I recall the passage in the letter to the Hebrews in which we are reminded that Christ has already done everything for us. It speaks of the Christ who "offered for all time a single sacrifice for sins" (Hebrews 10:12). And yet the church teaches, and our experience of faith confirms, that Christ continues to be with us and to pray for us. The paradox may be unraveled, I think, if we remember that when human beings try to "do everything at once and for all and be through with it," we court acedia, self-destruction and death. Such power is reserved for God, who alone can turn what is "already done" into something that is ongoing and ever present. It is a quotidian mystery.
