17 All wrongdoing is sin, but there is sin that is not deadly.
18 We know that no one begotten by God sins; but the one begotten by God he protects, and the evil one cannot touch him.
19 We know that we belong to God, and the whole world is under the power of the evil one.
20 We also know that the Son of God has come and has given us discernment to know the one who is true. And we are in the one who is true, in his Son Jesus Christ. He is the true God and eternal life.
21 Children, be on your guard against idols.
