51 The confession of the Apostles, for whom by a word of command the raging wind and troubled sea were restored to calm, was an opportunity for you. You might have confessed, as they did, that He is God's true Son; you might have borrowed their very words, Of a truth, this is the Son of God. But an evil spirit of madness is driving you on to shipwreck of your life; your reason is distracted and overwhelmed, like the ocean tormented by the fury of the storm.
