"If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by 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, his Son, purifies us from all sin."
"If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness." (1 John 1:6-9)
"Praise the LORD, O my soul; all my inmost being, praise his holy name."
"Praise the LORD, O my soul, and forget not all his benefits -- who forgives all your sins and heals all your diseases, who redeems your life from the pit and crowns you with love and compassion, who satisfies your desires with good things so that your youth is renewed like the eagle's." (Psalms 103:1-5)
"Come now, let us reason together," says the LORD.
Though your sins are like scarlet, they shall be as white as snow;
though they are red as crimson, they shall be like wool." (Isaiah 1:18)
"In him you were also circumcised, in the putting off of the sinful nature, not with a circumcision done by the hands of men but with the circumcision done by Christ, having been buried with him in baptism and raised with him through your faith in the power of God, who raised him from the dead."
"When you were dead in your sins and in the uncircumcision of your sinful nature, God made you alive with Christ. He forgave us all our sins, having cancelled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross. And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross." (Colossians 2:11-15)
