12 Now that he was in trouble, he went to his knees in prayer asking for help - total repentance before the God of his ancestors. 13 As he prayed, God was touched; God listened and brought him back to Jerusalem as king. That convinced Manasseh that God was in control. 14 After that Manasseh rebuilt the outside defensive wall of the City of David to the west of the Gihon spring in the valley. It went from the Fish Gate and around the hill of Ophel. He also increased its height. He tightened up the defense system by posting army captains in all the fortress cities of Judah. 15 He also did a good spring cleaning on The Temple, carting out the pagan idols and the goddess statue. He took all the altars he had set up on The Temple hill and throughout Jerusalem and dumped them outside the city. 16 He put the Altar of God back in working order and restored worship, sacrificing Peace-Offerings and Thank-Offerings. He issued orders to the people: "You shall serve and worship God, the God of Israel." 17 But the people didn't take him seriously - they used the name "God" but kept on going to the old pagan neighborhood shrines and doing the same old things. 18 The rest of the history of Manasseh - his prayer to his God, and the sermons the prophets personally delivered by authority of God, the God of Israel - this is all written in The Chronicles of the Kings of Israel. 19 His prayer and how God was touched by his prayer, a list of all his sins and the things he did wrong, the actual places where he built the pagan shrines, the installation of the sex-goddess Asherah sites, and the idolatrous images that he worshiped previous to his conversion - this is all described in the records of the prophets. 20 When Manasseh died, they buried him in the palace garden. His son Amon was the next king.

(Read 2 Chronicles 33:1-20)
We have seen Manasseh's wickedness; here we have his repentance, and a memorable instance it is of the riches of God's pardoning mercy, and the power of his renewing grace. Deprived of his liberty, separated from his evil counsellors and companions, without any prospect but of ending his days in a wretched prison, Manasseh thought upon what had passed; he began to cry for mercy and deliverance. He confessed his sins, condemned himself, was humbled before God, loathing himself as a monster of impiety and wickedness. Yet he hoped to be pardoned through the abundant mercy of the Lord. Then Manasseh knew that Jehovah was God, able to deliver. He knew him as a God of salvation; he learned to fear, trust in, love, and obey him. From this time he bore a new character, and walked in newness of life. Who can tell what tortures of conscience, what pangs of grief, what fears of wrath, what agonizing remorse he endured, when he looked back on his many years of apostacy and rebellion against God; on his having led thousands into sin and perdition; and on his blood-guiltiness in the persecution of a number of God's children? And who can complain that the way of heaven is blocked up, when he sees such a sinner enter? Say the worst against thyself, here is one as bad who finds the way to repentance. Deny not to thyself that which God hath not denied to thee; it is not thy sin, but thy impenitence, that bars heaven against thee.
