If God can create, he can certainly heal the creatures which he created. God reveals himself as our healer throughout the Bible. Possibly the earliest healing in the Bible is when Abraham prayed for Abimelech’s household and God healed them (Genesis 20:17). God promised healing to Israel in Exodus 15:26 in return for their obedience. There is also our responsibility for the healing of those we have injured (Exodus 21:19). Numbers 12 and Deuteronomy 28 reveal that one cause of disease can be sin. And in Deuteronomy 32:39 God reveals himself as healer in a manner than no man can. So, when Jesus healed even what we term today as mental illnesses (Mark 1:21-28) it was a sign of his divinity. Though he does not always heal immediately, God’s promise of healing has not changed.
