But we are sure - Greek, "We know." That is, it is the common and admitted sentiment of mankind. It is known and believed by people generally that God will punish such crimes. It is implied in this declaration that this was known to the Jews, and it was particularly to the purpose of the apostle so to express himself as to include the Jews. They knew it because it was everywhere taught in the Old Testament, and it was the acknowledged doctrine of the nation. The design of the apostle here, says Calvin, is to take away the subterfuges of the hypocrite, lest he should pride himself if he obtained the praise of human beings, for a far more important trial awaited him at the bar of God. Outwardly he might appear well to people; but God searched the heart, and saw the secret as well as the open deeds of people, and they who practiced secretly what they condemned openly, could not expect to escape the righteous judgment of God. God, without respect of persons would punish wickedness, whether it was open, as among the Gentiles, or whether it was concealed under the guise of great regard for religion, as among the Jews.

The judgment of God - That God condemns it, and will punish it. He regards those who do these things as guilty, and will treat them accordingly.

According to truth - This expression is capable of two meanings. The Hebrews sometimes use it to denote truly or certainly. God will certainly judge and punish such deeds. Another meaning, which is probably the correct one here, is that God will judge those who are guilty of such things, not according to appearance, but in integrity, and with righteousness. He will judge people according to the real nature of their conduct, and not as their conduct may appear to people. The secret, as well as the open sinner therefore; the hypocrite, as well as the abandoned profligate, must expect to be judged according to their true character. This meaning comports with the design of the apostle, which is to show that the Jew, who secretly and hypocritically did the very things which he condemned in the Gentile, could not escape the righteous judgment of God.

Against him - That is, against every man, no matter of what age or nation.

Which commit such things - The crimes enumerated in Romans 1. The apostle is not to be understood as affirming that each and every individual among the Jews was guilty of the specific crimes charged on the pagan, but that they were as a people inclined to the same things. Even where they might be externally moral, they might be guilty of cherishing evil desires in their hearts, and thus be guilty of the offence, Matthew 5:28. When people desire to do evil, and are prevented by the providence of God, it is right to punish them for their evil intentions. The fact that God, prevents them from carrying their evil purposes into execution, does not constitute a difference between their real character and the character of those who are suffered to act out their wicked designs.

Tendencies of Religious Thought in England, 1688-1750.
THE thirty years of peace which succeeded the Peace of Utrecht (1714), was the most prosperous season that England had ever experienced; and the progression, though slow, being uniform, the reign of George II. might not disadvantageously be compared for the real happiness of the community with that more brilliant, but uncertain and oscillatory condition which has ensued. A labourer's wages have never for many ages commanded so large a portion of subsistence as in this part of the 18th century.' (Hallam, …
