The Bible's most comforting passages were rarely written from comfortable places. Psalm 23 was likely composed late in David's life, after he had been hunted, betrayed, and bereaved. Lamentations was written inside the ruins of Jerusalem. Paul wrote the “my grace is sufficient” promise from prison. The peace these verses offer is not the absence of trouble — it is a peace that has walked through trouble and come out still able to speak.
Read slowly. One verse a day is enough.
