King David said, “The law of the LORD is perfect, converting the soul” (Psalm 19:7). What he meant by that was there was contained within the Mosaic Law enough evidence to convict every person of their own sinful nature. Even if you narrowed God’s law down to just the Ten Commandments, everyone would be found guilty. Therefore, the law of Moses was able to bring people in the Old Testament to a place of repentance where they recognized their need for salvation.
Over time, the Israelites’ hearts became hardened and they were unwilling to repent and turn to God. The process of conversion is really a matter of repentance more than anything else. The word convert is translated from the Hebrew verb shuwb (shoob). “The basic meaning of this verb is movement back to the point of departure…The process called conversion or turning to God is in reality a re-turning or a turning back again to Him from whom sin has separated us, but whose we are by virtue of creation, preservation and redemption” (7725).
The life of Manasseh king of Judah illustrates the process of conversion perfectly. Manasseh’s father, king Hezekiah was a righteous man who trusted God and he was able to prevent Judah from being taken into captivity by the Assyrians, but Manasseh chose to do that which was “evil in the sight of the LORD” (2 Chronicles 33:2). Manasseh not only practiced idolatry, but is says in 2 Chronicles 33:6 that he “observed times, and used enchantments, and used witchcraft, and dealt with a familiar spirit, and with wizards.”
Manasseh had a very negative influence on the people of Judah. As their king, he had the power to force them to worship as he did. It says in 2 Chronicles 33:9-10, “Manasseh made Judah and the inhabitants of Jerusalem to err, and do worse than the heathen, whom the LORD had destroyed before the children of Israel. And the LORD spoke to Manasseh, and to his people: but they would not hearken.” The prophet Isaiah used the word err throughout his writing to refer to the leaders of Israel causing the people to veer off the course God had established for them, the Mosaic Law.
Rather than punish the entire nation of Judah and undo the good that Hezekiah had accomplished, God chose to single out Manasseh in order to bring him to repentance. It says in 2 Chronicles 33:11-13:
Wherefore the LORD brought upon them the captains of the host of the king of Assyria, which took Manasseh among the thorns, and bound him with fetters, and carried him to Babylon. And when he was in affliction, he besought the LORD his God, and humbled himself greatly before the God of his fathers, and prayed unto him: and he was intreated of him, and heard his supplication, and brought him again to Jerusalem into his kingdom. Then Manasseh knew that the LORD he was God.
After Manasseh acknowledged God’s sovereignty and was returned to Jerusalem, he showed evidence of genuine repentance. It says that “he took away the strange gods and the idol out of the house of the LORD” (2 Chronicles 33:15). Manasseh not only stopped practicing idolatry, but he also began to worship the LORD and commanded the people to observe the Mosaic Law (2 Chronicles 33:16). Manasseh’s example of repentance was one of the few seen in the Old Testament, particularly among the kings of Judah and Israel. It could be that his captivity in Babylon was such a horrifying experience that he realized spending eternity in hell was not a good option.
