No one can really embrace the Christian asceticism mapped out in the New Testament unless he [or she] has some idea of the positive, constructive function of self-denial. The Holy Spirit never asks us to renounce anything without offering us something much higher and much more perfect in return … The function of self-denial is to lead to a positive increase of spiritual energy and life. The Christian dies, not merely in order to die but in order to live. And when he [or she] takes up his cross to follow Christ, the Christian realizes, or at least believes, that he is not going to die to anything but death. The Cross is the sign of Christ’s victory over death. The Cross is the sign of life. It is the trellis upon which grows the Mystical Vine whose life is infinite joy and whose branches we are. If we want to share the life of that Vine, we must grow on the same trellis and must suffer the same pruning.
