In Genesis 20:17, Abimelech and his entire family got a plague because Abimelech took Abraham's wife Sarah. The King went contrary to God's word and opened himself up to demonic attacks. By the grace of God, when Abimelech changed his mind and returned to God's word, he was healed. Exodus 15:26 says that whoever follows God's word experiences healing even if as a result of their rebellion, they had become sick. If you've forgotten the ways of the Lord and sickness has accessed your body, be healed right now in Jesus name.
