Prayer and Thanksgiving

Εύλογητὸς ὁ Θεὸς, ὅτι εἰσήκουσε τῆς φωνῆς τῆς δεήσεώς μου. Κύριος βοηθός μου καὶ ὑπερασπιστής μου· ἐπ' αὐτῷ ἤλπισεν ἡ καρδία μοι καὶ ἐβοηθήθην. Καὶ ἀνέθαλεν ἡ σάρξ μου, καὶ ἐκ θελήματος μου ἐξομολογήσομαι αύτῷ.   Ὁ ἀψευδὴς Θεὸς, πιστούμενος ἑαυτοῦ τὰς ὑποσχέσεις, δι' ὦν ἐπήγγελται λέγων· Ἔτι λαλοῦντός σου ἐρῶ· Ἰδοὺ πὰρειμι· ὡς ἐγγυς ἐστὼς τῶν καθαρῶς αὐτὸν ἐπικαλουμένων, καὶ ὡς οὐ πόῥῥω τυγχάνων τοῦ τὰ πραχθέντα δεηθέντος, ἑπήκοον ἑαυτὸν παρέσνε ταῖς προλεχθείσαις ἰκετηρίαις. Εἶθ ὥσπερ σημεῖον δίδωσι διὰ τοῦ προφητικοῦ πνεύματος τῇ τοῦ δεηθέντος ψυχῇ, περὶ τοῦ εἰσηκοῦσθαι αὐτήν. Ἡ δὲ, συναισθομένη, μεταβάλλει μὲν τὰς ἱκετηρίους φωνὰς εἰς εὐχαριστίαν, ἐγνωκέναι δὲ ὁμολογεῖ τὴν γενομένην αὐτῇ εὐεργεσίαν· διό φησιν· Εύλογητὸς ὁ Θεὸς, ὅτι εἰσήκουσε τῆς φωνῆς τῆς δεήσεώς μου. Κύριος βοηθός μου καὶ ὑπερασπιστής μου· ἐπ' αὐτῷ ἤλπισεν ἡ καρδία μοι καὶ ἐβοηθήθην. Εὐσέβιος ὁ Καισάρειος, Ὑπομνηματα Ἐις Τους ψαλμους. ψαλμος ΚΖ'

Blessed is God, who heard the voice of my prayer. The Lord is my helper and protector, in Him my heart hoped and I was helped. My flesh reflourished and from my own will I confess it to you. 1  God is no deceiver, He is faithful to His promises, by which he has given promise, saying, 'Even while you are speaking I will say to you, Behold,  I am beside you.' 2 For near He is to everyone who calls with a pure heart and not far may He be from those who take to prayer, He himself listening that He be beside those who will call on Him in prayer. And then by sign given, through the prophetic spirit of the praying soul, he who prays knows that he is heard. And by this understanding the voice of the supplicant turns to thanks. As he says: Blessed is God, who heard the voice of my prayer. The Lord is my helper and protector, in Him my heart hoped and I was helped. Eusebius of Caesarea, Commentary on the Psalms, Psalm 27 1 Ps 27.1 2 Is 58.9
