God has given you a prescription for your healing. In Proverbs 4:20-22 God says, "My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of your heart. For they are life unto those that find them, and health to all their flesh." That word health is translated as medicine, remedy, and cure. So, God has already made a way for you out of that sickness. But, you have your part to play in receiving your healing. In the natural if you went to a doctor for a health problem and he wrote you out a prescription you would look to get better. Also you would agree that you had your part, taking the medicine is your responsibility. And just as that medicine has ingredients in it that aids the body, God's word has healing power in it. But, you have to take it.
How does it work, what you feed into your spirit feeds your flesh. In Proverbs 14:30 it says, "A sound heart is the life of the flesh: but envy the rottenness of the bones." Your spirit gives life to your flesh and according to what you put in it will determine whether you get healed or stay sick, "The spirit of a man will sustain his infirmity" (Proverbs 18:14). Notice his word is life, the very life of God is in his word (John 1:1). It's a feeding process, remember Jesus said, "It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God" (Matthew 4:4). What is bread, nourishment for your body. You take it in and the nutrients are sent throughout the body. So likewise, when you take God's word in the life in it is sent throughout the body and gets rid of any sickness and disease. Like in Romans 8:11, "But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ shall also quicken your mortal bodies by the Spirit that dwelleth in you." That word quicken means to make alive, give life, and vitalize(to fill with life, vigor, energy). God's word is spirit and life(John 6:63), and that spirit and life will quicken your body. But, notice it says to keep the word in your heart(spirit) so give it some time. I gave it some time and I got my healing and you can too.
