I know this thread on prayer isn’t all that recent, but rather than starting a new thread, I would rather add to this thread a bit of George Macdonald wisdom I freshly ran across today regarding the efficacy of prayer. Keep in mind his conversational “query-answer” writing style as you read this. The extra paragraph breaks help call attention to that.
Excerpt from George Macdonald’s unspoken sermon (2nd series) “The Word of Jesus’ Word on Prayer”
As to the so-called scientific challenge to prove the efficacy of prayer by the result of simultaneous petition, I am almost ashamed to allude to it. There should be light enough in science itself to show the proposal absurd. A God capable of being so moved in one direction or another, is a God not worth believing in—could not be the God believed in by Jesus Christ—and he said he knew. A God that should fail to hear, receive, attend to one single prayer, the feeblest or worst, I cannot believe in; but a God that would grant every request of every man or every company of men, would be an evil God—that is no God, but a demon. That God should hang in the thought-atmosphere like a windmill, waiting till men enough should combine and send out prayer in sufficient force to turn his outspread arms, is an idea too absurd. God waits to be gracious not to be tempted. A man capable of proposing such a test, could have in his mind no worthy representative idea of a God, and might well disbelieve in any: it is better to disbelieve than believe in a God unworthy.
‘But I want to believe in God. I want to know that there is a God that answers prayer, that I may believe in him. There was a time when I believed in him. I prayed to him in great and sore trouble of heart and mind, and he did not hear me. I have not prayed since.’
How do you know that he did not hear you?
‘He did not give me what I asked, though the weal of my soul hung on it.’
In your judgment. Perhaps he knew better.
‘I am the worse for his refusal. I would have believed in him if he had heard me.’
Till the next desire came which he would not grant, and then you would have turned your God away. A desirable believer you would have made! A worthy brother to him who thought nothing fit to give the Father less than his all! You would accept of him no decision against your desire! That ungranted, there was no God, or not a good one! I think I will not argue with you more. This only I will say: God has not to consider his children only at the moment of their prayer. Should he be willing to give a man the thing he knows he would afterwards wish he had not given him? If a man be not fit to be refused, if he be not ready to be treated with love’s severity, what he wishes may perhaps be given him in order that he may wish it had not been given him; but barely to give a man what he wants because he wants it, and without farther purpose of his good, would be to let a poor ignorant child take his fate into his own hands—the cruelty of a devil. Yet is every prayer heard; and the real soul of the prayer may require, for its real answer, that it should not be granted in the form in which it is requested.
…and then from the very next sermon in the same series; “Man’s Difficulty Concerning Prayer”
‘How should any design of the All-wise be altered in response to prayer of ours!’
How are we to believe such a thing?
By reflecting that he is the All-wise, who sees before him, and will not block his path. Such objection springs from poorest idea of God in relation to us. It supposes him to have cares and plans and intentions concerning our part of creation, irrespective of us. What is the whole system of things for, but our education? Does God care for suns and planets and satellites, for divine mathematics and ordered harmonies, more than for his children? I venture to say he cares more for oxen than for those. He lays no plans irrespective of his children; and, his design being that they shall be free, active, live things, he sees that space be kept for them: they need room to struggle out of their chrysalis, to undergo the change that comes with the waking will, and to enter upon the divine sports and labours of children in the house and domain of their Father. Surely he may keep his plans in a measure unfixed, waiting the free desire of the individual soul! Is not the design of the first course of his children’s education just to bring them to the point where they shall pray? and shall his system appointed to that end be then found hard and fast, tooth-fitted and inelastic, as if informed of no live causing soul, but an unself-knowing force—so that he cannot answer the prayer because of the system which has its existence for the sake of the prayer? True, in many cases, the prayer, far more than the opportunity of answering it, is God’s end; but how will the further end of the prayer be reached, which is oneness between the heart of the child and of the Father? how will the child go on to pray if he knows the Father cannot answer him? Will not may be for love, but how with a self-imposed cannot? How could he be Father, who creating, would not make provision, would not keep room for the babbled prayers of his children? Is his perfection a mechanical one? Has he himself no room for choice—therefore can give none? There must be a Godlike region of choice as there is a human, however little we may be able to conceive it. It were a glory in such system that its suns themselves wavered and throbbed at the pulse of a new child-life.
