John 3:17

For there are two Advents of Christ, that which has been, and that which is to be; and the two are not for the same purpose; the first came to pass not that He might search into our actions, but that He might remit; the object of the second will be not to remit, but to enquire. Therefore of the first He saith, "I came not to condemn the world, but to save the world"; but of the second, "When the Son shall have come in the glory of His Father, He shall set the sheep on His right hand, and the goats on His left." And they shall go, these into life; and these into eternal punishment. Yet His former coming was for judgment, according to the rule of justice. Why? Because before His coming there was a law of nature, and the prophets, and moreover a written Law, and doctrine, and ten thousand promises, and manifestations of signs, and chastisements, and vengeances, and many other things which might have set men right, and it followed that for all these things He would demand account; but, because He is merciful, He for a while pardons instead of making enquiry. For had He done so, all would at once have been hurried to perdition. For "all," it saith, "have sinned, and come short of the glory of God." Seest thou the unspeakable excess of His lovingkindness?

Yet if He "came not to judge the world," how is "he that believeth not judged already," if the time of "judgment" has not yet arrived? He either means this, that the very fact of disbelieving without repentance is a punishment, (for to be without the light, contains in itself a very severe punishment,) or he announces beforehand what shall be. For as the murderer, though he be not as yet condemned by the decision of the judge, is still condemned by the nature of the thing, so is it with the unbeliever. Since Adam also died on the day that he ate of the tree; for so ran the decree, "In the day that ye eat of the tree, ye shall die"; yet he lived. How then "died" he? By the decree; by the very nature of the thing; for he who has rendered himself liable to punishment, is under its penalty, and if for a while not actually so, yet he is by the sentence.

Lest any one on hearing, "I came not to judge the world," should imagine that he might sin unpunished, and should so become more careless, Christ stops such disregard by saying, "is judged already"; and because the "judgment" was future and not yet at hand, He brings near the dread of vengeance, and describes the punishment as already come. And this is itself a mark of great lovingkindness, that He not only gives His Son, but even delays the time of judgment, that they who have sinned, and they who believe not, may have power to wash away their transgressions.

"For God sent not His Son into the world to judge the world, but that the world through Him may be saved." So far, then, as it lies in the physician, He is come to heal the sick. He that will not observe the orders of the physician destroys himself. He is come a Saviour to the world: why is He called the Saviour of the world, but that He is come to save the world, not to judge the world? Thou wilt not be saved by Him; thou shalt be judged of thyself.

(Tr. xii. c. 12) For why is He called the Saviour of the world, but because Ho saves the world? The physician, so far as his will is concerned, heals the sick. If the sick despises or will not observe the directions of the physician, he destroys himself.
