1 John 2:15-17, 22-23

Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh and the lust of the eyes and the vainglory of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.

Who is the liar but he that denieth that Jesus is the Christ? This is the antichrist, even he that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father: he that confesseth the Son hath the Father also.
