γράφω ὑμῖν τεκνία ὅτι ἀφέωνται ὑμῖν αἱ ἁμαρτίαι διὰ τὸ ὄνομα αὐτοῦ
γράφω ὑμῖν πατέρες ὅτι ἐγνώκατε τὸν ἀπ’ ἀρχῆς
γράφω ὑμῖν νεανίσκοι ὅτι νενικήκατε τὸν πονηρόν  
ἔγραψα ὑμῖν παιδία ὅτι ἐγνώκατε τὸν πατέρα
ἔγραψα ὑμῖν πατέρες ὅτι ἐγνώκατε τὸν ἀπ’ ἀρχῆς
ἔγραψα ὑμῖν νεανίσκοι ὅτι ἰσχυροί ἐστε καὶ ὁ λόγος τοῦ θεοῦ ἐν ὑμῖν μένει καὶ νενικήκατε τὸν πονηρόν

First and foremost, I write to you “babies” newly born into this kind of life.  You’ve been released from your past mistakes - and it’s all thanks to Jesus. I didn’t forget you “fathers,” either.  You knew the “word” long before he walked into our lives.  And you “adolescents” aren’t children anymore!  Even in your inexperience, you’ve conquered the evil force in your lives.  
Remember when I wrote before?  You children knew your Father intimately, like a good child should! As for you “fathers,” you’re just as keen to the “word” as you’ve always been.  And you “adolescents” aren’t children anymore!  You’ve grown strong.  You’ve subdued the temptations of the evil one.  The “word” isn’t going anywhere because it’s safe within you.
