In today's Gospel reading from John 14: Jesus said to his disciples, "In my Father's house there are many dwelling places. If there were not, would I have told you that I am going to prepare a place for you? And if I go and prepare a place for you, I will come back again and take you to myself, so that where I am you also may be. I am the way and the truth and the life. No one comes to the Father except through me."
All I can say is that Jesus knew exactly what he's talking about. We'd better believe.
