in his time

"He is not deaf, he listens; more than that, he acts. He does not act in the same way whether we pray or not. Prayer exerts an influence upon God's action, even upon his existence.

That is what the word 'answer' means." "The fact that God yields to man's petitions, changing his intentions in response to man's prayer, is not a sign of weakness. He himself, in the glory of his majesty and power, has so willed it."
--Karl Barth
