Walking in the light

"But if we walk in the light as he is in the light, then we have fellowship with one another, and the blood of his Son Jesus cleanses us from all sin." (1 John 1: 7)

To walk by the light means to walk by the light of the word. Christ is the light of the world. He is also the Word of God.

When we accept Christ as our Savior and live by the light of His word, His blood cleanses us from all sin.
