We are earthbound creatures. We are transfixed on what we see around us. C. S. Lewis, in Mere Christianity, reminds us that we are meant for a fuller existence, and that there is a reality we cannot see fully now, but if submitted to God and His will, forgiven of our sins and living righteously, we will see it. He also deals with a common misconception:
Most of us find it very difficult to want “Heaven” at all—except in so far as “Heaven” means meeting again our friends who have died. One reason for this difficulty is that we have not been trained: our whole education tends to fix our minds on this world.
Another reason is that when the real want for Heaven is present in us, we do not recognise it. Most people, if they had really learned to look into their own hearts, would know that they do want, and want acutely, something that cannot be had in this world. There are all sorts of things in this world that offer to give it to you, but they never quite keep their promise. . . .
If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.
I’ll just simply add “amen.”
