Job 37:3

35. As if it were plainly said; He who rules over the highest things, forsakes not even the most remote. Because His watchful rule is so directed towards the greatest concerns, as not to be kept from those which are little. For He Who is every where present, and every where equal, is not unlike Himself, even in unlike circumstances. He therefore equally regards all things, equally disposes all things, Who, though present in all places, is not locally confined, nor varied by attending to various concerns. But if we understand by the heavens, holy preachers, (as the Prophet attests who says, The heavens declare the glory of God;) [Ps. 19, 1] after the coming of the Holy Spirit is designated by the sound of the mouth, it is rightly subjoined, He Himself considereth under all the heavens, and His light is over the ends of the earth.
36. For there are some, who, when they hear the wonderful works of the Apostles, (that they raised the dead by the Holy Spirit which they had received, cast out devils from the possessed, removed infirmities by their shadow, foretold future events by prophecy, and, speaking in the tongue of all nations, preached the Only Begotten Word of God;) because they do not see these powers now in the Church, suspect that the grace of heaven has been already withdrawn from the Church, forgetting to consider that it is written, An assister in needful times, in tribulation. [Ps. 9, 9] For Holy Church required then the assistance of miracles, when the tribulation of persecution oppressed her. For after she has overcome the pride of unbelief, she requires no longer the signs of miracles, but the merits of deeds alone, though she displays even them by many persons, when opportunity demands. For it is written, Tongues are for a sign not to them that believe, but to them that believe not. [1 Cor. 14, 22] Where then all are faithful, what cause demands signs to be displayed? On which head perhaps we the more readily give satisfaction, if we make some mention of the Apostolic dispensation.
37. For Paul, the illustrious preacher, coming to Melite, and knowing the island to be full of unbelievers, healed by his prayers the father of Publius, afflicted with dysentery and fevers; [Acts 28, 8] and yet advised Timothy when sick, saying, Use a little wine for thy stomach’s sake, and thine often infirmities. [1 Tim. 5, 23] Why is it, O Paul, that thou restorest the sick unbeliever to health by thy prayers, and yet healest so great a defender of the Gospel by food, like a physician? except that outward miracles are wrought, in order that the minds of men may be brought to inward truths; that so by the wonder which is visibly displayed, those invisible truths, which are more wonderful, may be believed? For the father of Publius required to be healed by a sign of power, in order that he might revive in mind, while returning to health by a miracle. But no miracle needed to be manifested outwardly to Timothy, because he was already full of life within. What wonder is it then, that miracles are not frequently displayed, when the faith has been spread abroad, when even the Apostles themselves performed them not in the case of some who already believed? The heavens, then, having been raised up, the Lord considers inferior objects; because, when the greatest preachers have been taken away, He constantly regards even the lowliness of our infirmity. And His light beholds, as it were, the ends of the earth, under the heavens; because, after the sublime doings of those who have gone before, He embraces the ways and doings even of sinners by the illumination of His grace. And though He does not now frequently manifest miraculous signs, by the life of believers, He yet departs not from these same believers by the virtue of works. But His light over the ends of the earth can also be thus understood; that whilst the preaching of heavenly Grace gathers the nations to the faith, it has embraced within itself the boundaries of the world.
38. Or, certainly, the ends of the earth are the ends of sinful men. And it is often the case, that many forsake God, and waste the seasons of their life in carnal desires. But yet, when looked down upon by Divine Grace, they turn to God at their latter end, they learn what are the eternal judgments, and punish with tears all the evil deeds they remember to have committed; and prove by their upright conduct that they are sincerely prosecuting these. And when righteousness succeeds, their former sin is surely entirely forgiven. For hence Hannah says by the spirit of prophecy, The Lord shall judge the ends of the earth; [1 Sam. 2, 10] because doubtless God does not judge the former life of sinners, when, by a look of affection from above, He enlightens their latter end. Hence Moses says, The firstling of an ass thou shall exchange for a sheep. [Ex. 13, 13] For, by an ass is designated uncleanness, but by a sheep, innocence. To exchange then the firstling of an ass for a sheep, is to convert the beginnings of an impure life into the simplicity of innocence; in order that a sinner, after having committed those deeds which the Lord rejects as unclean, may now display such conduct, as He can offer to God as a sacrifice. Because then a sinner is converted after his sins, and is brought back at last from the darkness of his misdeeds, at the end of his life, it is now rightly said, And His light is over the ends of the earth. But that very grace, which fills the mind after sins, affects it with great grief. For it recals evil deeds to the memory, and shows a man how justly he is to be condemned. Whence it comes to pass, that he bewails with daily floods of tears every sin which he remembers to have committed, and the more he is now able to discern what is righteous, the more ardently does he desire to punish his own wicked self with groans.

“Behind him the thunder will roar.” Certainly God transforms into tears the life of him whom he filled with his illumination, and the more he reminds the illuminated soul of eternal punishments, the harder he submits it to the groans for its past wickedness; and so a person feels the pain for what he has been, because he begins by now to see the good he did not do, he hates himself for what he has been, and he loves himself for what he should have been.… “He will thunder with the voice of his greatness.” God thunders with the voice of his greatness when he suggests to us, who are now well disposed through our tears, how great he is there on high.… “And after hearing his voice, nobody will be able to investigate.” The voice of God is heard when the soul perceives the inspiration of his grace.… But not even the soul illuminated by it can investigate this voice of the Spirit, which reaches and penetrates the ear of the heart.

[By] the words “the judgment that comes from his mouth; under the whole heaven he will be praised,” [the author] speaks about the thunder that is produced in the instant itself, in which punishment is inflicted on sinners; it is heard everywhere and everyone who hears it praises God.
