Have confidence in the efficacy of prayer

"Prayer is not, in fact, a force having its first principle in us; it is not an effort of the human soul, trying to do violence to God in order to make Him change His providential dispositions. Such a manner of speaking, which is used occasionally, is a metaphorical, human way of expressing oneself. In reality, the will of God is absolutely immutable, but this superior immutability is precisely the source of the infallible efficacy of prayer.

Fundamentally it is very simple in spite of the mystery of grace involved in it. We have here a combination of the clear and the obscure that is most captivating and beautiful. First of all, we shall consider what is clear: true prayer is infallibly efficacious because God, who cannot contradict Himself, has decreed that it should be. This is what the contemplation of the saints examines profoundly.

Prayer is precisely a cause ordained to produce this effect: the obtaining of the gifts of God. All creatures exist only by the gifts of God, but the intellectual creature alone can realize this. Existence, health, physical strength, the light of the intellect, moral energy, success in our enterprises, all is the gift of God; but especially is this true of grace which leads to salutary good, causes it to be accomplished, and gives strength to persevere. Grace and, even more, the Holy Ghost who has been sent to us and who is the source of living water, is the gift par excellence which Christ spoke of to the Samaritan woman: 'If thou didst know the gift of God, and who He is that saith to thee: Give Me to drink; thou perhaps wouldst have asked of Him, and He would have given thee living water. . . . Whosoever drinketh of this water shall thirst again; but he that shall drink of the water that I will give him shall not thirst forever. But the water that I will give him shall become in him a fountain of water, springing up into life everlasting.'

Therefore prayer is necessary to obtain the help of God, as seed is necessary for the harvest. Even more, though the best seed, for lack of favorable exterior conditions, can produce nothing, though thousands of seeds are lost, true, humble, trusting prayer, by which we ask for ourselves what is necessary for salvation, is never lost. It is heard in this sense, that it obtains for us the grace to continue praying.

The efficacy of prayer well made is infallibly assured by Christ: 'Ask, and it shall be given you: seek and you shall find: knock, and it shall be opened to you. . . . And which of you, if he ask his father bread, will he give him a stone? Or a fish, will he for a fish give him a serpent? . . . If you then, being evil, know how to give good gifts to your children, how much more will your Father from heaven give the good Spirit to them that ask Him?' To the apostles He also says: 'Amen, amen I say to you: if you ask the Father anything in My name, He will give it to you. Hitherto you have not asked anything in My name.' Prayerful souls ought more than all others to live by this doctrine, which is elementary for every Christian; by living it, one discovers its depths.

Let us, therefore, have confidence in the efficacy of prayer. It is not only a human force which has its first principle in us; the source of its efficacy is in God and in the infinite merits of Christ. It descends from an eternal decree of love, it reascends to divine mercy. A fountain of water rises only if the water descends from an equal height. Likewise when we pray, it is not a question of persuading God, of inclining Him to change His providential dispositions; rather we have only to lift our will to the height of His in order to will with Him in time what He has'decided from all eternity to grant us. Far from tending to bring the Most High down toward us, "prayer is a lifting up of the soul toward God,' as the fathers say. When we pray and are heard, it seems to us that the will of God inclines toward us; on the contrary, it is ours which rises; we begin to will in time what God willed for us from all eternity."
