1 John 1:9
If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
Then Peter came and said to Him, "Lord, how often shall my brother sin against me and I forgive him? Up to seven times?" 22 Jesus said to him, "I do not say to you, up to seven times, but up to seventy times seven.
For if you forgive others for their transgressions, your heavenly Father will also forgive you. 15 "But if you do not forgive others, then your Father will not forgive your transgressions.
