God does not ask you to love the cross with the will of the flesh. Since the flesh is subject to sin and corruption, all that proceeds from it is perverted and, of itself, cannot be submissive to the will of God and his crucifying law. It was this human will our Lord referred to in the Garden of Olives when he cried out, "Father, let your will be done, not mine." If the lower part of Christ's human nature, although so holy, could not love the cross continuously, then with still greater reason will our tainted nature reject it.
--St. Louis de Montfort, Letter to the Friends of the Cross
