4:1 ἀγαπητοί, μὴ παντὶ πνεύματι πιστεύετε, ἀλλὰ δοκιμάζετε τὰ πνεύματα εἰ ἐκ τοῦ θεοῦ ἐστιν, ὅτι πολλοὶ ψευδοπροφῆται ἐξεληλύθασιν εἰς τὸν κόσμον.
4:2 ἐν τούτῳ γινώσκετε τὸ πνεῦμα τοῦ θεοῦ· πᾶν πνεῦμα ὃ ὁμολογεῖ ἰησοῦν χριστὸν ἐν σαρκὶ ἐληλυθότα ἐκ τοῦ θεοῦ ἐστιν,
4:3 καὶ πᾶν πνεῦμα ὃ μὴ ὁμολογεῖ τὸν ἰησοῦν ἐκ τοῦ θεοῦ οὐκ ἔστιν· καὶ τοῦτό ἐστιν τὸ τοῦ ἀντιχρίστου, ὃ ἀκηκόατε ὅτι ἔρχεται, καὶ νῦν ἐν τῶ κόσμῳ ἐστὶν ἤδη.
4:4 ὑμεῖς ἐκ τοῦ θεοῦ ἐστε, τεκνία, καὶ νενικήκατε αὐτούς, ὅτι μείζων ἐστὶν ὁ ἐν ὑμῖν ἢ ὁ ἐν τῶ κόσμῳ.
4:5 αὐτοὶ ἐκ τοῦ κόσμου εἰσίν· διὰ τοῦτο ἐκ τοῦ κόσμου λαλοῦσιν καὶ ὁ κόσμος αὐτῶν ἀκούει.
4:6 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.
4:7 ἀγαπητοί, ἀγαπῶμεν ἀλλήλους, ὅτι ἡ ἀγάπη ἐκ τοῦ θεοῦ ἐστιν, καὶ πᾶς ὁ ἀγαπῶν ἐκ τοῦ θεοῦ γεγέννηται καὶ γινώσκει τὸν θεόν.
4:8 ὁ μὴ ἀγαπῶν οὐκ ἔγνω τὸν θεόν, ὅτι ὁ θεὸς ἀγάπη ἐστίν.
4:9 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.
4:10 ἐν τούτῳ ἐστὶν ἡ ἀγάπη, οὐχ ὅτι ἡμεῖς ἠγαπήκαμεν τὸν θεόν, ἀλλ᾽ ὅτι αὐτὸς ἠγάπησεν ἡμᾶς καὶ ἀπέστειλεν τὸν υἱὸν αὐτοῦ ἱλασμὸν περὶ τῶν ἁμαρτιῶν ἡμῶν.
4:11 ἀγαπητοί, εἰ οὕτως ὁ θεὸς ἠγάπησεν ἡμᾶς, καὶ ἡμεῖς ὀφείλομεν ἀλλήλους ἀγαπᾶν.
4:12 θεὸν οὐδεὶς πώποτε τεθέαται· ἐὰν ἀγαπῶμεν ἀλλήλους, ὁ θεὸς ἐν ἡμῖν μένει καὶ ἡ ἀγάπη αὐτοῦ ἐν ἡμῖν τετελειωμένη ἐστιν.
4:13 ἐν τούτῳ γινώσκομεν ὅτι ἐν αὐτῶ μένομεν καὶ αὐτὸς ἐν ἡμῖν, ὅτι ἐκ τοῦ πνεύματος αὐτοῦ δέδωκεν ἡμῖν.
4:14 καὶ ἡμεῖς τεθεάμεθα καὶ μαρτυροῦμεν ὅτι ὁ πατὴρ ἀπέσταλκεν τὸν υἱὸν σωτῆρα τοῦ κόσμου.
4:15 ὃς ἐὰν ὁμολογήσῃ ὅτι ἰησοῦς ἐστιν ὁ υἱὸς τοῦ θεοῦ, ὁ θεὸς ἐν αὐτῶ μένει καὶ αὐτὸς ἐν τῶ θεῶ.
4:16 καὶ ἡμεῖς ἐγνώκαμεν καὶ πεπιστεύκαμεν τὴν ἀγάπην ἣν ἔχει ὁ θεὸς ἐν ἡμῖν. ὁ θεὸς ἀγάπη ἐστίν, καὶ ὁ μένων ἐν τῇ ἀγάπῃ ἐν τῶ θεῶ μένει καὶ ὁ θεὸς ἐν αὐτῶ μένει.
4:17 ἐν τούτῳ τετελείωται ἡ ἀγάπη μεθ᾽ ἡμῶν, ἵνα παρρησίαν ἔχωμεν ἐν τῇ ἡμέρᾳ τῆς κρίσεως, ὅτι καθὼς ἐκεῖνός ἐστιν καὶ ἡμεῖς ἐσμεν ἐν τῶ κόσμῳ τούτῳ.
4:18 φόβος οὐκ ἔστιν ἐν τῇ ἀγάπῃ, ἀλλ᾽ ἡ τελεία ἀγάπη ἔξω βάλλει τὸν φόβον, ὅτι ὁ φόβος κόλασιν ἔχει, ὁ δὲ φοβούμενος οὐ τετελείωται ἐν τῇ ἀγάπῃ.
4:19 ἡμεῖς ἀγαπῶμεν, ὅτι αὐτὸς πρῶτος ἠγάπησεν ἡμᾶς.
4:20 ἐάν τις εἴπῃ ὅτι ἀγαπῶ τὸν θεόν, καὶ τὸν ἀδελφὸν αὐτοῦ μισῇ, ψεύστης ἐστίν· ὁ γὰρ μὴ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ ὃν ἑώρακεν, τὸν θεὸν ὃν οὐχ ἑώρακεν οὐ δύναται ἀγαπᾶν.
4:21 καὶ ταύτην τὴν ἐντολὴν ἔχομεν ἀπ᾽ αὐτοῦ, ἵνα ὁ ἀγαπῶν τὸν θεὸν ἀγαπᾷ καὶ τὸν ἀδελφὸν αὐτοῦ.
