"All Israel shall be saved (Rom. 11:26), all Israel, that is, the true Israelites, like Nathanael, of whom the Lord said: “Behold, an Israelite indeed, in whom is no guile!” (John 1:47). These are the Israelites who will be saved. The majority of Jews, because of their cunning and countless unrepented evil deeds, will perish. Change quickly with a good change, every Christian, as long as the doors of God’s mercy are not closed to you. Do works of mercy, while it is day; the night is coming, when no one can work (John 9:4)."
