Prayer has its great end when it lifts us to be more conscious and more sure of the gift than the need, of the grace than the sin. As petition rises out of need or sin, in our first prayer it comes first; but it may fall into a subordinate place when, at the end and height of our worship, we are filled with the fullness of God. "In that day ye shall ask Me nothing." Inward sorrow is fulfilled in the prayer of petition; inward joy in the prayer of thanksgiving. And this thought helps to deal with the question as to the hearing of prayer, and especially its answer. Or rather as to the place and kind of answer. We shall come one day to a heaven where we shall gratefully know that God's great refusals were sometimes the true answers to our truest prayer. Our soul is fulfilled if our petition is not.
