The kings of Israel illustrate the fact that our free will determines our righteousness.
As an example, Asa was a righteous king who had a son, Jehosaphat, who followed in his ways (2 Chronicles 15:17; 2 Chronicles 17:1-3). Jehosaphat had a son whose name was Jehoram, who did not follow the ways of his father and was very wicked (2 Chronicles 21:12). Jehoram's son, Ahaziah, was also wicked in God's sight (2 Chronicles 22:3-4).
As we can plainly see from the above accounts, a good king had a good son. A good king had a bad son, and a bad king had a bad son, illustrating the fact that all of us have the God-given ability to choose to either serve God or serve Satan (Joshua 24:14-15).
As we journey through this earthly existence, we need to seriously think about the choices we make and how those choices impact our lifestyle and relationship with God.
