It is quite amusing the faith we put in men to heal us but have trouble believing that God can do it without us if He chooses. God help us in our unbelief. We need to realize that God is the one who heals. He uses various means to accomplish His work. Most often He uses doctors and nurses and we are thankful for their dedication.
Many people call the physician first and then begin to pray.
I would suggest that we pray first. Give God a chance to work a miracle. You'll be surprised at how much money you'll save. You will have more to put in God's work of building His Kingdom. As we read His Word we find that He promises to be with us and give us power and strength to meet every need in our lives.
