18 We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him. 19 We know that we are of God, and the whole world lies under the sway of the wicked one. 20 And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life. 21 Little children, keep yourselves from idols. Amen. (1 John 5:18–21, NKJV)
God assures Christians of knowing we have eternal life in the Son of God (1 Jno. 5:11-13). We are confident of this wonderful blessing in Christ because we are born of God through His word (Jno. 1:12-13; 3:3, 5; 1 Pet. 1:23). John tells us some things we know as God’s children, which testify to God’s grace and our faith as His children. 1) We know whoever is born of God does not practice sin, but guards himself against the evil one (5:18). We do not say we “have no sin,” but that we practice righteousness (1 Jno. 1:8; 2:29; 3:6-10). 2) We know we are different from the world (5:19). We do not love the world and its lusts, but God and His will (1 Jno. 2:15-17). 3) We know the Son of God has given us an understanding (5:20). Jesus Christ is the Truth, and His word lights our path (Jno. 14:6; 1 Jno. 1:6-7). We have fellowship with the Father and the Son when we walk in (obey) apostolic truth (1 Jno. 1:2-3; 2:3-6; 3:24). Let us guard ourselves against false gods and their false concepts of salvation by faithfully following Jesus Christ (1 Jno. 5:21).
6 who “will render to each one according to his deeds”: 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; (Romans 2:6–7, NKJV)
God’s judgments are just. The Old Testament law and prophets relied on this basic truth when they said, “The soul who sins shall die. The son shall not bear the guilt of the father, nor the father bear the guilt of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself” (Ezekiel 18:20; see Deuteronomy 24:16). Despite this, many still believe men and women are born sinners (born with a sin nature), inheriting the guilt and depravity of Adam’s sin. Yet, today’s passage assures eternal life to those who continue doing what is good because they are seeking “glory, honor, and immortality.” What is the good we must patiently continue to do to receive eternal life? The apostle John said it is practicing righteousness: “My little children, let no one deceive you. He who practices righteousness is righteous, just as He is righteous” (1 John 3:7). The “doing good” that will be rewarded with eternal life is faithful obedience to God (Ephesians 2:10). Today’s question is this: Are you seeking heaven? If so, do you have faith that God will render to you according to your deeds? If so, then do the will of God and be blessed with eternal life. God will keep His word and deliver you a just judgment according to your deeds.
10 In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother. 11 For this is the message that you heard from the beginning, that we should love one another… (1 John 3:10–11, NKJV)
There are obvious differences between the children of God, and the children of the devil. This passage expresses those differences negatively. The person who does not practice righteousness, and the one who does not love his brother, is “not of God.” This is entirely consistent with the apostle’s declaration in Acts 10:35, that “whoever fears Him and works righteousness is accepted by Him.” Practicing righteousness is equivalent to practicing truth, and walking in the light (1 John 1:6-7). Christians live their profession of faith by walking in truth, otherwise, they are “not of God,” and are without God’s approval. For you see, it is sin not to practice righteousness (1 John 3:7-8; James 4:17). As we practice righteousness, we must love our brethren, even as Jesus commanded from the beginning (1 John 13:34-35). The devil’s children do not practice righteousness or brotherly love. To them, these are unnecessary for God’s acceptance. It is a great deception to say how one lives as a Christian does not impact one’s divine approval now, and eternally. May we practice righteousness, and love our brethren. By this, we know we are of God.
