Today is the 40th anniversary of the Space Shuttle Challenger disaster. It’s one of those moments you might remember what you were doing when it happened. I was at home in Minneapolis making music, and later learned about the tragedy while watching TV. It serves as another reminder that one must be prepared for eternity, as we are unaware of what tomorrow holds. “For what is your life? It is even a vapor that appears for a little time and then vanishes away.” (James 4:14)
