Unbelief and darkness are one, Hence God delivers the elect from darkness/unbelief Col 1:13
Who hath
delivered us from the power of darkness, and hath translated
us into the kingdom of his dear Son:
John Gill comments on Col 1:13
Gill's Exposition of the Entire Bible
Who hath delivered us from the power of darkness,.... That is, from the power of Satan; see Acts 26:18, who, though once an angel of light, is now darkness itself, and is reserved in chains of darkness; he is a ruler of the darkness of this world; his kingdom is a kingdom of darkness; and he blinds the minds of them that believe not, keeps them in darkness, and increases the natural darkness of their minds; he delights in works of darkness, and tempts men to them; and his everlasting state and portion will be blackness of darkness: his power over men, in a state of unregeneracy, which he usurps, and is suffered to exercise, is very great; he works effectually in them, and leads them captive at his will; and nothing less than the power of God, who is stronger than the strong man armed, can deliver out of his hands; and which is at least one part of the mercy for which thanks are here given; See Gill on
Luke 22:53;
with the Jews, one of the names of Satan is "darkness" (e). Moreover, the darkness of sin, ignorance, and unbelief, with which God's elect, while in a state of nature, are surrounded, and, as it were shut up and imprisoned, so that they have not the least spark of true spiritual light and knowledge, may be also meant; under the power of which they are to such a degree, that they know nothing of God in Christ, of the way of salvation by him, or of the work of the Spirit on their souls, or of the doctrines of the Gospel in an experimental manner; and so they continue, till, by an almighty power, they are turned from darkness to light; when, by powerful grace, they are plucked as brands out of the burning, and delivered from wrath to come, and from that utter darkness of misery and destruction their ways of sin and darkness led and exposed them to. This deliverance is wrought out for them in the effectual calling, when they are internally called, and powerfully brought out of this darkness, by introducing light into them, revealing Christ in them, causing the prince of darkness to flee from them, and the scales of darkness and blindness to fall from their eyes; and which is both an instance or the wonderful grace of God, and of his almighty power, and in which lies in part the saints' meetness for the inheritance; for these words are, in some sort, explanative of the former; for so long as a person is under the power of darkness, he cannot be meet for an inheritance which is in light: it follows, as another branch of this mercy, for which thanks are given,
