'On that Day' in the Bible

Many will say to me on that day, "'Master, Master, have we not prophesied in Thy name, and in Thy name expelled demons, and in Thy name performed many mighty works?'

"On that day, if a man is on the roof and his property indoors, let him not go down to fetch it; and, in the same way, he who is in the field, let him not turn back.

when He comes on that day to be glorified in His people and to be wondered at among all who have believed, including you--because you believed the testimony which we brought for your acceptance.

From this time onward there is reserved for me the crown of righteousness which the Lord, the righteous Judge, will award to me on that day, and not only to me, but also to all who love the thought of His Appearing.
