And the other answering. In this wicked man a striking mirror of the unexpected and incredible grace of God is held out to us, not only in his being suddenly changed into a new man, when he was near death, and drawn from hell itself to heaven, but likewise in having obtained in a moment the forgiveness of all the sins in which he had been plunged through his whole life, and in having been thus admitted to heaven before the apostles and first-fruits of the new Church. First, then, a remarkable instance of the grace of God shines in the conversion of that man. For it was not by the natural movement of the flesh that he laid aside his fierce cruelty and proud contempt of God, so as to repent immediately, but he was subdued by the hand of God; as the whole of Scripture shows that repentance is His work. And so much the more excellent is this grace, that it came beyond the expectation of all. For who would ever have thought that a robber, in the very article of death, would become not only a devout worshiper of God, but a distinguished teacher of faith and piety to the whole world, so that we too must receive from his mouth the rule of a true and proper confession? Now the first proof which he gave of his repentance was, that he severely reproved and restrained the wicked forwardness of his companion. He then added a second, by humbling himself in open acknowledgment of his crimes, and ascribing to Christ the praise due to his righteousness. Thirdly, he displayed astonishing faith by committing himself and his salvation to the protection of Christ, while he saw him hanging on the cross and near death. Dost not thou fear God? Though these words are tortured in various ways by commentators, yet the natural meaning of them appears to me to be, What is the meaning of this, that even this condemnation does not compel thee to fear God? For the robber represents it as an additional proof of the hard-heartedness of his companion, that when reduced to the lowest straits, he does not even now begin to fear God. But to remove all ambiguity, it is proper to inform the reader that an impudent and detestable blasphemer, who thought that he might safely indulge in ridicule, is summoned to the judgment-seat of God; for though he had remained all his life unmoved, he ought to have trembled when he saw that the hand of God was armed against him, and that he must soon render an account of all his crimes; It was, therefore, a proof of desperate and diabolical obstinacy, that while God held him bound by the final judgment, he did not even then return to a sound mind; for if there had been the smallest particle of godliness in the heart of that man, he would at least have been constrained to yield to the fear of God. We now perceive the general meaning of his words, that those men, in whom even punishments do not produce amendment, are desperate, and totally destitute of the fear of God. I interpret the words en to auto krimati to mean not in the same condemnation, but during the condemnation itself; [1] as if the robber had said, Since thou art even now in the jaws of death, thou oughtest to be aroused to acknowledge God as thy Judge. Hence, too, we draw a useful doctrine, that those whom punishments do not train to humility do altogether resist God; for they who possess any fear of God must necessarily be overwhelmed with shame, and struck silent.

1 - "Je les pren paur la condamnation presente, et laquelle ne menace point de loin, mais tient desja la personne, et se fait sentir." -- "I take them for the condemnation which is present, and which does not threaten at a distance, but already holds the person, and makes itself be felt."

Dost not thou fear God - You are condemned to die as well as he. It is improper for you to rail on him as the rulers and Romans do. God is just, and you are hastening to his bar, and you should, therefore, fear him, and fear that he will punish you for railing on this innocent man.
Same condemnation - Condemnation to death; not death for the same thing, but the same "kind" of death.

Dost not thou fear God - The sufferings of this person had been sanctified to him, so that his heart was open to receive help from the hand of the Lord: he is a genuine penitent, and gives the fullest proof he can give of it, viz. the acknowledgment of the justice of his sentence. He had sinned, and he acknowledges his sin; his heart believes unto righteousness, and with his tongue he makes confession unto salvation. While he condemns himself he bears testimony that Jesus was innocent. Bishop Pearce supposes that these were not robbers in the common sense of the word, but Jews who took up arms on the principle that the Romans were not to be submitted to, and that their levies of tribute money were oppressive; and therefore they made no scruple to rob all the Romans they met with. These Jews Josephus calls λῃσται, robbers, the same term used by the evangelists. This opinion gains some strength from the penitent thief's confession: We receive the reward of our deeds - we rose up against the government, and committed depredations in the country; but this man hath done nothing amiss - ατοπον, out of place, disorderly, - nothing calculated to raise sedition or insurrection; nor inconsistent with his declarations of peace and good will towards all men, nor with the nature of that spiritual kingdom which he came to establish among men; though he is now crucified under the pretense of disaffection to the Roman government.

But the other answering, rebuked him,.... That is, the other malefactor made answer to him, and reproved him for his baseness and wickedness:
saying, dost not thou fear God; or "neither dost thou fear God", any more than these priests, people, and soldiers, that are acting such a barbarous and inhuman part to a man in misery: and wilt thou do the same, and show that thou art an impious wretch, now thou art just going out of the world, and neither fears God, nor regards man, and art without compassion to a fellow sufferer, adding sin to sin,
seeing thou art in the same condemnation? undergoing the same sort of punishment, though not on the same account, which might be the reason why they suffered on the same day: for the Jews say (a), they never judge (or condemn) two in one day, but one today, and the other tomorrow; but if they are in one transgression,
, "and one death", as an adulterer with an adulteress, they condemn them both in one day; but if the adulterer lies with a priest's daughter, seeing he is to be strangled, and she to be burnt, they do not execute them both in one day.''
(a) Maimon. Hilch. Sanhedrin, c. 14. sect. 10.

Dost not thou--"thou" is emphatic: "Let others jeer, but dost thou?"
fear God--Hast thou no fear of meeting Him so soon as thy righteous Judge? Thou art within an hour or two of eternity, and dost thou spend it in reckless disregard of coming judgment?
in the same condemnation--He has been condemned to die, but is it better with thee? Doth even a common lot kindle no sympathy in thy breast?

The other rebuked him - What a surprising degree was here of repentance, faith, and other graces! And what abundance of good works, in his public confession of his sin, reproof of his fellow criminal, his honourable testimony to Christ, and profession of faith in him, while he was in so disgraceful circumstances as were stumbling even to his disciples! This shows the power of Divine grace. But it encourages none to put off their repentance to the last hour; since, as far as appears, this was the first time this criminal had an opportunity of knowing any thing of Christ, and his conversion was designed to put a peculiar glory on our Saviour in his lowest state, while his enemies derided him, and his own disciples either denied or forsook him.
