I appreciate your continuance in this matter as I understand your reasoning, but I need to redirect you back to your premise. Although Jesus does go on to testify of the coming promise of the permanent indwelling Holy Spirit starting in verse 15, that was not all He was talking about from the onset of that chapter, so you need to reconsider that application.
#1) Jesus speaks of going to a place to prepare them a place which is in His Father's house.
#2) Jesus speaks of coming to them again to receive us unto Himself to that place so that where He is now, so will we be: which is New Jerusalem which will come down from heaven after the great tribulation.
Now although you have gone to great lengths in making the case that He was talking about the Holy Spirit, Jesus was testifying to where He is now that He will come to receive us so that where He is now, so will we be.
A traditional Jewish marriage ceremony, the newly married couple has the bridegroom leaving the bride for a time to prepare a place for her, and when the new home is ready, he comes to take her there.
We are married to Christ, and so this preparation to come to the wedding feast of the King is paramount for a believer to be His disciples by leaning on Him in being our Good Shepherd in helping us to continue in His words to be chosen from the many that are called to attend. That is why those with His seal are exhorted to depart from iniquity now so as to avoid being "destroyed" from being that vessel unto honour in His House into becoming that vessel unto dishonour in His House by being left behind to be cast into the bed of teh coming great tribulation.
Of this issue, we both agree of the necessity for a believer to trust Jesus Christ as their Good Shepherd to help them to continue to abide in Him and His words, and not just rest in Him as their Saviour for eternal life.
You may not see it yet, but the warnings Jesus keeps giving to believers cannot be applied to the warning given for the great tribulation. These two seperate kinds of warnings leads to two different judgments, and thus two different harvests. There is a need to watch and be ready now, because He can come at any moment... NOW.
Sure, He can come now...and the saints will be with Him when He does! You are still here( at least I am assuming that you are not sitting in heaven typing) So if He returns at this moment...as you say He could, how will you be coming with Him? There is only one way, one you die as a saint and are in the first resurrection, or are found worthy to stand before Him when He returns....Jesus isn't coming back twice . He is coming back once....to reign from Jerusalem. He comes on clouds remember and ALL eyes will see Him remember...It isn't going to be a secret rapture.
Act 1:11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
Rev 1:7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
