I Kings 8:50 And forgive thy people that have sinned against thee, and all their transgressions wherein they have transgressed against thee, and give them compassion before them who carried them captive, that they may have compassion on them: 51 For they be thy people, and thine inheritance, which thou broughtest forth out of Egypt, from the midst of the furnace of iron:
This is an amazing picture. He forgives those that He has rescued. He forgives those that He has forgiven. He brought them out of Egypt. He made them His people.
They do sin but He is a forgiving God. He shows compassion. They suffer the consequences of their sins but He is ever ready to forgive and bring them back.
