The human body is a wondrous creation. It did not come by accident but was planned by an omniscient and omnipotent Creator. The body has a blood supply that creates antibodies that help fight off infections. In fact, when a doctor suspects infection he has a blood test done to see if the white blood cell count is high. If it is the white blood cells are already at work in the natural healing process, but the doctor decides if antibiotics are needed or if they think the body can heal itself if given time. In many cases it can, because our Creator made it so.
Sometimes in our physical bodies one part will attack another part when it is ailing….as in Rheumatoid Arthritus…where the rheum, the lining of the joints, is attacked and made painful by the body itself.
The church, the body of Christ is also amazing. Christ’s blood cleanses. Sometimes though, some of the members attack one another and cause extreme pain and sorrow. We are bought with Christ’s blood and it runs through the body (church) cleansing us from sin, after we have entered His body through faith, repentance, confession of Him and baptism, which is the initial cleansing that puts us in a right relationship with Him and makes us Christians. 1 John 1:6-7 “If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.”
If the spiritual body of Christ is having infections…(i.e. false teachings, wrong application of Scripture, etc.) maybe a gentler means should be used first and time should be given for the body to heal itself…instead of the wrong-doers being picked to pieces and attacked publically by its own body (by other members).
