Who Am I ???

Luke, Sam and I were driving in the car and we started discussing animals that drink milk.  We had also been discussing animals that lay eggs.  I told Sam people drink milk, but don't lay eggs because we are mammals, just like pigs, cows, dogs, etc.  Sam of coure had to argue this because people are not the same as those other animals.  I was trying to convince him that we are still all mammals, when Luke spoke up and cleared up everything.  Luke said, "I am not a mammal, I am a Child of God."  Thanks Luke for keeping things in perspective.
