Ephesians 4:32 says, “And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.”
Because God has forgiven us, we are to forgive each other. If God forgave our sins in the same way we forgive others, none of us would be forgiven. But after we have become children o God, because we have been forgiven, we are to forgive!
