"All healing takes place from the inside out" is what I refer to as The Golden Rule of Healing. We see this phenomenon take place in the healing of cuts and fractured bones. But our bodies are not the only part of us that are in need healing . The fact of the matter is our existence consists not only of an outer physical  life but also an inner spiritual life.  

Jesus taught, ".. I have come that they may have life, and have it to the full." [John 10:10]. The life to the full of which he speaks begins with healing of the inner life. And since all healing takes place from the inside out, the end result is total healing  and wholeness.
