"If we walk in the light as He is in the light, we have fellowship one with another, and the blood of Jesus Christ His Son cleanses us from all sin"(1 John 1:7). Through the gospel, as believers see the truth of Christ by the Holy Spirit. We are able to walk daily in the light of Christ.
"For it is God who commanded light to shine out of darkness, who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ" (2 Corinthians 4: 6). That is the light of the Holy Spirit. Our hearts are enlightened to see the glory of God in Christ.
Light comes to our hearts through the gospel of Christ (1 Thessalonians 1:5). The change is sudden and abrupt. It's like turning on a light in a dark room. That's the way the Spirit of light changes those who have lived in darkness. New birth scatters our darkness into light.
The Holy Spirit brings us out of darkness into the light without any resistance. It comes by new birth, through faith in the Lord Jesus Christ. It is not our achievement. Rather, illumination of the Spirit comes from without, changing our hearts within. Jesus is the light, as the Holy Spirit opens "the eyes of your understanding"(Ephesians 1:18).
