Begin to rejoice in the Lord, and your bones will flourish like an herb, and your cheeks will glow with the bloom of health and freshness. Worry, fear, distrust, care-all are poisonous! Joy is balm and healing, and if you will but rejoice, God will give power.
Your soul is your mind, your will and your emotions. When the Word gets rooted in there and begins to change your mind, it begins to heal your emotions and turn your will away from self-will and onto doing the will of God.
Healing was a miraculous sign gift to be used for special purposes. It was not intended as a permanent way to keep the Christian community in perfect health. Yet today most charismatics teach that God wants every Christian well. If that is true, why does God allow Christians to get sick in the first place?
We never see the gift gof healing) being used at random in the churches. It is a gift associated only with Christ, the twelve (plus Paul), the seventy, and some who were intimate co-workers with the apostles.
