It is true that one mistake can cost one his whole life. Around three dozen inmates were present at today's prison Communion service. Not all of them were career criminals; some might have made just one wrong move and ended up getting locked up for life. But there's always one bright hope for all of us. By turning our hearts to the merciful God, we can still get to enjoy eternal life later. In sum, one right move can wipe out what all our mistakes cost us.
