If your God leaves you, then?

In the holy book of Christians named Gospel of Mathew, Chapter 7, verse 22 to 23, Jesus Christ advised his people that “Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? And in thy name have cast out devils? And in thy name done many wonderful works (miracles)?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity”.

Do you know those people that who are they?
