1 John 4:3-5

New Revised Standard Version Catholic Edition

³ and every spirit that does not confess Jesus^[a] is not from God. And this is the spirit of the antichrist, of which you have heard that it is coming; and now it is already in the world. ⁴ Little children, you are from God, and have conquered them; for the one who is in you is greater than the one who is in the world. ⁵ They are from the world; therefore what they say is from the world, and the world listens to them.
