Who has naming rights to ME? s28e13 Jn1:42

Wouldn't it be cool to meet God and have Him give you a new name?  It happens to Peter right at the beginning of their relationship.  Peter hadn't even expressed any hint of belief yet.  God says to the biggest knucklehead of the Bible: You are ROCK. You will grow strong and solid. It is such a wonderful gift from God to see Peter in this way, even before it happens.
