When one carries unforgiveness in one’s heart, the word says it will hinder your prayers.
Forgiveness is for YOU, not the offender. The offender doesn’t even need to know he’s been forgiven, but telling him might be enough to break into a hardened heart.
Forgiveness doesn’t let him off the hook, he’ll still have to face the consequences.
Matthew 6:12-15
“And forgive us our debts, As we forgive our debtors. And do not lead us into temptation, But deliver us from the evil one. For Yours is the kingdom and the power and the glory forever. Amen. “For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.”
