Thinking of Heaven will motivate us to live each day in profound thankfulness to God: “Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe” (Hebrews 12:28).
In Perelandra, C. S. Lewis’s protagonist says of his friend Ransom, who has recently returned from another planet, “A man who has been in another world does not come back unchanged.” A man who gives sustained thought to another world—the Heaven where Christ is and the resurrected Earth where we will live forever with him—also does not remain unchanged. He becomes a new person. He’ll no longer fill his stomach with stale leftovers and scraps fallen to a dirty kitchen floor. He smells the banquet being prepared for him. He won’t spoil his appetite. He knows what his mouth is watering for.
