John 14:2 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? 3 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.
Jesus is comforting his disciples— and yet he is the one soon to die a horrible death. But comfort them he does with the knowledge that he is going to his Father’s house to prepare them a ‘μονη’. This word was translated in the KJV as ‘mansion’, and gave rise to the idea that the reward for a good Christian life is one’s very own palatial home in heaven— the better you have been, the fancier your heavenly real estate will be. However, this is not a very good rendering of the word, which only appears twice in the New Testament— both times here in John 14. The other occasion is verse 23 where Jesus promises to come and make his ‘home’ with his disciple. And it is this idea of a ‘dwelling place’ or ‘home’ that best fits verse 2. Jesus is going to prepare ‘home’ for his disciples in God’s home. The idea is that God and his people will dwell together, at home, in his home.
So the comfort that Jesus offers his disciples is that he is leaving with the purpose of bringing them together again; so that they can be at home with him always. This is the comfort he offers. And this exactly what is described in the final scene of Revelation.
Rev 21:1 Then I saw “a new heaven and a new earth,” for the first heaven and the first earth had passed away, and there was no longer any sea. 2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3 And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God.
Rev 22:3 No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. 4 They will see his face, and his name will be on their foreheads.
