1 Jean 5:11-13

11καὶ αὕτη ἐστὶν ἡ μαρτυρία, ὅτι ζωὴν αἰώνιον ἔδωκεν ἡμῖν ὁ Θεός, καὶ αὕτη ἡ ζωὴ ἐν τῷ υἱῷ αὐτοῦ ἐστιν.

12ὁ ἔχων τὸν υἱὸν, ἔχει τὴν ζωήν· ὁ μὴ ἔχων τὸν υἱὸν τοῦ Θεοῦ τὴν ζωὴν οὐκ ἔχει.

13Ταῦτα ἔγραψα ὑμῖν, τοῖς πιστεύουσιν εἰς τὸ ὄνομα τοῦ ὑιοῦ τοῦ Θεοῦ, ἵνα εἰδῆτε ὅτι ζωὴν ἔχετε αἰώνιον, καὶ ἵνα πιστεύητε εἰς τὸ ὄνομα τοῦ υἱοῦ τοῦ Θεοῦ.
