St. Athanasius

If we were to keep the imminence of our death in mind, we would never give in to sin, and we would forgive every person who offended us. 2

Devils take great delight in fullness, and drunkeness, and bodily comfort. Fasting possesses great power and it works glorious things. To fast is to banquet with angels. 3
