Romans 2:16

16.In which God shall judge the secrets of men (75) Most suitable to the present occasion is this periphrastic definition of judgment: it teaches those, who willfully hide themselves in the recesses of insensibility, that the most secret thoughts and those now completely hid in the depths of their hearts, shall then be brought forth to the light. So he speaks in another place; in order to show to the Corinthians what little value belongs to human judgment, which regards only the outward action, he bids them to wait until the Lord came, who would bring to light the hidden things of darkness, and reveal the secrets of the heart. (1 Corinthians 4:5) When we hear this, let it come to our minds, that we are warned that if we wish to be really approved by our Judge, we must strive for sincerity of heart.

He adds, according to my gospel, intimating, that he announced a doctrine, to which the judgments of men, naturally implanted in them, gave a response: and he calls it his gospel, on account of the ministry; for the authority for setting forth the gospel resides in the true God alone; and it was only the dispensing of it that was committed to the Apostles. It is indeed no matter of surprise, that the gospel is in part called the messenger and the announcer of future judgment: for if the fulfillment and completion of what it promises be deferred to the full revelation of the heavenly kingdom, it must necessarily be connected with the last judgment: and further, Christ cannot be preached without being a resurrection to some, and a destruction to others; and both these things have a reference to the day of judgment. The words, through Jesus Christ, I apply to the day of judgment, though they are regarded otherwise by some; and the meaning is, — that the Lord will execute judgment by Christ, for he is appointed by the Father to be the Judge of the living and of the dead, — which the Apostles always mention among the main articles of the gospel. Thus the sentence will be full and complete, which would otherwise be defective.
