So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day.
2 Corinthians 4:16
The process of death begins before we even reach physical maturity. The decay of our bodies is inevitable, but the decay of our spirits is not. By God's grace manifested in the death and resurrection of his son, by surrender to his mercy and lordship, the stains of sin are removed from our souls, and we have the promise of resurrection to eternal life in recreated, incorruptible bodies at the final judgment.
