Did not I tell thee? He reproves Martha's distrust, in not forming a hope sufficiently vigorous from the promise which she had heard. It is evident from this passage, that something more was said to Martha than John has literally related; though, as I have suggested, this very thing was meant by Christ, when he called himself the resurrection and the life Martha is therefore blamed for not expecting some Divine work. If thou believe. This is said, not only because faith opens our eyes, that we may be able to see the power of God shining in his works, but because our faith prepares the way for the power, mercy, and goodness of God, that they may be displayed towards us, as it is said, Open thy mouth wide, and I will fill it, (Psalm 81:10.) In like manner, unbelief, on the other hand, hinders God from approaching us, and may be said to keep his hands shut. On this account it is said elsewhere, that Jesus could not perform any miracle there on account of their unbelief, (Matthew 13:58.) Not that the power of God is bound by the caprice of men, but because, as far as they are able, their malice opposes the exercise of that power, and therefore they do not deserve that it should be manifested to them. Frequently, indeed, does God overcome such obstacles; but yet, whenever he withdraws his hand, so as not to assist unbelievers, this is done because, shut up within the narrow limits of their unbelief, they do not allow it to enter. Thou shalt see the glory of God. Observe, that a miracle is called the glory of God, because God, displaying in it the power of his hand, glorifies his name. But Martha, now satisfied with Christ's second declaration, permits the stone to be removed. As yet she sees nothing, but, hearing the Son of God, not without a good reason, give this order, she willingly relies on his authority alone.

Said I not unto thee - This was implied in what he had said about the resurrection of her brother, John 11:23-25. There would be a manifestation of the glory of God in raising him up which she would be permitted, with all others, to behold.
The glory of God - The power and goodness displayed in the resurrection. It is probable that Martha did not really expect that Jesus would raise him up, but supposed that he went there merely to see the corpse. Hence, when he directed them to take away the stone, she suggested that by that time the body was offensive.

If thou wouldest believe, etc. - So it appears that it is faith alone that interests the miraculous and saving power of God in behalf of men. Instead of δοξαν, the glory, one MS. reads δυναμιν, the miraculous power.

Jesus saith unto her, said I not unto thee,.... Not in so many words, but what might be concluded from what he said; yea, the following express words might be delivered by Christ, in his conversation with Martha, though they are not before recorded by the evangelist:
that if thou wouldst believe thou shouldest see the glory of God; a glorious work of God, wherein the glory of his power and goodness would be displayed, and the Son of God be glorified, or should see such a miracle wrought, which should engage her to glorify God; and on account of which, she would see just reason to do it, and would be concerned in it: and when it would appear that the sickness and death of her brother, which had given her and her sister so much distress and uneasiness, were for the glory of God, and the honour of Christ; see John 11:4. Moreover, to "see the glory of God", is to see Christ, who is the brightness of his father's glory; and though she had a sight of him now, and before this time, with her bodily eyes, and also with the eyes of her understanding, and knew that he was the Son of God, and the true Messiah; yet it is suggested, that upon a fresh and strong exercise of faith on Christ, with respect to the resurrection of her brother, and by means of that, she should have a clearer view of his glory, as the only begotten of the Father; for as he was declared to be the Son of God, by his own resurrection from the dead afterwards, so he was more fully manifested to be that glorious and divine person, by his raising others from the dead, than by any other miracle; and to be indulged with such a sight of him, is a very high favour; see Psalm 63:2; and such who have their faith most in exercise, see much of the glory of God, both in the face of Christ, and in his providences, and the performance of his promises.

Jesus saith unto her, Said I not unto thee, that if thou wouldest believe, thou shouldest see the glory of God?--He had not said those very words, but this was the scope of all that He had uttered to her about His life-giving power (John 11:23, John 11:25-26); a gentle yet emphatic and most instructive rebuke: "Why doth the restoration of life, even to a decomposing corpse, seem hopeless in the presence of the Resurrection and the Life? Hast thou yet to learn that 'if thou canst believe, all things are possible to him that believeth?'" (Mark 9:23).

Said I not - It appears by this, that Christ had said more to Martha than is before recorded.
