14 I did write to you, fathers, because ye have known him who [is] from the beginning; I did write to you, young men, because ye are strong, and the word of God in you doth remain, and ye have overcome the evil.

15 Love not ye the world, nor the things in the world; if any one doth love the world, the love of the Father is not in him,

16 because all that [is] in the world -- the desire of the flesh, and the desire of the eyes, and the ostentation of the life -- is not of the Father, but of the world,

17 and the world doth pass away, and the desire of it, and he who is doing the will of God, he doth remain -- to the age.

18 Little youths, it is the last hour; and even as ye heard that the antichrist doth come, even now antichrists have become many -- whence we know that it is the last hour;
