what's in a name? calling?

considering calling (I.e., what it means that we're called by God) while also having fun with what 'what's in a name' and what it means to receive a nickname or new name (E.g., Simon being renamed Peter by Jesus) - pregnant with possibility, they can be poignant as well as prophetic.  E.g., at birth, The Rev. Dr. King was named 'Michael' Luther like his father. But, after an educational church trip to Germany in 1934, his father changed their names to 'Martin' Luther in remembrance of a great reformer of the church.
