Back in college, I was attending church for the Ash Wednesday service, and the priest's sermon really touched me. He stated that the Lenten season wasn't so much about giving something up, or "fasting" as it was about doing things which remind us of what it is to be Christian. While fasting is a good fallback, he actually suggested that we spend this time doing more, working harder to be good Christians, rather than just giving up something. We should take this time to give of ourselves. Perhaps giving up what we prefer to spend time doing, in order to make the lives of our fellow humans better. Giving up our comfort, giving up our easy life, just to make things better for some others.
