(4, 5) The best antidote for such false estimates of self is severe self-criticism. Let a man judge his own work, not by comparison with others, but by the ideal standard, then he will see what it is worth and how much he has to boast of. His boasting will be at least real, and not based upon any delusive comparisons. He must stand or fall by himself. He must bear the weight of his own virtues and his own sins. By them he will be judged, and not by any fancied superiority or inferiority to others. For the thought, compare 2Corinthians 10:12-14.

(4) Prove.--Test, or examine, by reference to an objective standard. The word is used specially of the assaying of metals.

Rejoicing in himself alone, and not in another.--Rather, he shall have his ground of boasting with reference to himself alone, and not with reference to his neighbour. He will judge his own actions by the standard properly applicable to them, and will find as much ground for boasting as this will give him, and no more. His standard will be absolute and not relative, and the amount of his boasting will be proportioned accordingly. He will not seek to excuse himself by dwelling upon his neighbour's weaknesses.

Verse 4. - But let every man prove his own work (τὸ δὲ ἔργον ἑαυτοπῦ δοκιμαζέτω ἕκαστος); but his own work let each man bringing to the proof. "His own work;" his own actual conduct. Both "work" and "his own" are weighted with emphasis; "work," as practical behaviour contrasted with professions or self-illusions (comp. 1 Peter 1:17, "Who without respect of persons judgeth according to each man's work"); "his own," as contrasted with these others with whom one is comparing himself to find matter for self-commendation. "Be bringing to the proof;" that is, testing his actual life by the touchstone of God's law, especially of "Christ's law," with the honest purpose of bringing it into accordance therewith. In other words, "Let each man be endeavouring in a spirit of self-watch-fulness to walk orderly according to the Spirit." This notion of practical self-improving attaches to the verb δοκιμάζω ("prove" or" examine") also in Romans 12:2; 1 Corinthians 11:28; Ephesians 3:10. And then shall he have rejoicing in himself alone (καὶ τότε εἰς ἑαυτὸν μόνον τὸ καύχημα ἕξει); and then in regard to himself alone shall he have whereof to glory. The preposition εἰς is used as in Matthew 14:31, Αἰς τί ἐδίστασας; "What didst thou look at that thou didst doubt?" Acts 2:25, "concerning him;" Ephesians 5:32; Romans 4:20; Romans 13:14; Romans 16:19. It depends upon the whole phrase, "shall have his ground of glorying," and not upon the word rendered "ground of glorying" alone. The distinction which ordinarily obtains between verbals of the form of πρᾶγμα and those of the form of πρᾶξις appears to hold good also in respect to καύχημα and καύχησις. Compare the use of καύχησις in 2 Corinthians 7:4 and James 4:16, with that of καύχημα in Romans 4:2, ἔχει καύχημα, "hath whereof to glory;" 1 Corinthians 9:16, οὐκ ἔστι μοι καύχημα, "I have nothing to glory of." In 1 Corinthians 5:6, οὐ καλὸν τὸ καύχημα ὑμῶν, the substantive seems to mean "boast," that is, what is said in boasting, as distinguished from καύχησις, the action of uttering a beast. The verb καυχῶμαι, with its derivatives - a favourite term with St. Paul - often appears to mean "rejoicing" rather than" boasting" (cf. Romans 5:2; Hebrews 3:6); but it seems desirable as a rule to render it by "glorying," with the understanding that the writer has frequently the joyous state of feeling more prominently in his view than the utterance of self-gratulation. What the apostle meant by "having one's ground of glorying in regard to one's own self alone," is well illustrated by what he says respecting himself in 2 Corinthians 1:12, "Our glorying is this, the testimony of our conscience, that in holiness and sincerity of God, not in fleshly wisdom, but in the grace of God, we behaved ourselves in the world, and more abundantly to you-ward." he had been himself in the habit of testing his conduct and spirit by the standard of Christ's law; and this was the fruit. And not in another (καὶ οὐκ εἰς τὸν ἕτερον); and not in regard to that neighbour of his. The article probably points to that neighbour with whom he has been comparing himself; and so, perhaps, also in Romans 2:1. But it may be simply "his neighbour;" "the man who is other than himself;" as it is in 1 Corinthians 6:1 and 1 Cor 10:24, in neither of which passages has any particular "other person" been before referred to.

6:1-5 We are to bear one another's burdens. So we shall fulfil the law of Christ. This obliges to mutual forbearance and compassion towards each other, agreeably to his example. It becomes us to bear one another's burdens, as fellow-travellers. It is very common for a man to look upon himself as wiser and better than other men, and as fit to dictate to them. Such a one deceives himself; by pretending to what he has not, he puts a cheat upon himself, and sooner or later will find the sad effects. This will never gain esteem, either with God or men. Every one is advised to prove his own work. The better we know our own hearts and ways, the less shall we despise others, and the more be disposed to help them under infirmities and afflictions. How light soever men's sins seem to them when committed, yet they will be found a heavy burden, when they come to reckon with God about them. No man can pay a ransom for his brother; and sin is a burden to the soul. It is a spiritual burden; and the less a man feels it to be such, the more cause has he to suspect himself. Most men are dead in their sins, and therefore have no sight or sense of the spiritual burden of sin. Feeling the weight and burden of our sins, we must seek to be eased thereof by the Saviour, and be warned against every sin.But let every man prove his own work,.... Not concern himself about the actions and works of others; let him review his own heart and actions; let him examine, try, and prove his whole conduct in life by the rule of God's word, when he will find enough at home, without bearing hard upon, and censuring others:

and then shall he have rejoicing in himself alone, and not in another; which is either ironically said, he will then see what reason he has to rejoice and glory in his own works, and vaunt over others, and to boast of his performances, and despise others; so far from it, that he will have reason to be ashamed of himself, and to own and acknowledge his unworthiness and unprofitableness: or if, upon such a review, examination, and probation of his works, it shall appear that he has had his conversation in the world, by the grace of God, in simplicity and godly sincerity, this testimony of his conscience will be his rejoicing; see 2 Corinthians 1:12. He may rejoice "in himself", in his own works, as the fruits of grace, but not as the effects of his own power and strength; and may glory and boast of them before men, in vindication of his cause and character, and as evidences of the truth of grace, but not before God, as if they were the matter of his justification and acceptance:

and not in another; that is fallen into sin; making use of his sins and faults to set off himself, and to increase his own praise and condemnation; rejoicing in this, that he is better than others, and is not, as the Pharisee said, as other men are, as wicked as they, or has not fallen into such sins as others have done. He will have occasion to take such a method as this, if his conversation will bear the test; he will have rejoicing in the testimony of his own conscience, and will have no need to compare himself with others; his glorying will be on account of his own actions, and not through a comparison of other men's. This no ways contradicts a man's glorying in God, and rejoicing in Christ Jesus alone, in the business of salvation. It only regards a man's glorying before men, in a modest and humble manner, of what he is enabled to do, by the grace of God, without fetching in the characters of other men that are wicked, or have fallen, to illustrate his own.
