Matthew 4:11

Then the devil having exhausted all his artifices, left hem for a time, as St. Luke remarks; whence we are to learn, that after we have resisted with success, we are not to think ourselves secure, but avail ourselves of the truce to return thank to God for the victory, and to prepare for fresh combats, especially by fortifying ourselves with the bread of angels in the holy communion. by example he has taught us how to fight and to conquer. The struggle may be painful; but angels, as well as God, witness our struggle, ready to crown our victory. (Haydock)
