One of my favorite Matt Chandler sermons has at its thesis that you’re miserable because you think that the world revolves around you. The remedy, of course, is to revolve your world around Christ and experience some freedom. You see, if the world revolves around you, then every impediment to what you want results in anger on your part. But if it’s not about you, then you’re free to relax, to think of others, and to enjoy life.
A friend shared this video with me. It does a great job of illustrating the same concept, but from a secular perspective.
