“So teach us to number our days that we may get a heart of wisdom” (Psalm 90:12). I read a powerful thought this morning in Richard Sibbes’ comments on 2 Corinthians 4:11: “We who live are always being given over to death for Jesus’ sake, so that the life of Jesus also may be manifested in our mortal flesh.” There are no wiser thoughts in this world than judging rightly the condition of earthly things, and the condition of our own hearts in relation to them. Wisdom is seeing the vanity of this world, and our own mortality. We are “earthen vessels”, our mortal bodies are subject to decay and death. The wise person is always keeps in mind the fleeting nature of this life. This wisdom will keep us from setting our affections on things that will not last long. It is the foolishness of youth to put so much emphasis on the appearance of the body. If we have wisdom, the “life of Jesus” will be seen in us. People should see something very different and very compelling in Christians.
