II Kings 21

"And he built altars in the house of the Lord, of which the Lord had said, ‘In Jerusalem I will put My name'" (v5). King Manasseh of Judah was more wicked than the Amorites (v11). He sacrificed his son to idols and practiced witchcraft (v6). The "altars" he set up in Solomon's Temple were fertility goddesses(v7). This was the very Temple where God had promised to dwell in a special relationship with His people.

God does not allow us to combine faith in Him with faith in any other ritual, person, or idea. He wants our hearts to be completely His.
