"My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am."
In the scripture above, Jesus says that he is going to the Father's house to prepare dwelling places for us. And that he is coming back to take us back with him that where he is we (believers) may be also. So at some point Jesus will return to come and take the church back to the Father's house, which could only be referring to heaven. The following is a detailed account of His return:
"For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. Therefore encourage one another with these words."
In the scripture above, the Lord descends from heaven and the dead in Christ are resurrected. Then those in Christ who are still alive will be changed and caught up with them in the clouds to meet the Lord in the air, where according to John 14:1-3, the Lord will take the entire church back to the Father's house.
Anyone who says they don't understand this is either purposely denying it because they've adopted the teachings of false teachers or there is definitely a veil over their spiritual eyes, because the scriptures are very clear in their meaning regarding this event.
I personally don't use the word "rapture" but stick with the original Greek "Harpazo" which means " properly, seize by force; snatch up, suddenly and decisively , force suddenly exercised." This is the same word used when Paul said that he was "caught up" to the third heaven and the same word used when the male child is "caught up" to God's throne and the same word used when Philip was "snatched away" from the Eunuch.
