Every year you grow you'll find Me BIGGER

From Prince Caspian by C.S. Lewis,

“Welcome, child,” he {Aslan} said
“Aslan,” said Lucy, “You’re bigger.”
“That is because you are older, little one,” answered he.
“Not because you are?”
“I am not. But every year you grow, you will find me bigger.”

If He's not bigger, you're not growing.
