God promises a joy beyond comprehension. "Ah", you say, "but I can't comprehend it, so I'll settle for what I can get in simple distractions." Do you have to comprehend it to know it? I can't comprehend the universe, but it is stunningly beautiful if I only take the time to look. Fool you are that you would settle for less!
As Lewis says, "“Joy is the serious business of Heaven.” That means I need to invest in my joy, not wait for it on a cookie plate. The Bible says "A fool takes no pleasure in understanding, but only in expressing his opinion!"
So let me not be easily satisfied by the world's entertainment. Let me instead hunger for the depths of Joy, and run the race with ALL my heart, soul, mind, and strength. It is the fullness of Joy I desire, and not the toys of childhood.
