Jesus tells us what He expects from us on the Day of the Rapture in the following Scriptures:

Revelation 3:3
"Therefore, IF YOU WILL NOT WATCH I will come upon you as a thief, and YOU WILL NOT KNOW what hour that I will come upon you."

Revelation 3:11

"Behold ! I AM COMING QUICKLY !  Hold-fast to what you have that no one may take your crown."

Revelation 3:15-16

"I know your works that you are neither cold nor hot. I wish you were cold or hot. So then because YOU ARE LUKEWARM, and neither cold nor hot, I will spew you out of My mouth."

Hebrews 10:37-39

"For yet a little while He who is coming will come, and will not tarry  (when he comes). Now the just shall live by faith, BUT IF ANYONE DRAWS BACK My soul has no pleasure in him. But we are not of those who draw-back to perdition, but we are of those who believe in the saving of the soul." 

SO, THERE YOU HAVE IT:

Jesus has certain expectations of us on the Day of the Rapture. He expects us to be watching for Him to appear on that Day because we have been given that information in the Book of Revelation .  When Jesus comes, He is coming quickly, so be ready for Him.  Jesus does not want us to be lukewarm about His coming but rather to be excited while expecting Him.  Jesus does not want us to draw-back for any reason.  DO NOT DISAPOINT THE LORD ON THE DAY OF THE RAPTURE !

According to Your Word, come Lord Jesus !
