When a child learns that G‑d struck the Egyptians with a mighty hand, no matter what his teacher may attempt to explain, he imagines a mighty hand reaching out of the sky. Because that is the world of the child.
When a child learns that Abraham argued with G‑d, no matter what his teacher may explain, he imagines Abraham speaking with G‑d like a man speaking with his friend. Because that is the world of the child.
When the child grows older, he will understand that G‑d does not have a body in the way that any creature has a body.
Growing yet older, he will understand that G‑d does not have an existence in the way that any other entity exists. He will learn that G‑d is infinite and unbounded.
And yet, when he was a child, he learned the truth. Only truth.
Because in the world of a small child, a mighty hand stretched out from heaven is the power of the Infinite.
Indeed, in the simplicity of the child’s imagination is a truth the adult can only envy.
