WNT(i)
6 If, while we are living in darkness, we profess to have fellowship with Him, we speak falsely and are not adhering to the truth.
7 But if we live in the light as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, cleanses us from all sin.
8 If we claim to be already free from sin, we lead ourselves astray and the truth has no place in our hearts.
9 If we confess our sins, He is so faithful and just that He forgives us our sins and cleanses us from all unrighteousness.
