Analysis of It’s not about the body

It’s not about this body that’s subject to decay.
but it’s about the soul that will never fade away.
This body’s getting older and does not function well
and upon its limitations my mind began to dwell.

Then to me, “Fear not,” I heard God’s Holy Spirit say,
“Though your body shall die your soul will soar away
and will rise victorious above this earthly plain
ascending into heaven where there shall be no more pain.”
