Apostle. God forbid - μη γενοιτο, by no means. God cannot be unjust; were he unjust, he could not be qualified to judge the world, nor inflict that punishment on the unfaithful Jews, to which I refer.
God forbid - Note, Romans 3:4.
For then - If it be admitted that it would be unjust for God to inflict punishment.
How shall God - How will it be right or consistent for him to judge the world.
Judge - To “judge” implies the possibility and the correctness of “condemning” the guilty; for if it were not right to condemn them, judgment would be a farce. This does not mean that God would condemn all the world; but that the fact of judging people implied the possibility and propriety of condemning those who were guilty. It is remarkable that the apostle does not attempt to explain how it could be that God could take occasion from the sins of people to promote his glory; nor does he even admit the fact; but he meets directly the objection. To understand the force of his answer, it must be remembered that it was an admitted fact, a fact which no one among the Jews would call in question, that God would judge the world. This fact was fully taught in their own writings, Genesis 18:25; Ecclesiastes 12:14; Ecclesiastes 11:9. It was besides an admitted point with them that God would condemn the pagan I world; and perhaps the term “world” here refers particularly to them.
But how could this be if it were not right for God to inflict punishment at all? The inference of the objector, therefore, could not be true; though the apostle does not tell us how it was consistent to inflict punishment for offences from which God took occasion to promote his glory. It may be remarked, however, that God will judge offences, not from what he may do in overruling them, but from the nature of the crime itself. The question is not, what good God may bring out of it, but what does the crime itself deserve? what is the character of the offender? what was his intention? It is not what God may do to overrule the offence when it is committed. The just punishment of the murderer is to be determined by the Law, and by his own desert; and not from any reputation for integrity and uprightness which the judge may manifest on his trial; or from any honor which may accrue to the police for detecting him; or any security which may result to the commonwealth from his execution; or from any honor which the Law may gain as a just law by his condemnation. Nor should any of these facts and advantages which may result from his execution, be pleaded in bar of his condemnation. So it is with the sinner under the divine administration. It is indeed a truth Psalm 76:10 that the wrath of man shall praise God, and that he will take occasion from people‘s wickedness to glorify himself as a just judge and moral governor; but this will be no ground of acquittal for the sinner.
