John Chrysostom
Another interpretation suggests that those who are arrogant like mighty waters would have overwhelmed our spirits. Do you perceive the assistance of God? In the face of such trials, He does not permit us to be overwhelmed by despair. God allows hardships to increase, not to drown us, but to deepen our understanding and to reveal His might more vividly. The proud are identified here as adversaries, who, striking with greater force than any torrent or indomitable flood, inflicted no damage upon us; and this is due to the aid of God, the support from on high, the unwavering protection.
