"In the world you will have tribulation. But take heart; I have overcome the world."
Jesus doesn't promise His followers a tribulation-free life; He promises the opposite, plainly, without softening it. But He attaches courage to a completed fact, not a future hope: 'I have overcome' is already accomplished, past tense, not pending. Whatever tribulation you're facing today, your courage doesn't depend on the outcome being uncertain. It rests on a victory already secured. Take heart today not because your circumstances have improved, but because the war behind your circumstances has already been won.
Jesus, You have already overcome the world. Let that finished victory give me courage in today's trouble. Amen.
