John Gill's Exposition of the Whole Bible
Job 12:22
He discovereth deep things out of darkness,.... The deep things of God, his own deep things which lie in his heart, wrapped up in darkness impenetrable to creatures, and which could never be known unless he had discovered them; such as the thoughts of his heart, which are very deep, Psalms 92:5; the deep things of God, which the Spirit of God only knows, searches, and reveals, 1 Corinthians 2:10; even his thoughts of peace, and good things for his people, which are many and precious, are known to himself, and made known to them, or otherwise must have remained in darkness, and out of their reach, being as high as the heavens are from the earth; the decrees and purposes of God, which he hath purposed in himself, are deep things in his own breast, and lie concealed in darkness there, until discovered by the accomplishment of them; such as his decrees of election in Christ, redemption by him, and the effectual calling by his grace; all which are revealed and made known by the execution of them: the love of God to his people, which lay hid in his heart from everlasting; this is discovered by the gift and mission of his Son; in the regeneration and quickening of his people, and of which he makes still larger discoveries to them in the course of their lives: likewise the mysteries of the Gospel, unknown to natural men, even the wise and prudent, only known to such to whom it is given to know them, to whom they are revealed by the Father of Christ, and by the Spirit of wisdom and revelation in the knowledge of the mystery of God, and of the Father, and of Christ; respecting the persons in the Godhead, the grace of each person, the incarnation of Christ, the union of the two natures in him, redemption and justification by him, regeneration by the Spirit of God, union to Christ, and communion with him, and conformity to him in soul and body, now and hereafter: likewise the secrets of his providence, in which there is a great depth of his wisdom and knowledge, and is in great obscurity; his path is in the great waters, and his footsteps are not known; his judgments are unsearchable, and his ways past finding out, but before long they will be made manifest, and lie open to view. There are also the deep things of others, which he discovers, as the depth of sin in the deceitful heart of man, which none knows as himself; and which lie hid there until they are discovered in the light of the divine Spirit, who convinces of them, enlightens the understanding to behold those swarms of lusts and corruptions it never discerned before; and then a man comes to see and know the plague of his own heart, he was before a stranger to; also the depths of Satan, his deep laid schemes, his wiles and stratagems, to draw into sin, and so to ruin; these are unknown to natural men, but saints are made acquainted with them, so that they are not altogether ignorant of his devices, Revelation 2:24; likewise the secret plots, counsels, and combinations of wicked men, which they lay deep, and seek to hide from the Lord, being formed in the dark; but he sees and knows them, discovers and confounds them: to which may be added all the wicked actions of men done in the dark, but cannot be hid from God, with whom the darkness and the light are both alike; and who, sooner or later, brings them to light, even the hidden things of darkness, and makes manifest the counsels of the heart, as he will do more especially at the day of judgment, to which every secret thing will be brought:
and bringeth but to light the shadow of death; not only life and immortality, as by the Gospel, but death, and the shadow of it, even deadly darkness, the grossest of darkness; such who are darkness itself he makes light, and out of the darkness in them commands light to shine, as in the first creation; to them that sit in darkness, and in the shadow of death, he causes a great light to arise, the light of the Gospel, and the light of grace, yea, Christ himself, the light of the world; he calls and brings them out of it into marvellous light, out of the dark dungeon and prison of sin and unbelief, to the enjoyment of spiritual light and life here, and to everlasting light and glory hereafter.
