“So he went down and dipped in the Jordan seven times, as the prophet had instructed. His skin became as smooth as a young child’s and he was healed.”
2 Kings 5.14
Naaman, the Syrian army commander, first balked at the prophet Elias’s command. Only when he decided to obey was he healed of his disease.
Just as there is power in prayer for the Christian because God answers, there is power in obedience for the sinner because God forgives. When at some moment of obedience in your life did you see God’s power?
