"Don't let your heart be troubled. Believe in God. Believe also in me. In my Father's house are many homes. If it weren't so, I would have told you. I am going to prepare a place for you. If I go and prepare a place for you, I will come again, and will receive you to myself; that where I am, you may be there also. 4 Where I go, you know, and you know the way." [ John 14:1-4 ]
Yes, I know. The place He is preparing will come down with Him LATER, when He returns to set up His kingdom on earth.
Revelation 21:1-4
Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea. Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, “Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God. And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.”
