1John 2:12-14

(12)I write to you, little children, Because your sins are forgiven you for His name's sake.  (13)I write to you, fathers, Because you have known Him who is from the beginning. I write to you, young men, Because you have overcome the wicked one. I write to you, little children, Because you have known the Father. (14)I have written to you, fathers, Because you have known Him who is from the beginning. I have written to you, young men, Because you are strong, and the word of God abides in you, And you have overcome the wicked one.

(12)  "Little Children" = teknion = term used by teachers to address their disciples (e.g. Jn 13:13, Gal.4:19, 1Jn 2:1)
       "Forgiven" = aphiemi = apart+to = perfect tense, completed in the past, once and for all, not needing to be repeated.

(13)"from the beginning" = arche = Origen, beginning, first in a series.
