2 Corinthians 4:16-18
In these three verses, the concept of faith continues. For us, most important is "even though the outward man is perishing, yet the inward man is being renewed day by day." What is Paul describing here? It is the process of dying and renewing. The outer man—the shell, the body—is decaying. What causes it to decay? In the context, it is the trials of life—the perplexities, the afflictions, the persecutions, the solitude.
The outer man 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 so energized that Deuteronomy 34:7 says that at the age of 120, his natural forces, his vigor, were not abated.
We are aware of this principle because transformations of energy take place all around us every day. Energy from the sun strikes the earth, and plants transform that energy into leaves, flowers, and fruit. The energy of a river can be transformed into electricity, which in turn is transformed into light and heat—one form of energy turned into another.
Paul is saying that, if we yield to God, though it expends our physical energy, it will be transformed into Christ's likeness. We will become like Christ. The key is to expend our energy in doing the will of God, otherwise the right fruit will not be produced. Even though we have to sacrifice ourselves in doing it—we give up our time, our energy, our resources—what will be produced is spiritual energy. Our physical energy will be transformed into the beauty and power of the spirit until death, and then the resurrection will release the full power of the spirit. All along the way, the fruit of that process will be true conviction because we will know God.
We Christians have this treasure in earthen vessels. If we submit to God's discipline—expending ourselves and yielding to God in the little things day by day—we will see our conviction grow. Then, if people call us into account, we will not be worried because we know absolutely—because we have lived it. This is the kind of faith God wants us to have.

Conviction, Moses, and Us
Fellowship with God, established through Christ's sacrifice, must be built upon and renewed daily, since human attitudes, faith, love, joy, and peace constantly fluctuate. This renewal involves a process of dying and renewing: the outward man, the body, decays through the trials of life the afflictions, persecutions, and perplexities while the inward man is strengthened through those same trials. Physical energy spent in doing God's will is transformed into spiritual energy, producing Christ's likeness and true conviction, until death and the resurrection release the spirit's full power. This transformation begins now in the mind, by seeking invisible, eternal things rather than temporary, physical ones. Despite many hardships, Paul relied on God and refused discouragement, holding to God's way even unto death.
