Praying these bible healing scriptures for patients is encouraged because God says in His Word in Jeremiah 33:3 “Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.”
In Hebrews 4:12, we read that God's Word is alive and powerful, sharper than a two-edged sword. When we pray the scriptures, we are coming into agreement with God, and His power is released to answer our prayers.
