1 John 3:10

3:3-10 The sons of God know that their Lord is of purer eyes than to allow any thing unholy and impure to dwell with him. It is the hope of hypocrites, not of the sons of God, that makes allowance for gratifying impure desires and lusts. May we be followers of him as his dear children, thus show our sense of his unspeakable mercy, and express that obedient, grateful, humble mind which becomes us. Sin is the rejecting the Divine law. In him, that is, in Christ, was no sin. All the sinless weaknesses that were consequences of the fall, he took; that is, all those infirmities of mind or body which subject man to suffering, and expose him to temptation. But our moral infirmities, our proneness to sin, he had not. He that abides in Christ, continues not in the practice of sin. Renouncing sin is the great proof of spiritual union with, continuance in, and saving knowledge of the Lord Christ. Beware of self-deceit. He that doeth righteousness is righteous, and to be a follower of Christ, shows an interest by faith in his obedience and sufferings. But a man cannot act like the devil, and at the same time be a disciple of Christ Jesus. Let us not serve or indulge what the Son of God came to destroy. To be born of God is to be inwardly renewed by the power of the Spirit of God. Renewing grace is an abiding principle. Religion is not an art, a matter of dexterity and skill, but a new nature.

And the regenerate person cannot sin as he did before he was born of God, and as others do who are not born again. There is that light in his mind, which shows him the evil and malignity of sin. There is that bias upon his heart, which disposes him to loathe and hate sin. There is the spiritual principle that opposes sinful acts. And there is repentance for sin, if committed. It goes against him to sin with forethought. The children of God and the children of the devil have their distinct characters. The seed of the serpent are known by neglect of religion, and by their hating real Christians. He only is righteous before God, as a justified believer, who is taught and disposed to righteousness by the Holy Spirit. In this the children of God are manifest, and the children of the devil. May all professors of the gospel lay these truths to heart, and try themselves by them.

{9} In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, {10} neither he that loveth not his brother. (9) The conclusion: by a wicked life they are known who are governed by the Sprit of the devil: and by a pure life who are God's children. (10) He begins to commend charity towards the brethren as another mark of the sons of God.

Upon what was said, he reduces all men each to their own family and father, concluding it manifest whither they belonged; i.e. he shows, upon the grounds before expressed, who do not belong to God and his family, leaving it thence to be collected, since two fathers and families divide the world, to which they must be reckoned; i.e. they belong not to God, and consequently to that worst of fathers, who first, in the general, do not righteousness; the devil being the first sinner, they are his descendants; and who next, particularly, love not their brethren, which most expressly demonstrates a diabolical nature.

In this (ἐν τούτῳ) See on 1 John 2:3. Children of the devil (τέκνα τοῦ διαβόλου) The only occurrence of the phrase. Compare Acts 13:10, and see John 8:44. Righteousness Here the article is wanting, compare 1 John 3:7. Righteousness is regarded, not in its completeness, but as bearing a particular character. It will be interesting to follow out the same distinction between the following words with and without the article: ἀμαρτία sin; ἀγάπη love; ζωή life; ἀλήθεια truth.

Verse 10. - The question whether "in this" ἐν τούτῳ refers to what precedes or to what follows is here unimportant, for both are similar in meaning; and "in this" may refer to both. "By their fruits ye shall know them." The children of God do righteousness, and not sin; the children of the devil do sin, and not righteousness. Of course, moral parentage is meant in both cases. Nothing here lends any countenance to the view that the writer is a dualist and inculcates two principles of existence - God and the devil. All, whether good or bad, are God's creatures ( John 1:3 ); but while all are his children by creation, some become his children spiritually also, while others become the children of Satan. St. John's "teaching about the devil is not at all agreeable to those who dwell exclusively on the sunny aspects of the world and of life, and would shut their eyes to what is dark and terrible. They like to hear of a Being who is all-gracious and loving; the vision of one who is the enemy of all that is gracious and loving shocks them - they wish to suppose that it belongs to the world's infancy, and that it disappears as we know more" (Maurice). The expression, "the children of the devil," must not be confounded with the Hebraistic expressions, "children of perdition, children of darkness," "children of light, son of death," "son of perdition," etc. As so often, St. John not only restates the case in a new form, but adds a new thought to it - he that loveth not his brother.

This forms the link with the next section (verses 13-24), on brotherly love. Of all failures in doing righteousness this is the most conspicuous - failing to love one's brother. And who is my brother? The answer is the same as to the question, "And who is my neighbour?" Mankind at large. The meaning cannot be limited to the children of God. Even τοὺς ἀδελφούς (verses 14, 16) does not exclude unbelievers, still less does τὸν ἀδελφὸν αὐτοῦ . This is confirmed: (1) By the fact that the opposite case (verse 13) is the children of the world hating Christians ; the true opposite of Christians loving Christians would be the children of the world hating one another. (2) By the cited example of Christ (verse 16), who died for us when we were aliens from God. Of course, if the Christian must love all men, a fortiori he must love Christians. 1 John 3:10

10. children of the devil—(See on [2643]1Jo 3:8; Ac 13:10). There is no middle class between the children of God and the children of the devil. doeth not righteousness—Contrast 1Jo 2:29. he that loveth not his brother—(1Jo 4:8); a particular instance of that love which is the sum and fulfilment of all righteousness, and the token (not loud professions, or even seemingly good works) that distinguishes God's children from the devil's.

In this the children of God are manifest ... - That is, this furnishes a test of their true character. The test is found in doing righteousness, and in the love of the brethren. The former he had illustrated; the latter he now proceeds to illustrate. The general idea is, that if a person is not truly a righteous person, and does not love the brethren, he cannot be a child of God. Perhaps by the phrase in this, using a pronoun in the singular number, he means to intimate that an important part of righteousness consists in brotherly love. Whosoever doeth not righteousness, is not of God - In 1 John 3:7, he had said that "he that doeth righteousness is of God." If that is true, then what he here affirms must be true also, that a man who does not righteousness is not of God. The general idea is the same, that no one can be a true Christian who is not in fact a righteous man. Neither he that loveth not his brother - The illustration of this point continues to 1 John 3:18. The general sense is, that brotherly love is essential to the Christian character, and that he who does not possess it cannot be a Christian. On the nature and importance of brotherly love as an evidence of piety, see the notes at John 13:34-35.

10 . In this ] These words, like ‘for this cause’ ( 1 John 3:1 ) refer to what precedes rather than to what follows: but here what follows is similar to what precedes, so that in any case ‘in this’ means ‘by doing or not doing righteousness’. are manifest ] A man’s principles are invisible, but their results are visible: ‘By their fruits ye shall know them’ ( Matthew 7:16-20 ). the children of the devil ] The expression occurs nowhere else in N. T., but we have ‘son of the devil,’ Acts 13:10 : comp. ‘children of wrath’ ( Ephesians 2:3 ), and ‘ye are of your father the devil’ ( John 8:44 ). All mankind are God’s children by creation: as regards this a creature can have no choice. But a creature endowed with free will can choose his own parent in the moral world. The Father offers him the ‘right to become a child of God’ ( John 1:12 ); but he can refuse this and become a child of the devil instead. There is no third alternative. It was for pressing the doctrine that a tree is known by its fruits to an extreme, and maintaining that a world in which evil exists cannot be the work of a good God, that the heretic Marcion was rebuked by S. John’s disciple Polycarp, in words which read like an adaptation of this text, “I know thee for the firstborn of Satan ” (Iren. Haer. III. iii. 4). And in his Epistle (VII. 1) Polycarp writes, “Whosoever does not confess the witness of the cross is of the devil ”. neither he that loveth not his brother ] Here again note the way in which S.
