There is a strong sense within our hearts that there must be more to this life than just this life. As the writer of Ecclesiastes says, God has “set eternity in the hearts of men.” We can try to ignore this longing or bury it under a flurry of activity, but in our quietest moments, that still, small voice can be heard. The reason why we often don’t feel at home in this world is that this world is not our ultimate home.
