““Manasseh king of Judah has committed these detestable sins. He has done more evil than the Amorites who preceded him and has led Judah into sin with his idols. Therefore this is what the Lord, the God of Israel, says: I am going to bring such disaster on Jerusalem and Judah that the ears of everyone who hears of it will tingle. I will stretch out over Jerusalem the measuring line used against Samaria and the plumb line used against the house of Ahab. I will wipe out Jerusalem as one wipes a dish, wiping it and turning it upside down.” – 2 Kings 21:11-13 NIV

Manasseh did all of the detestable practices he was interested in like:

“He rebuilt the high places his father Hezekiah had destroyed; he also erected altars to Baal and made an Asherah pole, as Ahab king of Israel had done. He bowed down to all the starry hosts and worshiped them. He built altars in the temple of the Lord, of which the Lord had said, “In Jerusalem I will put my Name.” In the two courts of the temple of the Lord, he built altars to all the starry hosts. He sacrificed his own son in the fire, practiced divination, sought omens, and consulted mediums and spiritists. He did much evil in the eyes of the Lord, arousing his anger.” – 2 Kings 21:3-6 NIV

Because of committing all of these evil acts, Manasseh all but sealed Israel’s fate as a nation to be exiled. God had prophesied disaster on the southern nation of Judea. Obviously this is because of Manasseh’s decision to follow the path of evil as Israel’s representative as well as Israel’s longstanding issue with sin and rebellion. We as Christians need to focus on being proper in our conduct. The law isn’t the focus anymore (Romans 7), but that doesn’t mean we should just go on sinning (Romans 6)? Since we were freed from sin, we can do better things. We don’t have to worry about the judgement of our actions as Christ paid our price unlike Israel at that time, but we should still do our best to help demonstrate the goodness of the good news of why Christ is good.
