Below are two excerpts from AW Tozer, “The Freedom of the Will”, originally published in The Alliance Witness and later included as chapter 7 in That Incredible Christian (which is available in full in PDF at this external link).
So highly does God regard His handiwork that He will not for any reason violate it. For God to override man’s freedom and force him to act contrary to his own will would be to make a mockery of the image of God in man. This God will never do.
Our Lord Jesus looked after the rich young ruler as he walked away, but He did not follow him or attempt to coerce him. The dignity of the young man’s humanity forbade that his choices should be made for him by another. To remain a man he must make his own moral choices; and Christ knew this and permitted him to go his own chosen way. If his human choice took him at last to hell, at least he went there a man; and it is better for the moral universe that he should do so than that he should be jockeyed to a heaven he did not choose, a soulless, willess automaton.
God will take nine steps toward us, but He will not take the tenth. He will incline us to repent, but He cannot do our repenting for us. It is of the essence of repentance that it can only be done by the one who committed the act to be repented of. God can wait on the sinning man; He can withhold judgment; He can exercise long-suffering to the point where He appears “lax” in His judicial administration; but He cannot force a man to repent. To do this would be to violate the man’s freedom and void the gift God originally bestowed upon him.
Where there is no freedom of choice there can be neither sin nor righteousness, because it is of the nature of both that they be voluntary. However good an act may be, it is not good if it is imposed from without. The act of imposition destroys the moral content of the act and renders it null and void.
For an act to be sinful the quality of voluntariness must also be present. Sin is the voluntary commission of an act known to be contrary to the will of God. Where there is no moral knowledge or where there is no voluntary choice, the act is not sinful; it cannot be, for sin is the transgression of the law and transgression must be voluntary.
Dr Tozer concludes:
But someone may ask, “When we pray ‘Not my will, but Thine be done,’ are we not voiding our will and refusing to exercise the very power of choice which is part of the image of God in us?” The answer to that question is a flat No, but the whole thing deserves further explanation.
No act that is done voluntarily is an abrogation of the freedom of will. If a man chooses the will of God he is not denying but exercising his right of choice. What he is doing is admitting that he is not good enough to desire the highest choice nor is he wise enough to make it, and he is for that reason asking Another who is both wise and good to make his choice for him. And for fallen man this is the ultimate use he should make of his freedom of will.
Tennyson saw this and wrote of Christ,
Thou seemest human and divine,
The highest, holiest manhood, Thou;
Our wills are ours, we know not how;
Our wills are ours, to make them Thine.
There is a lot of sound doctrine in these words—”Our wills are ours, to make them Thine.” The secret of saintliness is not the destruction of the will but the submergence of it in the will of God.
The true saint is one who acknowledges that he possesses from God the gift of freedom. He knows that he will never be cudgled into obedience nor wheedled like a petulant child into doing the will of God; he knows that these methods are unworthy both of God and of his own soul. He knows he is free to make any choice he will, and with that knowledge he chooses forever the blessed will of God.
From That Incredible Christian, I also highly recommend chapter 6, "Faith’s Foundation Is God” (also available online here).
Many of AW Tozer’s books can be found online for free. Here are two of my other favorites (external links):
