1 John 2:15-19

Revised Standard Version Catholic Edition

¹⁵ Do not love the world or the things in the world. If any one loves the world, love for the Father is not in him. ¹⁶ For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world. ¹⁷ And the world passes away, and the lust of it; but he who does the will of God abides for ever.

Warning against Antichrists

¹⁸ Children, it is the last hour;^[a] and as you have heard that antichrist is coming, so now many antichrists have come; therefore we know that it is the last hour. ¹⁹ They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out, that it might be plain that they all are not of us.
