For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins.
1 John 1:9
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
This is my blood of the covenant, which is poured out for many for the forgiveness of sins.
