The stronger the soul and the flesh, the more fruitful the struggle and the richer the final harmony. God does not love weak souls and flabby flesh. The Spirit wants to have to wrestle with flesh which is strong and full of resistance. It is a carnivorous bird which is incessantly hungry; it eats flesh and, by assimilating it, makes it disappear.
Struggle between flesh and the spirit, rebellion and resistance, reconciliation and submission, and finally - the supreme purpose of the struggle - union with God: this was the ascent taken by Christ, the ascent which he invites us to take as well, following his bloody tracks."
