Manasseh sought the Lord his God and sincerely humbled himself before the God of his ancestors - 3 Chronicles 33:12-13
Times of stress can motivate a man to do little self-examination
Manasseh made sinning into personal art form:
God warned Manasseh that he would pay for his sins but he refused to listen
Assyrian forces invaded Judah and took him away to Babylon for 12 years of suffering
The once proud Manasseh humbled himself saying "The Lord alone is God!"
