Children of God Love One Another
4Everyone who practices sin also practices lawlessness; and sin is lawlessness. 5You know that He appeared in order to take away sins; and in Him there is no sin. 6No one who remains in Him sins continually; no one who sins continually has seen Him or knows Him. 7Little children, make sure no one deceives you; the one who practices righteousness is righteous, just as He is righteous; 8the one who practices sin is of the devil; for the devil has been sinning from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil. 9No one who has been born of God practices sin, because His seed remains in him; and he cannot sin continually, because he has been born of God. 10By 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 and sister.
