“In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.”
King James Version (KJV)
14:2 In my Father's house are many mansions - Enough to receive both the holy angels, and your predecessors in the faith, and all that now believe, and a great multitude, which no man can number.
Joh 14:2 In my Father's house are many mansions. By the "Father's house" is meant the heavenly abode. He is about to return there, from whence he had come. I go to prepare a place for you. If the separation was to be an eternal one, he would have forewarned them. Rather, he goes before to prepare a home for them where they can all be together. The departure of Jesus was needful to open an entrance to them and use.
