Most of us are materially blessed enough that we can pretty much get whatever we want, whenever we want (within reason). Our comfort makes our lives convenient, enjoyable, and relaxed.
But comfort can also be a curse. It makes us believe our lives should be all about catering to our own needs and fulfilling our own desires. We lose sight of the needs of others and forget the less fortunate. And the slightest inconvenience to us feels like the end of the world.
Comfort is like a drug; we always want more. But living in comfort, safety, and apathy is exactly the opposite of how Jesus taught us to live.
