Two trains of thought come from this verse. The first is that our days are numbered and fleeting…and we need to make the most of every minute. All our days here on earth were ordained by God before any of them ever came to be, (Psalm 139:16) and we need to use each one to its fullest potential for His glory and our good. Secondly, we may think we’re the boss of ourselves…planning our way and course of action, but God is really the One who is directing our steps. (Proverbs 16:9 & Proverbs 20:24) And the sooner we honestly consider just how short out lifetime is, we can learn not to take any day for granted.
