In 2 Corinthians 4:5–18, Paul reminds us that though we are fragile like jars of clay, we carry the priceless treasure of the gospel. Our weakness reveals that the surpassing power belongs to God, not to us. Though outwardly we waste away, inwardly we are being renewed by God’s grace day by day. This momentary affliction is preparing us for an eternal glory far outweighing it all, as we fix our eyes not on what is seen, but on what is unseen.
