is a liar, and the truth is not in him.
"A murderer from the beginning, . . . a liar and the father of lies," Satan is "the deceiver of the whole world." Through him sin and death entered the world and by his definitive defeat all creation will be "freed from the corruption of sin and death." Now "we know that anyone born of God does not sin, but He who was born of God keeps him, and the evil one does not touch him. We know that we are of God, and the whole world is in the power of the evil one."
