Confessing Christ in deeds, not only with lips
The preacher has just said Christ saved many by coming and calling us while we were perishing; now he explains how believers should repay that mercy by confessing Christ through obedience and wholehearted honor, not mere lip-service.
Since he has shown us such great mercy, think first of this: we who are alive do not sacrifice to dead gods or worship them. Through him we have come to know the Father of truth. And what is this knowledge of him? It is refusing to deny the one through whom we came to know him.
He himself says, "Whoever confesses me before men, I will confess him before my Father" (Matthew 10:32).
This, then, is our reward, if we confess the one through whom we were saved.
And how do we confess him? By doing what he says and not disobeying his commandments, and by honoring him not only with our lips but from our whole heart and from our whole mind.
For he says also in Isaiah, "This people honors me with their lips, but their heart is far from me" (Isaiah 29:13).
Greek
Τοσοῦτον οὖν ἔλεος ποιήσαντος αὐτοῦ εἰς ἡμᾶς, πρῶτον μέν, ὅτι ἡμεῖς οἱ ζῶντες τοῖς νεκροῖς θεοῖς οὐ θύομεν καὶ οὐ προσκυνοῦμεν αὐτοῖς, ἀλλὰ ἔγνωμεν δἰ αὐτοῦ τὸν πατέρα τῆς ἀληθείας: τίς ἡ γνῶσις ἡ πρὸς αὐτόν, ἢ τὸ μὴ ἀρνεῖσθαι δἰ οὖ ἔγνωμεν αὐτόν;
λέγει δὲ καὶ αὐτός: Τὸν ὁμολογήσαντά με ἐνώπιον τῶν ἀνθρώπων. ὁμολογήσω αὐτὸν ἐνώπιον τοῦ πατρός μου.
οὗτος οὖν ἐστὶν ὁ μισθὸς ἡμῶν, ἐὰν οὖν ὁμολογήσωμεν δἰ οὖ ἐσώθημεν.
ἐν τίνι δὲ αὐτὸν ὁμολογοῦμεν; ἐν τῷ ποιεῖν ἃ λέγει καὶ μὴ παρακούειν αὐτοῦ τῶν ἐντολῶν, καὶ μὴ μόνον χείλεσιν αὐτὸν τιμᾶν, ἀλλὰ ἐξ ὅλης καρδίας καὶ ἐξ ὅλης τῆς διανοίας.
λέγει δὲ καὶ ἐν τῷ Ἡσαΐᾳ: Ὁ λαὸς οὗτος τοῖς χείλεσίν με τιμᾷ, ἡ δὲ καρδία αὐτῶν πόρρω ἄπεστιν ἀπ’ ἐμοῦ.
