17 Every wrong thing we do is sin. But there are sins that do not lead to death.
18 We know that those who are children of God do not keep on sinning. The Son of God keeps them safe. The evil one can't harm them.
19 We know that we are children of God. We know that the whole world is under the control of the evil one.
20 We also know that the Son of God has come. He has given us understanding. Now we can know the One who is true. And we belong to the One who is true. We also belong to his Son, Jesus Christ. He is the true God. He is eternal life.
