Faith And Salvation

Θαρσεῖτε, ἐγώ εἰμι    Εἰπὼν, Θαρσεῖτε, τὴν πίστιν ἀπαιτεῖ· δι' ἧς ἔκαστος τῶν εἰλικρινῶς εἰς Χριστὸν πιστευόντων σώζεται· ἐπαγαγὼν δὲ, Ἐγὼ εἰμὶ, λύει πάντα φόβον· Ἐγὼ γὰρ, φησὶν, εἰμὶ, ὁ πάντα δυνάμενος ποιῆσαι. Ἅγιος Κύριλλος Ἀλεξανδρείας, Ἐξὴγησις Εἰς Τὸ Κατὰ Ματθαιον Εὐάγγελιον Source: Migne PG 72.419

Be of cheer, I am. 1 Saying 'Be of cheer', He sought faith, by which He saves each one who believes sincerely in Christ. And then He adds, 'I am' and dispels all fear. 'I am,' He says, that is: I am He who can do all things. Saint Cyril of Alexandria, Commentary on Matthew, Fragment 1 Mt 14.27
