Romans 6:4

Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

I John 1:5-7

This is the message we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.

II Corinthians 5:17

Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
