2 Cor. 4:6 For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. Gen. 1:2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. 3 ¶ And God said, Let there be light: and there was light. It is not difficult to see the analogy between 2 Cor. 4:6 and Genesis 1:2-3. In both cases there is darkness. For example just prior to 2 Cor. 4:6 Paul says: In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. 2 Cor. 4:4 In both cases, light is a direct results of the command of God. 1. And GOD SAID, let there be light and there was light 2. For God who commanded the light to shine out of darkness, hath shined... This "power" or the power to command light to shine in the darkness of the human heart is not of Paul but "of God" But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us. - 2 Cor. 4:7 This "power" is in direct relationship to preaching the gospel when the gospel is used as the CREATIVE WORD of God or infused by His power to call spiritual light into existence within the darkness of the unregenerated mind: "Of His own will begat he us by the word of truth" - James 1:18 "Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.....And this is the word which by the gospel is preached unto you." - 1 Pet. 1:23 However, this does not refer to the gospel when it comes in "word only" but only when it "comes in power, and in the Holy Spirit and in much assurance" (1 Thes. 1:5). When it becomes the CREATIVE WORD OF COMMAND OF GOD, then it is the "power of God" unto salvation (Rom. 1:16). As the CREATIVE WORD or COMMAND of God it produces "the light of knowledge of God in the face of Jesus Christ" (2 Cor. 4:6) which replaces the darkness, ignorance and blindness that characterizes the unregenerate mind: Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart: - Eph. 4:18 It is this darkened condition that "alienated them from the life of God" and thus they are SPIRITUALLY DEAD. This condition is reversed by the DIVINE FIAT or word of command in 2 Cor. 4:6: For God, who commanded the light to shine out of darkness,hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. This "light of knowledge" concerning God through Jesus Christ in context is the message of the gospel (vv. 5,7) and it is this knowledge with the hope expressed in the gospel that forms the "substance" of saving faith and thus the "hope" of saving faith, as well as BEING the basis for inward "persuasion" and thus the creation of faith in the darkened heart by dvine fiat. "For faith cometh by hearing and hearing by GOD'S WORD OF COMMAND [rhema]" - Rom. 10:17. Paul does not use the Greek term "logos" in Romans 10:17 that is the usual term translated "word" and conveys the idea of invisible thoughts revealed but uses the term "rhema" which is the common word to characterize any command. The "hearing" produced by God's word of command in Romans 10:17 is the same hearing mentioned in John 6:45 as a direct result of God drawing/teaching "Every man that hath "HEARD" and "LEARNED" of the Fahter COMETH UNTO ME." Hence, drawing by the Father is by the WORD OF COMMAND that produces a hearing ear and coming to Christ in faith. This word of command that replaces darkness with light in the heart (which darkness alienates him from eternal life) restores eternal life, creates faith and thus is the command of God that translates a sinner out of darkness into the kingdom of light or the effectual call.
