Paul reminds believers that Christ’s return will come suddenly and without warning, urging them to stay awake, alert, and living as children of the light—faithful, loving, and full of hope. He calls Christians to be prepared not by fear but by active trust in God—repenting, believing, and living out their faith daily while waiting for His return. Our hope and salvation in Christ should move us to live each day as if it were our last, reflecting His light through love, service, and unwavering faith in God’s promises.
