Day 235 Kings with a prayer?

King Asa is sick but does not turn to the Lord. He places sole confidence in the doctors. His infected feet cause him to die. Hezekiah becomes ill and is open to prayer..."Please, O Lord, remember how I have walked before you in faithfulness and with a whole heart, and have done what is good in your sight.” And Hezekiah wept bitterly. His prayer led to his healing. Asa lacked the faith in the Great physician and died. What are we to make of this theologically? Reliance on God's power is not to be ignored...though both Kings had their troubles.
