As I was driving to Mass this morning, my thoughts wandered at random. If you assume that God does not exist, and yet when you do something bad, deep down you still sense that somehow it's wrong, then I say that the assumption must be incorrect. The reality of conscience is proof that God exists. Otherwise, we just do whatever we like to keep ourselves happy and nothing should bother us. Without conscience, we would have destroyed each other long ago. The existence of conscience points to the existence of salvation. Today's Response to the Psalm, Matthew 4.4, "One does not live by bread alone, but by every word that comes from the mouth of God" is appropriate. To live by bread alone is to be self-centered, while to live by the word of God is to be saved.
