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. And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also. - John 14:2–3
Sometimes we act as though everything and anything that can be done must be done while we are living here on earth. Of course, we want to make the most of our time, because we don't determine when we are born or when we die. But we do determine how we will live our lives. We also need to know that life does not end after our time on earth; it continues in heaven.
When a life is limited by disability or illness, when a life is cut short through death, we tend to think, Well, that is unfortunate. They never realized their dreams. But who is to say those dreams could not be realized on the other side? Who is to say that God would not complete on the other side what He has started on earth?
When we see someone who has lived a long life but has wasted it for the most part, and then we see someone with so much promise and ability and gifting who dies unexpectedly, we think it is so unfair. But that is because we are thinking about life on earth and not realizing that life continues on. For the follower of Jesus Christ, death is not the end of life, but a continuation of it in another place.
When you book a flight, sometimes you will have a stopover. I don't like stopovers myself, because sometimes things happen during stopovers. Bad weather can roll in, which can mean getting stuck there for some time. I like to get from point A to point B as quickly as possible.
For the Christian, earth is just a stopover. Waiting for us on the other side is heaven. And we will arrive there sooner than we may realize.
