If we find ourselves with a desire that nothing in this world can satisfy, the most probable explanation is that we were made for another world. (C. S. Lewis, 19th century British academic and Christian apologist)
We are born we all kinds of desires, and most of them are satisfied as we grow and have experience. Channeling those desires into appropriate venues will bring satisfaction and contentment. But, as Lewis suggests, there may be an innate, unsatisfied longing that cannot be filled by any of life’s experiences. There is an eternal void that longs for eternity.
[God] has made everything beautiful in its time. He has also set eternity in the human heart (Ecclesiastes 3:11).
