'In that Day' in the Bible

Many will say to me in that day, 'Lord, Lord, have we not in thy name prophesied? and in thy name have cast out devils? and in thy name have done many miracles?'

Yea and I say unto you: that it shall be easier in that day, for Sodom than for that city.

"And in that day shall ye ask me no question. Verily, verily I say unto you, Whatsoever ye shall ask the father in my name, he will give it you.
