Book of 1 John Chapter 2 Vs. 29

 Children of God

1 John 2:29 "If ye know that he is righteous, ye know that every one that doeth righteousness is born of him."

If ye know... Three things' Christians know:

1. That Christ is righteous.

2. That every born-again person is righteous.

3. That doing righteousness is proof of the new birth (1Jhn. 3:6-10; 5:1-4, 5:18).

If ye know - ye know (ἐὰν εἰδῆτε - γινώσκετε)

If ye know absolutely that He is righteous, ye perceive that every one, etc. See on John 2:24. Ye perceive may be taken as imperative: perceive or know ye.

Is born of Him (ἐξ αὐτοῦ γεγέννηται)

The interpreters differ as to the reference of Him; some referring it to God, and others to Christ. Against the latter is the fact that men are not said to be born of Christ, but of God; and that to be born of God is a characteristic phrase of John, while to be born of Christ is a phrase which occurs nowhere. On the other hand, the undoubted reference to Christ in 1Jhn. 2:28, would seem to demand a similar reference here. Men are said to abide in Christ as well as in God, and to be born of the Spirit. Westcott's remark is pertinent. When John thinks of God in relation to men, he never thinks of Him apart from Christ (see 1Jhn. 5:20); and again, he never thinks of Christ in His human nature without adding the thought of His divine nature. Thus a rapid transition is possible from the one aspect of the Lord's divine-human person to the other.

every one that … This is the second feature of the believer’s hope in 2:28-3:3. The hope of Christ’s return not only sustains faith, verse 28, but makes righteousness a habit. The term for born is the same verb used in John 3:7, where Jesus told Nicodemus that he must be born again.

Those truly born again as God’s children have their heavenly Father’s righteous nature (1Pet. 1:3, 13-16). As a result, they will display characteristics of God’s righteousness. John looks from effect righteous behavior to cause being truly born again to affirm that righteous living is the proof of being born again (Jas. 2:20, 26; 2Pet. 3:11).

Righteous (δίκαιος)

Used by John both of God and of Christ. Of God, 1Jhn. 1:9; John 17:25; Rev. 16:5; of Christ, 1Jhn. 2:1; 3:7. Compare Acts 3:14; 7:52; 22:14.

The idea seems to be that he who practices what is right, being born of God (3:9), need not fear Christ’s coming, verse 28. Spiritual rebirth is stressed in John. (See 4:7; 5:1, 4, 18; also John 1:13; 3:3-8).

A Christian is born again of the Spirit. Our flesh is buried in water baptism, and we rise to new life in Him. This is speaking of Jesus Christ the Righteous. We take on His righteousness.

Is born of Him (ἐξ αὐτοῦ γεγέννηται)

Rev., begotten. The first occurrence of the phrase in the Epistle.

Discerning the children of God

At this point John began to develop a line of thought which culminates in the acquisition of the boldness of which he had just spoken (1Jhn. 2:28; cf. 1Jhn. 4:17-19). The fellowship with the apostolic circle and with God which he had in mind (cf. 1Jhn. 1:3) requires discerning the way the lives of God’s children are manifested in their actions. John was moving toward the thought that when one’s life is properly manifested, God Himself is manifested in it (1Jhn. 4:12-16).

This verse introduces for the first time in 1 John the explicit thought of new birth. Since the readers know that He God the Father or God the Son is righteous, they would also know that everyone who does what is right has been born of Him the pronoun here probably refers to God the Father who regenerates. The phrase born of God occurs in 1Jhn. 3:9; 4:7; 5:1, 5:4, 5:18 twice. The statement has nothing to do with the readers’ individual assurance of salvation. It is rather an assertion that when they see real righteousness what is right translates tēn dikaiosynēn exhibited, they can be sure that the person who exhibits it is a child of God. This righteousness, of course, for John can only mean the kind that Christ had enjoined. It has nothing to do with mere humanistic kindness and morality. The converse of John’s statement does not follow, namely, that everyone who is born of God does righteousness. John knew that Christians can walk in the darkness and are susceptible to sin (1Jhn. 1:6, 1:8; 2:1). He was writing here of the way one can see the new birth in the actions of others.
