on him, and by the operations of his Spirit. Then there occurs the trial of his divine inhabitation: And hereby we know that he abideth in us, by the Spirit which he hath given us (Jo1 3:24), by the sacred disposition and frame of soul that he hath conferred upon us, which being a spirit of faith in God and Christ, and of love to God and man, appears to be of God.

"And hereby we know that He dwells in us by His Spirit, which He has given us;" that is, by superintendence and foresight of future events.
"And he that doeth His commandment abideth in Him, and He in him. In this we know that He abideth in us, by the Spirit which He hath given us." If in truth thou find that thou hast charity, thou hast the Spirit of God in order to understand: for a very necessary thing it is.
Then if thou wouldest know that thou hast received the Spirit, question thine heart: lest haply thou have the sacrament, and have not the virtue of the sacrament. Question thine heart. If love of thy brethren be there, set thy mind at rest. There cannot be love without the Spirit of God: since Paul cries, "The love of God is shed abroad in your hearts by the Holy Spirit which is given unto us."
Let him see, let him prove himself before the eyes of God, let him see whether there be in him the love of peace and unity, the love of the Church that is spread over the whole earth. Let him not rest only in his loving the brother whom he has before his eyes, for we have many brethren whom we do not see, and in the unity of the Spirit we are joined to them. What marvel that they are not with us? We are in one body, we have one Head, in heaven. Brethren, our two eyes do not see each other; as one may say, they do not know each other. But in the charity of the bodily frame do they not know each other? For, to shew you that in the charity which knits them together they do know each other; when both eyes are open, the right may not rest on some object, on which the left shall not rest likewise. Direct the glance of the right eye without the other, if thou canst. Together they meet in one object, together they are directed to one object: their aim is one, their places diverse. If then all who with thee love God have one aim with thee, heed not that in the body thou art separated in place; the eyesight of the heart ye have alike fixed on the light of truth.
In the earliest times, "the Holy Ghost fell upon them that believed: and they spake with tongues," which they had not learned, "as the Spirit gave them utterance." These were signs adapted to the time. For there behooved to be that betokening of the Holy Spirit in all tongues, to shew that the Gospel of God was to run through all tongues over the whole earth. That thing was done for a betokening, and it passed away. In the laying on of hands now, that persons may receive the Holy Ghost, do we look that they should speak with tongues? Or when we laid the hand on these infants, did each one of you look to see whether they would speak with tongues, and, when he saw that they did not speak with tongues, was any of you so wrong-minded as to say, These have not received the Holy Ghost; for, had they received, they would speak with tongues as was the case in those times? If then the witness of the presence of the Holy Ghost be not now given through these miracles, by what is it given, by what does one get to know that he has received the Holy Ghost? Let him question his own heart. If he love his brother the Spirit of God dwelleth in him.
"And he that keepeth His commandment" - ye see that none other thing is bidden us than that we love one another - "And he that keepeth His commandment shall abide in Him, and He in him." "And in this we know that He abideth in us, by the Spirit which He hath given us." Is it not manifest that this is what the Holy Ghost works in man, that there should be in him love and charity? Is it not manifest, as the Apostle Paul saith, that "the love of God is shed abroad in our hearts by the Holy Ghost which is given us"? For our apostle was speaking of charity, and was saying that we ought in the sight of God to interrogate our own heart. "But if our heart think not ill of us:" i.e. if it confess that from the love of our brother is done in us whatever is done in any good work.
And by this we know that He abides in us, by the Spirit whom He has given us. In the early times, the Holy Spirit fell upon believers, and they spoke in tongues which they had not learned. But now, because the holy Church does not need external signs, whoever believes in the name of Jesus Christ and has fraternal love bears witness to the Holy Spirit dwelling in them. For this is what the Holy Spirit does in a person, so that there is love in them. For love (says Paul) is poured into our hearts by the Holy Spirit who has been given to us (Rom. V). Yet because many, not having love, and by perverse doctrine tearing the unity of the Church, nonetheless contend that the Holy Spirit is in them, it is rightly added:
And he who keeps his commandments abides in him, and he in him. Let God therefore be your home, and be the home of God; abide in God, and let God abide in you. God abides in you to hold you, you abide in God so that you do not fall. Keep his commandments, hold onto charity. Do not separate yourself from faith in him, so that you glory in his presence, and you will remain secure in him, now through faith, then through sight. And he will remain eternally in you, as the Psalmist sings of him: They shall exult forever, and you will dwell in them (Psalm V).
And let us love one another, as he commanded; and whoever keeps his commandments abides in him, and he in them. And by this we know that he abides in us, by the Spirit whom he has given us.
This is, he says, let us love each other with true affection. And where did he command this? In these words, when he says: "As you wish that others would do to you, do so to them." (Matt. 7:12) Therefore, if we desire that our neighbors are truly and sincerely affectionate towards us, we must be entirely similarly affectionate towards them. If this is the Lord's command, much more if we abide in Him or are established in Him, He will also present Himself to us. (1 Tim. 2:15) For He cannot deny Himself: that is, He cannot be taken away, while He provides us with His commandments, but He first establishes these in Himself. However, if this is the case, certainly if we keep His commands, we will have Him listening to us in all that we ask of Him, and His gift will be firm in us. The whole sentiment of the rule is this: That we believe in the name of His Son Jesus Christ, and love one another truly, as His commandment is.
For whoever keeps His commandments abides in Him, and He in them. And by this we know that He abides in us, by the Spirit or gift which He has given us. Indeed, as long as this sanctuary remains, we undoubtedly have an indestructible gift of His. But how will it be a sanctuary? If we do not neglect anything of what He has commanded us regarding love.

Summary
First John 3:24 profoundly articulates the essence of the Christian life as a dynamic, reciprocal union with God, grounded in obedient living and unequivocally confirmed by the indwelling presence of the Holy Spirit. This verse serves as both a powerful assurance for believers and a clear indicator of genuine faith, emphasizing that true communion with God is manifested through adherence to His commands and verified by the Spirit's transformative work within.
Context
Literary Context
This verse concludes a significant section in 1 John (3:11-24) where the Apostle John sharply contrasts the "children of God" with the "children of the devil." The defining characteristic of God's children is their active love for one another, which is presented not as a mere sentiment but as a tangible expression of truth and action. This love is inextricably linked to obedience, specifically the dual commandment to "believe in the name of his Son Jesus Christ, and love one another, as he gave us commandment" (1 John 3:23). Verse 24, therefore, acts as a powerful summary and affirmation of the believer's intimate union with God, asserting that this union is both demonstrated by their conduct and verified by the divine presence within them. It builds on the preceding verses by providing the ultimate assurance of this relationship.
Historical & Cultural Context
John's epistles were likely written towards the end of the first century, addressing Christian communities facing internal challenges from false teachers (proto-Gnostics) who denied the true humanity of Christ and downplayed the importance of ethical conduct. These teachers often claimed a superior "knowledge" (gnosis) that supposedly transcended the need for obedience or love. In this context, John emphasizes practical righteousness and love as non-negotiable proofs of genuine faith, directly countering the antinomian tendencies of these heretical groups. The concept of "abiding" or "dwelling" (Greek: menō) was not unique to John but held profound significance in his theology, signifying a deep, continuous, and personal relationship, reminiscent of the covenantal language of the Old Testament where God "dwelt" among His people.
Key Themes
First John 3:24 contributes significantly to several overarching themes in the epistle. It powerfully reinforces the theme of Mutual Indwelling, where believers "dwell in Him, and He in them," echoing Jesus' teaching on abiding in Him found in John 15:4-7. This mutual indwelling is presented as a consequence of Obedience to God's Commandments, particularly the command to love, which John reiterates throughout the letter (e.g., 1 John 2:3-6). Furthermore, the verse highlights the crucial role of Assurance of Salvation, providing a tangible, internal witness—the Holy Spirit—as proof of God's abiding presence. This theme of assurance is vital for believers grappling with doubt and is further expounded in passages like 1 John 5:13.
Exposition and Analysis
Key Word Analysis
This word signifies to guard (from loss or injury, properly, by keeping the eye upon), to note (a prophecy; figuratively, to fulfil a command), or to maintain. In this context, it emphasizes an active, watchful, and diligent adherence to God's commandments, not merely a passive acceptance. It implies a sustained effort to observe and obey, reflecting a heart devoted to God's will.
This primary verb means to stay, remain, continue, or live. John uses it extensively to describe a continuous, intimate, and active relationship. It implies not a temporary visit but a permanent, living connection, emphasizing a dynamic, ongoing communion rather than a static state. This "abiding" is the very essence of the union described between God and the believer.
Derived from a word meaning "a current of air," this term refers to breath, a breeze, or, by analogy, a spirit. In this context, it specifically denotes the Holy Spirit, the divine Person who indwells believers. The Spirit's presence is the tangible, internal witness that confirms the reality of God's abiding presence in the believer's life, providing assurance and empowering obedience.
Verse Breakdown
"And he that keepeth his commandments dwelleth in him, and he in him."
This opening clause establishes the reciprocal nature of the divine-human relationship. The act of "keeping His commandments" (referring to God's commands, especially belief in Jesus and love for one another as per 1 John 3:23) is presented as the condition and evidence of "dwelling in Him." The phrase "and he in him" completes the reciprocity, signifying God's active, intimate, and continuous presence within the obedient believer. This mutual indwelling speaks to a profound spiritual union, a shared life where God's presence transforms and empowers.
"And hereby we know that he abideth in us, by the Spirit which he hath given us."
This second clause provides the definitive means by which believers can be assured of this mutual indwelling. The "hereby" (Greek: toútōi) points to the subsequent phrase: "by the Spirit which he hath given us." The Holy Spirit is not merely a feeling but a divine Person, a gift from God, whose indwelling presence serves as the internal, undeniable witness to God's abiding within the believer. The Spirit's presence is the objective, divine seal of this relationship, providing both conviction and comfort, and confirming the reality of their union with God.
Literary Devices
The verse employs several significant literary devices. Chiasmus is subtly present in the structure of the first clause, "he that keepeth his commandments dwelleth in him, and he in him," creating a symmetrical balance that emphasizes the reciprocal nature of the relationship. The repetition of "in him" highlights the profound Intimacy and union between God and the believer. Furthermore, the verse uses Metonymy where "the Spirit" stands for the Spirit's work, witness, and effects within the believer. The Spirit is the tangible sign, the evidence, through which "we know" God abides in us. The entire verse functions as a powerful Affirmation and Assurance, providing comfort and confidence to those who genuinely seek to live in obedience to God.
Theological and Thematic Connections
First John 3:24 is a cornerstone verse for understanding the nature of the Christian life as one of profound, intimate union with God. It beautifully intertwines the themes of obedience, divine indwelling, and spiritual assurance. The "keeping of commandments" is not presented as a legalistic burden but as the natural outflow of a heart transformed by God's love, enabling a deeper, continuous communion. This obedience is the visible fruit of an invisible reality—God's Spirit at work within. The Spirit's presence is the ultimate divine guarantee, providing an internal witness that transcends mere human understanding or feeling, confirming the believer's authentic relationship with the Father and the Son.
Reflection and Application
This verse offers immense comfort and clarity for the believer's journey. It reminds us that our relationship with God is not static or merely intellectual, but a dynamic, living communion. The call to "keep His commandments" (which, as John clarifies, includes believing in Jesus and loving one another) is not a path to earn God's favor, but the natural response of a heart that desires to remain in His presence and experience His transforming power. When we strive to live in obedience, guided by the Spirit, we find ourselves more deeply connected to God, and His presence becomes more evident in our lives. Conversely, the inner witness of the Holy Spirit—His conviction, comfort, guidance, and the fruit He produces—serves as a powerful, undeniable confirmation that God truly abides in us. This dual assurance, both external (obedience) and internal (Spirit's witness), provides a robust foundation for Christian confidence and spiritual discernment, encouraging us to lean into the Spirit's leading and pursue a life that honors our indwelling Lord.
Questions for Reflection
FAQ
How does "keeping His commandments" relate to salvation by grace through faith?
First John 3:24 does not present "keeping commandments" as a means to earn salvation, but rather as the evidence and outflow of a saving relationship already established by grace through faith. Salvation is indeed a free gift received by faith in Jesus Christ, as articulated in Ephesians 2:8-9. However, genuine faith is never barren; it always produces fruit. Obedience, especially the command to love God and neighbor, is the natural, Spirit-empowered response of a heart transformed by God's grace. It is the visible manifestation that one truly "dwells in Him" and that He "abides in us." Therefore, obedience is not the root of salvation but its fruit and an ongoing expression of the believer's union with Christ.
What does it mean for God to "dwell in him, and he in him"?
This phrase describes a profound, reciprocal, and intimate spiritual union between God and the believer. For the believer to "dwell in Him" means to live in continuous communion, dependence, and fellowship with God, making Him the sphere and source of one's life. It signifies a life lived in accordance with God's will and character. For God to "dwell in him" (the believer) means that God's active, empowering, and transforming presence is within the believer, guiding, comforting, and enabling them to live a life pleasing to Him. This mutual indwelling is a mystical yet real union, a shared life that reflects the relationship between Jesus and the Father, as seen in John 17:21-23. It implies a dynamic, ongoing relationship where God's Spirit is actively at work within the believer.
Christ-Centered Fulfillment
First John 3:24 finds its ultimate fulfillment and deepest meaning in the person and work of Jesus Christ. The "commandments" that believers are called to keep are not arbitrary rules but are fundamentally rooted in the teachings and example of Jesus, who perfectly embodied obedience to the Father (John 15:10). Moreover, the concept of "dwelling in Him, and He in him" is a direct echo of Christ's own teaching on abiding in Him as the true vine (John 15:4-5). Jesus promised to send the Holy Spirit, the "Helper," who would "abide with you forever" (John 14:16), and it is this very Spirit, given by Christ, who now confirms the believer's union with God. Thus, the obedience spoken of is empowered by Christ's Spirit, and the assurance of God's indwelling is a direct result of Christ's finished work on the cross and His subsequent sending of the Spirit. The verse points to the reality that through Christ, believers are brought into the very life of the Trinity, experiencing a divine intimacy made possible only through His atoning sacrifice and continuous intercession (Hebrews 7:25).
