John Chrysostom
Why did the Lord choose not to command the winds to calm down, but instead reached out His hand to uphold Peter? It was essential for Peter to exhibit faith. When we falter, divine intervention halts. Therefore, to illustrate that it was not the power of the wind but Peter's wavering faith that caused the turmoil, the Lord questioned, ‘O ye of little faith, why didst thou doubt?’ Had his faith remained steadfast, he could have easily defied the wind. Thus, the Lord, while supporting Peter, refrained from silencing the wind to demonstrate that genuine faith renders the wind harmless.
