Be always greatly abased for your remaining sin and never think that you lie low enough for it. But yet, don't be at all discouraged or disheartened by it. For though we are exceedingly sinful, yet we have an advocate with the father, Jesus Christ the righteous, the preciousness of whose blood and the merit of whose righteousness and the greatness of whose love and faithfulness does infinitely overtop the highest mountains of our sin. Jonathan Edwards.

Their heart was not steadfast toward him. They were not faithful to his covenant, yet he, being compassionate, atoned for their iniquity and did not destroy them. He restrained his anger often and did not stir up all His wrath. Psalms 78:37-38.
