Why should it be thought ... - The force of this question will be better seen by an exclamation point after why τί ti. "What! is it to be thought a thing incredible?" etc. It intimates surprise that it should be thought incredible, or implies that no reason could be given why such a doctrine should be unworthy of belief.

A thing incredible - A doctrine which cannot be credited or believed. Why should it be regarded as absurd?

With you - This is in the plural number, and it is evident that Paul here addressed, not Agrippa alone, but those who sat with him. There is no evidence that Agrippa doubled that the dead could be raised, but Festus, and those who were with him, probably did, and Paul, in the ardor of his speech, turned and addressed the entire assembly. It is very evident that we have only an outline of this argument, and there is every reason to suppose that Paul would dwell on each part of the subject at greater length than is here recorded.

That God should raise the dead - Why should it be regarded as absurd that God - who has all power, who is the creator of all, who is the author of the human frame should again restore man to life and continue his future existence? The resurrection is no more incredible than the original creation of the body, and it is attended with no greater difficulties. And as the perfections of God will be illustrated by his raising up the dead; as the future state is necessary to the purposes of justice in vindicating the just and punishing the unjust, and as God is a righteous moral governor, it should not be regarded as an absurdity that he will raise up those who have died, and bring them to judgment.

That God should raise the dead? - As Agrippa believed in the true God, and knew that one of his attributes was omnipotence, he could not believe that the resurrection of the dead was an impossible thing; and to this belief of his the apostle appeals; and the more especially, because the Sadducees denied the doctrine of the resurrection, though they professed to believe in the same God. Two attributes of God stood pledged to produce this resurrection: his truth, on which his promise was founded; and his power, by which the thing could be easily affected, as that power is unlimited.

Some of the best critics think this verse should be read thus: What! should it be thought a thing incredible with you, if God should raise the dead?

Why should it be thought a thing incredible with you,.... You Heathens and Sadducees; for the doctrine of the resurrection of the dead was thought an incredible doctrine by the Heathens in general, and therefore was laughed at by the Stoic and Epicurean philosophers at Athens, when preached by the apostle there; and by a particular sect among the Jews, the Sadducees; and the apostle may be thought either to address himself to Festus, the Roman governor, and to the chief captains, who were present, and, being Heathens, disbelieved this doctrine; or else to King Agrippa, who might be a Sadducee, and to such of the Sadducees as were in court, and expostulate with them, why it should be looked upon as a thing by no means to be credited,

that God should raise the dead; which may be understood both of the particular resurrection of Christ from the dead, which was not believed, neither by the Romans nor by the Jews, and neither by Pharisees nor Sadducees; or of the general resurrection of the dead, which was judged from the nature of things to be impracticable, and impossible by the latter, as well as by the Heathens: but since God is omniscient and omnipotent, and just and true, knows where every particle of a dead body lies, and can gather all together, and inspire with life; which he can as easily do, as to form all things out of nothing, as he did; and his justice and veracity seem to require, that the same bodies which have been partners with their souls in sinning, or in sufferings should share with them in woe or in happiness; it can neither be absurd, unreasonable, nor incredible, to suppose that God will raise them from the dead.

That God should raise the dead (εἰ ὁ Θεὸς νεκροὺς ἐγείρει)

Much better, as Rev., if God raises the dead. He does not put it as a supposition, but as a fact: if God raises the dead, as you admit that he has the power to do, and as your own writings tell you that he has done.

{4} Why should it be thought a thing incredible with you, that God should raise the dead?

(4) He proves the resurrection of the dead, first by the power of God, then by the resurrection of Christ, of which he is a sufficient witness.

26:8 Why should it be thought a thing incredible with you? This hope of Israel involved the resurrection of Christ. This Moses and the prophets taught. His countrymen accepted Moses and the prophets, but denied the resurrection as a thing incredible. It was for this hope's sake, of a risen Redeemer, that he was called in question. There was no doubt much said which our record does not preserve, as we have only the outlines of addresses.

26:8 Is it judged by you an incredible thing - It was by Festus, Acts 25:19, to whom Paul answers as if he had heard him discourse.

8. Why should it be thought a thing incredible . that God should raise the dead?-rather, "Why is it judged a thing incredible if God raises the dead?" the case being viewed as an accomplished fact. No one dared to call in question the overwhelming evidence of the resurrection of Jesus, which proclaimed Him to be the Christ, the Son of God; the only way of getting rid of it, therefore, was to pronounce it incredible. But why, asks the apostle, is it so judged? Leaving this pregnant question to find its answer in the breasts of his audience, he now passes to his personal history.

26:1-11 Christianity teaches us to give a reason of the hope that is in us, and also to give honour to whom honour is due, without flattery or fear of man. Agrippa was well versed in the Scriptures of the Old Testament, therefore could the better judge as to the controversy about Jesus being the Messiah. Surely ministers may expect, when they preach the faith of Christ, to be heard patiently. Paul professes that he still kept to all the good in which he was first educated and trained up. See here what his religion was. He was a moralist, a man of virtue, and had not learned the arts of the crafty, covetous Pharisees; he was not chargeable with any open vice and profaneness. He was sound in the faith. He always had a holy regard for the ancient promise made of God unto the fathers, and built his hope upon it. The apostle knew very well that all this would not justify him before God, yet he knew it was for his reputation among the Jews, and an argument that he was not such a man as they represented him to be. Though he counted this but loss, that he might win Christ, yet he mentioned it when it might serve to honour Christ. See here what Paul's religion is; he has not such zeal for the ceremonial law as he had in his youth; the sacrifices and offerings appointed by that, are done away by the great Sacrifice which they typified. Of the ceremonial cleansings he makes no conscience, and thinks the Levitical priesthood is done away in the priesthood of Christ; but, as to the main principles of his religion, he is as zealous as ever. Christ and heaven, are the two great doctrines of the gospel; that God has given to us eternal life, and this life is in his Son. These are the matter of the promise made unto the fathers. The temple service, or continual course of religious duties, day and night, was kept up as the profession of faith in the promise of eternal life, and in expectation of it. The prospect of eternal life should engage us to be diligent and stedfast in all religious exercises. Yet the Sadducees hated Paul for preaching the resurrection; and the other Jews joined them, because he testified that Jesus was risen, and was the promised Redeemer of Israel. Many things are thought to be beyond belief, only because the infinite nature and perfections of Him that has revealed, performed, or promised them, are overlooked. Paul acknowledged, that while he continued a Pharisee, he was a bitter enemy to Christianity. This was his character and manner of life in the beginning of his time; and there was every thing to hinder his being a Christian. Those who have been most strict in their conduct before conversion, will afterwards see abundant reason for humbling themselves, even on account of things which they then thought ought to have been done.
