The text from your link; Matt 7:22-23 KJV:
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?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Yes, I believe there will be a lot of that.
And also a lot that will return to the Zeal of their First Love.
