"The heart of the issue is the issue that hurt the heart."
We are totally dependent on God who is the controlling force of the spirit and power of life. The spirit keeps the soul conscious.
The soul is our psyche. That is our heart/(mind), consciousness, emotions and our awareness of self. It is where we have the inner being and source of earthly and eternal life.
The body is our physical complete person of flesh covering the dwelling place for the spirit and soul. Our bodies are the external human nature in the physical.
