Christians are living letters from Christ.  God gives us the power to tell others about God's grace and love.  Our only power and success comes from God.  Bufe talks about Moses and how he led the people out of Egypt.  He talks about how Moses' face would shine with the glory of God after speaking with God.  If Moses' face shined during the time of the Law, shouldn't our faces shine even more in the age of Grace with the Holy Spirit living within us?  Do you brightly reflect the wonderful glory of God?
