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. (John 14:3)
There is a beautiful, stark simplicity to these words of Jesus: 'I am going and I will be back.' He went. So he must come back. There is no need to worry or panic; he told us to trust him and not to allow ourselves to get disturbed and troubled (verses 1-2). He said he would go: he did. He said he will come back: he will. Jesus said it; I believe it; that settles it.
