Assurance and Sin

“No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother” (1 John 3:9–10).

John concludes this section with the summary statement, By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God. There are only two groups of people in the world (cf. Prov. 15:9): the children of God and the children of the devil. The first exhibits God’s righteous character through obeying His law (cf.Luke 1:6); the second exhibits Satan’s sinful character by disregarding the Word and habitually sinning (cf. Pss. 36:3; 119:150; Rom. 2:8). No matter what people may profess, or what past religious ritual or experience they may point to, anyone who does not practice righteousness is not of God, nor the one who does not love his brother. . . .
