In New Testament terms, healing is holistic in that it encompasses spirit, soul, and body (1 Thessalonians 5:23). In today’s terms we would say spiritual, mental and physical. Some illnesses are psychosomatic, in that thoughts can have adverse or beneficial effects on the body.
Divine Healing is quite different. I am not referring to the use of scriptures to encourage positive thoughts, which is a sort of Bible-based psychology. Nothing wrong with that, just that it cannot bring about miraculous changes. Jesus did not command the paralyzed man to Think Positive and take up his bedroll and walk; or heal the withered arm of another by telling the man to envision himself doing so. It was the Lord’s words of authority and the power of the Spirit of God flowing through him to others that brought healing.
Do you know what it’s like to preach God’s promises in a meeting and then invite the sick to come forward so that you can lay your hands on them in the name of the Lord Jesus and see them healed by the power of God — every time knowing that but for the power of God within you all you can give them is fingerprints? It is terrifying! It’s all care and no responsibility, because in most people there are factors about which you know absolutely nothing.
Regardless, you assure all present that it is God’s will to heal the sick, generally speaking, and then proceed, dismissing thoughts as to why some are not. Just why the Lord heals some and not others is not our business. This is not an excuse but a sanity saver. Many will “recover” — get well — as Jesus promised, a few will receive miracles of healing on the spot.
There’s nothing mystical about such healings except that they are supernatural in origin and physical in outcomes. Some will prove undeniable (Acts 4:13-16) and others may be attributable to a combination of faith and natural factors such as dietary measures. We have nothing to prove: our duty is to pray and leave the results to God.
Your body wants you well and has inbuilt biological self-recovery systems. Doctors also want you well, their professional oath is “Do No Harm.” God wants you well: His covenant states so in no uncertain terms (Exodus 15:26). Prophetically, God promised healing along with forgiveness in the sufferings of the Messiah in Isaiah 53, and again as an accomplished fact in 1 Peter 2:24.
Finally, Jesus proved that God wants you well by spending much of his time healing people — at times “all who came to him”. We do know who doesn’t want you well! (Acts 10:38) Finally, if your pastor or priest does not believe that God heals today — go straight to your doctor and ask for medical help! Far better a doctor who believes in medicine than a minister who doesn’t believe in the Bible.
