John 14:1-3 is in no way a 'rapture to heaven' proof. The New Jerusalem; being built in heaven, comes down to earth after the Millennium.
Revelation 21:1-7 Then we Christians get to live in it for Eternity.
Here is the context of
John 17:15....
John 17:20 It is not for these alone that I pray, [the disciples] but for all those who thru their Words; put their faith in Me.
You are wrong and your 'rapture to heaven' is a false teaching.
Amen.
John 14:1-3 speaks of Jesus going to "prepare a place for you" where the saved "will be where I am" for eternity after his return with, that "Place" the Holy City, to this earth again.
The "many mansions" and "Place prepared" Jesus' death burial and RESURRECTION are the foundation of, "are prepared" from "before the foundation of the world".
The Lord Jesus predicted his coming again from the grave, and explained to the disciples HIMSELF, "No man comes to the Father BUT BY ME" - by the Way I Am, the Truth I Am, and the Life I Am. "I Am" - the Lord Jesus -, was the "Place I go to prepare for you ... so that WHERE I AM, ye may be also."
"If indeed ye be risen with Christ ... your life is hid with Christ in God ... where Christ sitteth on the Right Hand of God ... Set your affection on things above and not on things on earth ... for ye are dead..."
