John Gill Commentary John 14:3

"And if I go and prepare a place for you, I come again, and will receive you unto myself; that where I am, [there] ye may be also." — John 14:3 (ASV)

And if I go and prepare a place for you
Seeing I am going to prepare, and will prepare a place for you, of the truth of which you may be fully assured:

I will come again ;
either by death or in person a second time, here on earth:

and receive you unto myself ;
I will take you up with me to heaven; I will receive you into glory;

that where I am there you may be also :
and behold my glory, and be for ever with me, and never part more.
