Jesus is saying that there are many people who profess to be Christians, who use the name of Christ, and who call Him by His exalted title “Lord” but actually are not in the kingdom of God at all. They do not belong to Him and will not be able to stand at the last judgment. The terrifying aspect of this is that these people are not on the fringes of the church. Rather, they are immersed in the life of the church, heavily involved in ministry, and perhaps have the reputation of being professing Christians. Yet Jesus doesn’t know them and will banish them from His presence.
