The waves that beat into the disciples' boat and fill it during the sudden storm on the Sea of Galilee terrify them, yet Jesus sleeps peacefully through it because He completely trusts the Father's care and knows He has God-given power over winds and sea. When He commands the sea, "Peace, be still!" the Greek phrase means "be muzzled" or "gagged," as though the storm were a maniac that had to be bound and restrained. Mark indicates He addresses not merely a meteorological force but a being behind it. Christ treats the storm and sea as antagonistic, rebelling forces, since conflict and disorder in nature trace back to Satan, the author of confusion, whose works Jesus came to overcome and destroy. His word alone is enough to calm them, just as it commands demons to leave the possessed. The miracle contrasts the disorder of nature with the power, order, and peace of the Creator (Psalm 89:9), who long ago shut in the sea with doors and said, "This far you may come but no farther" (Job 38:8, 11). The waves of the world still rage against Christ's disciples, but they will never be overwhelmed because Christ is in them (Psalm 46:1-3; 93:3-4). The disciples' fear shows that faith and fear cannot coexist, for fear paralyzes faith.
