Things Don't Look So Good...Wait Look Closer!
Dont be discouraged by your failing physical body. It is inevitable because from the dust we were formed and to the dust we must return. The process is sometimes painful to watch and/or endure. However, the inner man having been transformed by the power of Christ is being renewed daily instead of decaying.
2 Corinthians 4:16 AMP
Therefore we do not become discouraged (utterly spiritless, exhausted, and wearied out through fear). Though our outer man is [progressively] decaying and wasting away, yet our inner self is being [progressively] renewed day after day.
