And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.

People's New Testament

16:31 Neither will they be persuaded, etc. This was demonstrated in the case of Jesus himself. The Jews refused to accept Christ, though Moses and the prophets testified of him. They asked for a sign, and the sign of the prophet Jonah (Mt 12:39 16:4; Lu 11:29,30), his resurrection from the dead, was given. Still they refused to repent. Unbelief is due, not to a lack of evidence, but to a rebellious heart. The seat of skepticism is in the moral nature.

Wesley's Notes

16:31 Neither will they be persuaded - Truly to repent: for this implies an entire change of heart: but a thousand apparitions cannot, effect this. God only can, applying his word.

Matthew Henry's Concise Commentary

16:19-31 Here the spiritual things are represented, in a description of the different state of good and bad, in this world and in the other. We are not told that the rich man got his estate by fraud, or oppression; but Christ shows, that a man may have a great deal of the wealth, pomp, and pleasure of this world, yet perish for ever under God's wrath and curse. The sin of this rich man was his providing for himself only. Here is a godly man, and one that will hereafter be happy for ever, in the depth of adversity and distress. It is often the lot of some of the dearest of God's saints and servants to be greatly afflicted in this world. We are not told that the rich man did him any harm, but we do not find that he had any care for him. Here is the different condition of this godly poor man, and this wicked rich man, at and after death. The rich man in hell lifted up his eyes, being in torment. It is not probable that there are discourses between glorified saints and damned sinners, but this dialogue shows the hopeless misery and fruitless desires, to which condemned spirits are brought. There is a day coming, when those who now hate and despise the people of God, would gladly receive kindness from them. But the damned in hell shall not have the least abatement of their torment. Sinners are now called upon to remember; but they do not, they will not, they find ways to avoid it. As wicked people have good things only in this life, and at death are for ever separated from all good, so godly people have evil things only in this life, and at death they are for ever put from them. In this world, blessed be God, there is no gulf between a state of nature and grace, we may pass from sin to God; but if we die in our sins, there is no coming out. The rich man had five brethren, and would have them stopped in their sinful course; their coming to that place of torment, would make his misery the worse, who had helped to show them the way thither. How many would now desire to recall or to undo what they have written or done! Those who would make the rich man's praying to Abraham justify praying to saints departed, go far to seek for proofs, when the mistake of a damned sinner is all they can find for an example. And surely there is no encouragement to follow the example, when all his prayers were made in vain. A messenger from the dead could say no more than what is said in the Scriptures. The same strength of corruption that breaks through the convictions of the written word, would triumph over a witness from the dead. Let us seek to the law and to the testimony, Isa 8:19,20, for that is the sure word of prophecy, upon which we may rest, 2Pe 1:19. Circumstances in every age show that no terrors, or arguments, can give true repentance without the special grace of God renewing the sinner's heart.
