I always figured medical treatment was like the old story about the man who was caught in a flood. He climbed up on his roof and prayed to God to save him from the flood. As the waters rose higher, his neighbor came by in a rowboat and offered to let him get in. The man said, "No thanks. I'm certain God will deliver me."
The water got deeper, and he continued praying. A man in a motorboat came by and shouted, "Get in! You're going to drown if you stay there!" The man on the roof shouted back, "No, God will save me! I'm sure of it!"
As the waters climbed up his body, a helicopter came by and threw down a ladder. But the man refused, insisting that God would save him if he just believed. The helicopter flew away, and the man drowned.
When he got to Heaven, he confronted God and said, "I always believed that if I prayed and trusted you, you would help me and take care of me. Why did you let me drown instead of saving me?"
God answered, "I sent you two boats and a helicopter. Why didn't you get into any of them?"
If a person is rejecting medical treatment because they want to pray for a miracle to heal them instead, maybe they should consider that God ALREADY sent the miracle by allowing mankind to be smart enough to figure out medical treatment.
