You have left no room for argument whirlwind. The ones who are looking forward to a house made of chocolate, and place of delight in the sky, have missed the point that you presented here, and believe in tales and stories. There will be no heavenly "mansions" for anyone.
In the period of His return and reign His Father's house, the temple, will be a reality once more, and His disciple will find their places within it as appointed of God. They will perform divine service there as priests of the Most High God.
We are moved beyond that portion as members of Christ's body, to the new humanity, wherein God dwells in His people.
1C 15:28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
For His disciples, their abodes (mansions,KJV) will be in the temple in the new Jerusalem, with God dwelling among them. We already are the temple of the Holy Spirit, and God already dwells in us. The situation for us far surpasses that which was promised to His disciples in John 14:2-4.
2C 6:16 ... for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in [them]; and I will be their God, and they shall be my people.
Our blessings are in the celestial realm, and the blessings on earth will be enjoyed by the elect of Israel. There is a glory terrestrial and a glory celestial, and by mercy, grace and faith, we have obtained the latter.
