Why not Change the World?

Why not Change the World? I've seen or heard this expression quite frequently over the past four years. The sign you see here is from the entrance of Handong Global University, where I've served throughout that period.

"Why not Change the World?" is a challenge for all who follow Jesus Christ. It's more than just a slogan; it should be a way of life. Whenever we leave this world, it should be a better place than when we entered it. We need to continually be salt and light for those around us, regardless of where that may be. How will you change the world in 2009?
