That your faith should not be in the wisdom of men. To be is used here as meaning to consist His meaning, then, is, that the Corinthians derived this advantage from his having preached Christ among them without dependence on human wisdom, and relying solely on the Spirit's influence, that their faith was founded not on men but on God. If the Apostle's preaching had rested exclusively on the power of eloquence, it might have been overthrown by superior eloquence, and besides, no one would pronounce that to be solid truth which rests on mere elegance of speech. It may indeed be helped by it, but it ought not to rest upon it On the other hand, that must have been most powerful which could stand of itself without any foreign aid. Hence it forms a choice commendation of Paul's preaching, that heavenly influence shone forth in it so clearly, that it surmounted so many hindrances, while deriving no assistance from the world. It follows, therefore, that they must not allow themselves to be moved away from his doctrine, which they acknowledge to rest on the authority of God. Paul, however, speaks here of the faith of the Corinthians in such a way as to bring forward this, as a general statement. Let it then be known by us that it is the property of faith to rest upon God alone, without depending on men; for it requires to have so much certainty to go upon, that it will not fail, even when assailed by all the machinations of hell, but will perseveringly endure and sustain every assault. This cannot be accomplished unless we are fully persuaded that God has spoken to us, and that what we have believed is no mere contrivance of men. While faith ought properly to be founded on the word of God alone, there is at the same time no impropriety in adding this second prop, -- that believers recognize the word which they hear as having come forth from God, from the effect of its influence.

That your faith - That is, that your belief of the divine origin of the Christian religion.
Should not stand - Greek, "should not be;" that is, should not rest upon this; or be sustained by this. God intended to furnish you a firm and solid demonstration that the religion which you embraced was from Him; and this could not be if its preaching had been attended with the graces of eloquence, or the abstractions of refined metaphysical reasoning. It would then appear to rest upon human wisdom.
In the power of God - In the evidence of divine power accompanying the preaching of the gospel. The power of God would attend the exhibition of truth everywhere; and would be a demonstration that would be irresistible that the religion was not originated by man, but was from heaven. That power was seen in changing the heart; in overcoming the strong propensities of our nature to sin; in subduing the soul; and making the sinner a new creature in Christ Jesus. Every Christian has thus, in his own experience, furnished demonstration that the religion which he loves is from God, and not from man. man could not subdue these sins; and man could not so entirely transform the soul. And although the unlearned Christian may not be able to investigate all the evidences of religion; although he cannot meet all the objections of cunning and subtle infidels, although he may be greatly perplexed and embarrassed by them, yet he may have the fullest proof that he loves God, that he is different from what he once was; and that all this has been accomplished by the religion of the cross.
The blind man that was made to see by the Saviour John 10, might have been wholly unable to tell how his eyes were opened, and unable to meet all the cavils of those who might doubt it, or all the subtle and cunning objections of physiologists, but of one thing he certainly could not doubt, that "whereas he was blind, he then saw;" John 10:25. A man may have no doubt that the sun shines, that the wind blows, that the tides rise, that the blood flows in his veins, that the flowers bloom, and that this could not be except it was from God, while he may have no power to explain these facts; and no power to meet the objections and cavils of those who might choose to embarrass him. So people may know that their hearts are changed; and it is on this ground that no small part of the Christian world, as in everything else, depend for the most satisfactory evidence of their religion. On this ground humble and unlearned Christians have been often willing to go to the stake as martyrs - just as a humble and unlearned patriot is willing to die for his country. He loves it; and he is willing to die for it. A Christian loves his God and Saviour; and is willing to die for his sake.

That your faith should not stand - That the illumination of your souls and your conversion to God might appear to have nothing human in it: your belief, therefore, of the truths which have been proposed to you is founded, not in human wisdom, but in Divine power: human wisdom was not employed; and human power, if it had been employed, could not have produced the change.

(3) That your faith should not stand in the wisdom of men, but in the power of God.
(3) And he tells the Corinthians that he did it for their great profit, because they might by this know manifestly that the Gospel was from heaven. Therefore he privately rebukes them, because in vainly seeking to be noticed, they willingly deprived themselves of the greatest help of their faith.

That your faith should not stand,.... "Or be in the wisdom of men, but in the power of God". The Spirit of God directed him, and he under his influence chose, and by his assistance pursued this way of preaching, with this view, and for this reason, that faith in Christ, and in the doctrines of his Gospel, which comes by hearing, might not be attributed to the force of human eloquence and oratory; or stand upon so sandy a foundation, as that which might, if that was the case, be puffed away by a superior flow and force of words; but that it might be ascribed, as it ought to be, to almighty power, stand in it, be supported by it, and at last be finished and fulfilled with it.

stand in . . . wisdom of men--rest on it, owe its origin and continuance to it.

That your faith might not be built on the wisdom or power of man, but on the wisdom and power of God.
