παιδία ἐσχάτη ὥρα ἐστίν καὶ καθὼς ἠκούσατε ὅτι ἀντίχριστος ἔρχεται καὶ νῦν ἀντίχριστοι πολλοὶ γεγόνασιν ὅθεν γινώσκομεν ὅτι ἐσχάτη ὥρα ἐστίν   ἐξ ἡμῶν ἐξῆλθαν ἀλλ’ οὐκ ἦσαν ἐξ ἡμῶν εἰ γὰρ ἐξ ἡμῶν ἦσαν μεμενήκεισαν ἂν μεθ’ ἡμῶν ἀλλ’ ἵνα φανερωθῶσιν ὅτι οὐκ εἰσὶν πάντες ἐξ ἡμῶν   καὶ ὑμεῖς χρῖσμα ἔχετε ἀπὸ τοῦ ἁγίου καὶ οἴδατε πάντες

You newcomers have heard the rumors: when this “imposter-anointed” shows his face, time will be short.  What you didn’t know is that these imitators are abounding already.  Time is running out!  They came from among us, but were never really with us.  If they were authentic, they’d still be by our side.  It’s the test of time - it all gets revealed.  But you - you have the real thing and you know it!  You been anointed by the Holy original!
