'Forgiving' in the Bible

and said, “I assure you and most solemnly say to you, unless you repent [that is, change your inner self—your old way of thinking, live changed lives] and become like children [trusting, humble, and forgiving], you will never enter the kingdom of heaven.

Therefore, whoever humbles himself like this child is greatest in the kingdom of heaven.

Be kind and helpful to one another, tender-hearted [compassionate, understanding], forgiving one another [readily and freely], just as God in Christ also forgave you.
