We lived in sin and darkness (Eph. 2:1-3; Matt. 4:16), but the light of the Lord has enlightened us. He has turned us from the darkness and sin that we previously loved to the light of the glorious gospel. We were blinded by sin and Satan, but God has shone His light in us–
2 Cor. 4:4-6 In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the Image Of God. 5 For what we proclaim is not ourselves, but Jesus Christ as Lord, with ourselves as your servants for Jesus’ sake. 6 For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.
We were held in darkness by the god of this world, but God in His mercy has reached down to us and shone the light of Christ in us. This work is described as nothing other than a re-creation. Just like God, at the beginning said “Let there be light” (Gen. 1:3), so likewise there had to be a work of spiritual creation in our hearts. He made the light of Christ to shine so that we would see the glory of God, Who is actually a person, even our Lord Jesus Christ. He shone the light of the gospel so that we would acknowledge Him as the Lord of everything and the Savior of our souls. So that we would see His beauty and treasure Him above all things as the satisfaction of our souls.
Eph. 1:17-18 that the God of our Lord Jesus Christ, the Father of glory, may give you the Spirit of wisdom and of revelation in the knowledge of him, 18 having the eyes of your hearts enlightened, that you may know what is the hope to which he has called you, what are the riches of his glorious inheritance in the saints,
Paul prays that the believers may more and more know God intimately and understand His work. He prays that God would especially reveal to us Himself and the riches of the salvation that He has given us. He prays that we would be freed from our sin and made children of the living God. He wants not their physical eyes, but their spiritual eyes—the eyes of their hearts, to be enlightened so that they may, at the present, behold the glory of God and in the future, in our flesh see God (Job 19:26-27). God reveals Himself to His children through His Spirit and infallible Word.
The natural person does not understand the things of God, but the one who is spiritual, i.e., led by the Spirit, is made able to understand the things of God (1 Cor. 2:9-16). We have received the mind of Christ in His Word and Spirit to understand the things of God. This is not given to everyone but only to those who are led by the Spirit of Christ and who are called according to His purpose. The apostle calls us to continually strive to live according to God’s will, which is revealed in the Holy Scriptures. We are not to be conformed to the pattern of this world, rather we are to “be transformed by the renewal of [our] mind[s]” so that we would know what God’s will is for us (Rom. 12:2). We are commanded to continually walk according to the light given to us in Jesus Christ our Lord.
Renewal of Nature
We are renewed. A completely new nature is given to us at the new birth. Paul says that when we are in Christ, we become a new creation. The old passes away, but now the new has come (2 Cor. 5:17). There is a change in nature through which we are now willing t...
