4. ὑμεῖς ἐκ τοῦ Θεοῦ ἐστε, τεκνία, καὶ νενικήκατε αὐτούς· ὅτι μείζων ἐστὶν ὁ ἐν ὑμῖν ἢ ὁ ἐν τῷ κόσμῳ.
5. αὐτοὶ ἐκ τοῦ κόσμου εἰσί· διὰ τοῦτο ἐκ τοῦ κόσμου λαλοῦσι καὶ ὁ κόσμος αὐτῶν ἀκούει.
6. ἡμεῖς ἐκ τοῦ Θεοῦ ἐσμεν· ὁ γινώσκων τὸν Θεὸν, ἀκούει ἡμῶν· ὃς οὐκ ἔστιν ἐκ τοῦ Θεοῦ, οὐκ ἀκούει ἡμῶν. ἐκ τούτου γινώσκομεν τὸ πνεῦμα τῆς ἀληθείας καὶ τὸ πνεῦμα τῆς πλάνης.
7. Ἀγαπητοί, ἀγαπῶμεν ἀλλήλους· ὅτι ἡ ἀγάπη ἐκ τοῦ Θεοῦ ἐστι, καὶ πᾶς ὁ ἀγαπῶν, ἐκ τοῦ Θεοῦ γεγέννηται, καὶ γινώσκει τὸν Θεόν.
8. ὁ μὴ ἀγαπῶν, οὐκ ἔγνω τὸν Θεόν· ὅτι ὁ Θεὸς ἀγάπη ἐστίν.
9. ἐν τούτῳ ἐφανερώθη ἡ ἀγάπη τοῦ Θεοῦ ἐν ἡμῖν, ὅτι τὸν υἱὸν αὐτοῦ τὸν μονογενῆ ἀπέσταλκεν ὁ Θεὸς εἰς τὸν κόσμον, ἵνα ζήσωμεν δι’ αὐτοῦ.
10. ἐν τούτῳ ἐστὶν ἡ ἀγάπη, οὐχ ὅτι ἡμεῖς ἠγαπήσαμεν τὸν Θεόν, ἀλλ’ ὅτι αὐτὸς ἠγάπησεν ἡμᾶς, καὶ ἀπέστειλε τὸν υἱὸν αὐτοῦ ἱλασμὸν περὶ τῶν ἁμαρτιῶν ἡμῶν.
11. ἀγαπητοί, εἰ οὕτως ὁ Θεὸς ἠγάπησεν ἡμᾶς, καὶ ἡμεῖς ὀφείλομεν ἀλλήλους ἀγαπᾶν.
12. Θεὸν οὐδεὶς πώποτε τεθέαται· ἐὰν ἀγαπῶμεν ἀλλήλους, ὁ Θεὸς ἐν ἡμῖν μένει, καὶ ἡ ἀγάπη αὐτοῦ, τετελειωμένη ἐστιν ἐν ἡμῖν.
