18 We know that everyone who has been born of God does not keep on sinning, but he who was born of God protects him, and the evil one does not touch him.
19 We know that we are from God, and the whole world lies in the power of the evil one.
20 And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life. 21 Little children, keep yourselves from idols.
