1 John 5: 18 We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him.

If we keep ourselves in God, the wicked one does not touch us.

1 John 5:19 We know that we are of God, and the whole world lies under the sway of the wicked one.

We separate ourselves from this world and the grasp of the enemy.

1 John 5:20 And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
