Wisdom is better than weapons of war, but it is also fragile. In this sermon, we confront the sobering truth that in a broken world, a little folly can outweigh a lifetime of wisdom. Drawing from Ecclesiastes 10 and the story of Moses in Numbers 20, we see how quickly wise decisions can be undermined by a single foolish act, and how the temporal promises of wisdom can be upended by foolish leaders. But this is not a call to despair. It’s a call to vigilance, humility, and hope. True wisdom, rooted in Christ, leads us beyond the chaos of life under the sun and into the unshakeable promises of God.
