God says that He is your Doctor Ė your Healer Ė in Exodus 15:26. Like all doctors, God gives a prescription. You can find it in Proverbs 4:20-22:
ďMy son, attend to my words, incline your ear to my sayings. Let them not depart from your eyes; keep them in the midst of your heart. For they are life to those who find them, and health to all their flesh.Ē
If your flesh has stomach trouble, blood disorders, diabetes, cancer, etc., God has provided medicine for it Ė His word. He sent his word and healed them (Psalm 107:20). The only thing with any prescription is that you have be faithful to take it. Otherwise the medicine doesnít do what it was created to do.
I have met Christians who have been willing to lose weeks of work, spend fortunes on medications, go through complicated surgery, etc., with no definite promise that they will be healed as a result. Yet these same people would probably not even walk across the street to go somewhere where the sick are being ministered to in the name of Jesus so that they can hear word of God, which brings healing. Iíve never understood that and still donít understand it. If people would exercise the same diligence in the things of the Spirit that they exercise in taking natural remedies and surgeries, weíd see a lot more people healed supernaturally. Most missionaries agree that the easy availability of quality health care here has resulted in many Christians never learning to exercise their faith for healing, whereas the lack of such care overseas motivates people to be very, very serious in seeking healing through Godís direct means. So they see a lot more healings and miracles.
I donít preach against medicine, but doesnít it make sense, if youíre going to take manís imperfect medicine (which often has side effects), that you would be just as diligent to take Godís medicine? Hear the word that He sent to heal you! Godís medicine has only good side effects! Not only that, but unlike manís medicine, His is health to all your flesh Ė it can solve any illness youíre dealing with.
However, you have to take it as prescribed. If you only took your natural pills once every 2 weeks, do you think youíd get the right results? Godís instructions are to pay close attention to His words and keep them in your heart. Only when you do that have you really followed His prescription. But if you follow his prescription, it will work for you! God guarantees its success Himself!
