"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." 1 John 3:10The difference between the children of God and the children of the devil is in their works. The children of God practice righteousness. In other words, they do not live in sin.
As for the children of the devil, they practice unrighteousness. That is, they live in sin.
