1 John 2:15; 1 John 2:24; 1 John 2:28

1 John 2:15

15 Have no love for the world or for the things which are in the world. If any man has love for the world, the love of the Father is not in him.

1 John 2:24

24 But as for you, keep in your hearts the things which were made clear to you from the first. If you keep these things in your hearts you will be kept in the Father and the Son.

1 John 2:28

28 And now, my children, keep your hearts in him; so that at his revelation, we may have no fear or shame before him at his coming.
