1 John 2:12-14; 1 John 2:19

12 I write to you, little children, because the sins have been forgiven you through his name;

13 I write to you, fathers, because ye have known him who [is] from the beginning; I write to you, young men, because ye have overcome the evil. I write to you, little youths, because ye have known the Father:

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.

19 out of us they went forth, but they were not of us, for if they had been of us, they would have remained with us; but -- that they might be manifested that they are not all of us.
