One of the most frightening books I own is Christian Prayer: The Liturgy of the Hours.
As just one example, this if from today's Morning Prayer:
Help us to bear witness to you by following [Jesus'] example of suffering and make us worthy to share in his resurrection.
Imagine for a moment what it would be like if God said, "You asked for it, you got it!"
Yet I blithely asked exactly this of God this morning, and in a little while will again say, "Amen," when the priest offers the same prayer as the collect of Palm Sunday Mass.
