The Saint writes:
So for that reason one should, in fact, fish well and diligently,just as the Lord foretells and teaches, saying, 'Follow me, and I will make you fishers of men,' and again through the prophets: 'Behold, I am sending forth many fishers and hunters, says the Lord,' et cetera. So it behoves us to spread our nets, that a vast multitude and throng might be caught for God, and so there might be clergy everywhere who baptized and exhorted a needy and desirous people. Just as the Lord says in the Gospel, admonishing and instructing: 'Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always to the end of time.' And again he says: 'Go forth into the world and preach the Gospel to all creation. He who believes and is baptized shall be saved; but he who does not believe shall be condemned.' And again: 'This Gospel of the Kingdom shall be preached throughout the whole world as a witness to all nations; and then the end of the world shall come.' And likewise the Lord foretells through the prophet: 'And it shall come to pass in the last days (sayeth the Lord) that I will pour out my spirit upon all flesh, and your sons and daughters shall prophesy, and your young men shall see visions and your old men shall dream dreams; yea, and on my menservants and my maidservants in those days I will pour out my Spirit and they shall prophesy.' And in Hosea he says: 'Those who are not my people I will call my people, and those not beloved I will call my beloved, and in the very place where it was said to them, You are not my people, they will be called 'Sons of the living God'.
