For if ye forgive men their trespasses, your heavenly Father will also forgive you:
Matthew 6:14 (KJV)
What Does Matthew 6:14 Mean
This message on forgiveness is clear. When we forgive, God forgives us also. In Matthew 6:15, it is explained that if we do not forgive, we also are held bound.
This message of forgiving others in order to be forgiven is mirrored in Luke 6:37.
