1 Jean 3:10-13

10ἐν τούτῳ φανερά ἐστιν τὰ τέκνα τοῦ θεοῦ καὶ τὰ τέκνα τοῦ διαβόλου. πᾶς ὁ μὴ ποιῶν δικαιοσύνην οὐκ ἔστιν ἐκ τοῦ θεοῦ, καὶ ὁ μὴ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ·

11ὅτι αὕτη ἐστὶν ἡ ἀγγελία ἣν ἠκούσατε ἀπ᾽ ἀρχῆς ἵνα ἀγαπῶμεν ἀλλήλους·

12οὐ καθὼς Κάϊν ἐκ τοῦ πονηροῦ ἦν καὶ ἔσφαξεν τὸν ἀδελφὸν αὐτοῦ· καὶ χάριν τίνος ἔσφαξεν αὐτόν; ὅτι τὰ ἔργα αὐτοῦ πονηρὰ ἦν, τὰ δὲ τοῦ ἀδελφοῦ αὐτοῦ δίκαια.¶

13Καὶ μὴ θαυμάζετε, ἀδελφοί εἰ μισεῖ ὑμᾶς ὁ κόσμος.
