Romans 10:14

14HowΠῶςthenοὖνshall they callἐπικαλέσωνταιon [Him]εἰςwhomὃνnotοὐκthey believedἐπίστευσαν;Howπῶςnowδὲshall they believe on [Him]πιστεύσωσινof whomοὗnotοὐκthey have heardἤκουσαν;Howπῶςnowδὲshall they hearἀκούσωσινapart fromχωρὶςpreachingκηρύσσοντος;

How then can they call upon One in whom they did not believe? And how can they believe in One of whom they did not hear? And how can they hear apart from one preaching?
