Life is not stationary. Seconds, minutes, hours, days, weeks, months, and years all tick away at the same clip for everyone. No age-group can be isolated. None of us can settle into infancy, youth, middle age, or old age. We all grow older, and, incidentally, it is an exciting thought if the accent is on growing. "Though our outward man perish," said Paul, "yet the inward man is renewed day by day" (2 Cor. 4:16; italics added).
