He may delay because it would not be safe to give us at once what we ask: we are not ready for it. To give ere we could truly receive, would be to destroy the very heart and hope of prayer, to cease to be our Father. The delay itself may work to bring us nearer to our help, to increase the desire, perfect the prayer, and ripen the receptive condition.
God’s Best
C S Lewis
We are not necessarily doubting that God will do the best for us; we are wondering how painful the best will turn out to be.
