2 Corinthians chapter 4 and verse 16 says “Therefore we do not lose heart. Even though our outward man is perishing, yet the inward man is being renewed day by day”.
In this and the next 2 verses of this Bible reference, the concept of faith continues. For us, most important is “even though outwardly our body may be perishing as we age and as we go through the challenges of life, at work and at play, the inward person is being renewed day by day.” What is Paul describing here? It is the process of dying and renewing. The outer person—the shell, the body—is slowly getting weaker and decaying ( I know , cheerful aren’t I today!). What causes it to decay? In the context of these verses, it is the trials of life—the perplexities, the afflictions, the persecutions, the battle. Some call it in contemporary language, “the slog” or the “rat race”.
The wonder of the Christian life with God is that the outer person is decaying through the trials of life, while the inner man is being strengthened through the same trials!
The energy of the body is spent in doing God’s will, and it is being transformed into the energy of the spirit. Moses was energized in exactly this way and so Deuteronomy 34:7says that at the age of 120, his natural forces, his vigour, were not weakening at all.
It is one of those miracles so often overlooked as yet more evidence of God’s true existence and influence on a human life that follows Him in the way described in the Bible. There are many who may claim to be Christian on application forms and the like but far less who actually follow Christ in the way He taught in the Bible and it seems to me that it is only those who truly die to self as Paul also describes it in his writings found in Scripture , who experience this daily inward power and renewal.
Have a good day
