1 John 1:7-10

But if we keep living in the pure light that surrounds him, we share unbroken fellowship with one another, and the blood of Jesus, his Son, continually cleanses us from all sin. If we boast that we have no sin, we’re only fooling ourselves and are strangers to the truth. But if we freely admit our sins when his light uncovers them, he will be faithful to forgive us every time. God is just to forgive us our sins because of Christ, and he will continue to cleanse us from all unrighteousness. If we claim that we’re not guilty of sin when God uncovers it with his light, we make him a liar and his word is not in us.
