The birds are going to fly regardless of if someone tells them they ought not fly. They will fly because it is a part of their very essence. They see the other animals, the frogs who jump, the dogs who chase their tails, the humans who walk along the sidewalk. They see, but they do not want what the others have. They will always fly. Were they to forsake flying, they would forsake their very identity. 

I love the birds because they know who they are. 

And who am I, but His. Who are we, but children of the Most High King. 

Just as the birds were created to fly, I was created to be His. 

I will always be His. 

Our identity is simple, really.
