What? Know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? (1 Corinthians 6:19).
As a believer in Christ, your body is the temple of the Holy Ghost. But you’re the custodian or caretaker of your body. Thus, you have the right to determine what happens to, and in, your physical body.
As the watchman over your body, it’s your responsibility to give no place to sickness in your body, for you stand to give account to God for whatever you allow or disallow in your physical body. You’re to permit in your body only those things that are consistent with the Word of God for your life. That means you’re to give no place to sickness, disease or infirmity in your body!
Sickness cannot stay in your body if you don’t allow it. Your body can only get sick when you endorse sickness, for until you endorse it, it’s nothing but a mirage. No wonder the Bible says they that dwell in Zion shall not say “I am sick” (Isaiah 33:24). So as one who’s born again refuse to be sick. Take charge and rule over your body with the Word of God; refuse to yield your body to sickness.
When you see the symptoms of sickness in your body, refuse to consider them for they’re nothing but lying vanities. They only become real when you say they are, because what you say is what you get. This is what the Word of God teaches in Mark 11:23. “…he shall have whatsoever he saith.” Therefore, never say “I have headaches.” or “I have the flu,” or “I’ve got migraines,” or “I have diabetes”; never endorse sickness.
