18 πιστὸς δὲ ὁ Θεὸς, ὅτι ὁ λόγος ἡμῶν ὁ πρὸς ὑμᾶς οὐκ ἐγένετο ναὶ καὶ οὔ.
19 ὁ γὰρ τοῦ Θεοῦ υἱὸς Ἰησοῦς Χριστὸς ὁ ἐν ὑμῖν δι’ ἡμῶν κηρυχθείς, δι’ ἐμοῦ καὶ Σιλουανοῦ καὶ Τιμοθέου, οὐκ ἐγένετο ναὶ καὶ οὔ, ἀλλὰ ναὶ ἐν αὐτῷ γέγονεν.
20 ὅσαι γὰρ ἐπαγγελίαι Θεοῦ, ἐν αὐτῷ τὸ ναί, καὶ ἐν αὐτῷ τὸ ἀμὴν, τῷ Θεῷ πρὸς δόξαν δι’ ἡμῶν.
21 ὁ δὲ βεβαιῶν ἡμᾶς σὺν ὑμῖν εἰς Χριστὸν, καὶ χρίσας ἡμᾶς, Θεός,
22 ὁ καὶ σφραγισάμενος ἡμᾶς, καὶ δοὺς τὸν ἀρραβῶνα τοῦ Πνεύματος ἐν ταῖς καρδίαις ἡμῶν.
23 Ἐγὼ δὲ μάρτυρα τὸν Θεὸν ἐπικαλοῦμαι ἐπὶ τὴν ἐμὴν ψυχήν, ὅτι φειδόμενος ὑμῶν οὐκέτι ἦλθον εἰς Κόρινθον.
24 οὐχ ὅτι κυριεύομεν ὑμῶν τῆς πίστεως, ἀλλὰ συνεργοί ἐσμεν τῆς χαρᾶς ὑμῶν· τῇ γὰρ πίστει ἑστήκατε.
