As believers, we will never experience joy-filled, victorious lives unless we are ready to forgive people. This is something we are going to have to do frequently, and according to Matthew 18:21-22, even repeatedly. The Lord tells us plainly in the Bible that if we will not forgive other people for the wrong things they have done against us, then God will not forgive the wrong things we have done against Him. See Matthew 6:14-15.
What kind of condition would we be in if God refused to forgive us? We could not possible have a proper relationship with Him. Everything in our lives would be stopped up. We like to think that we can stay angry with other people and yet go to God and receive forgiveness for our sins. But the Lord tells us in the Bible that this is not so.
Jesus taught us to pray,” And forgive us our debts, as we also have forgiven ( left, remitted, and let go of the debts, and have given up resentment against) our debtors” Matthew 6:12. God is a God of mercy, and this issue of forgiveness is very important to Him. He tells us repeatedly in His Word that if we want mercy, we have to give mercy.
