When someone sins against us, we are to go to him and tell him about it. If he repents, forgive him. If he sins against us many times a day, then repents afterwards, we must forgive him for every time.
Luke 17:3,4 NLT ... If another believer (your brother) sins, rebuke him; then if there is repentance, forgive. Even if that person wrongs you seven times a day and each time turns again and asks forgiveness, you must forgive.
Even Jesus forgave the men who crucified Him. The ultimate prayer for forgiveness is in John 17. He asked the Father to forgive them because they didn't know what they were doing. When people sin against us, they don't know what they're doing.
Luke 23:24 NLT ... Jesus said, "Father, forgive them, for they don't know what they are doing."
When we forgive the ones who sin against us, our Heavenly Father calls us kind and tenderhearted.
Ephesians 4:32 NLT ... Be kind to each other, tenderhearted, forgiving one another, just as God through Christ has forgiven you.
We are to be gentle, forebearing one another.
Colossians 3:13 NLT ... Make allowance for each other's faults. Forgive anyone who offends you. Remember, the Lord forgave you, so you must forgive others.
When we have a complaint or difference with another person, we must forgive and pardon him.
Jesus has freely forgiven us, so it's a must for us to forgive in order for the Lord to forgive us.
