Where is my imagination body part?

We were in the truck driving to the grocery store and this was the conversation:

Peyton: Where is my imagination body part?

Mommy: It's in your brain

P: It's in your brain? How is it in your brain?

M: That's where God put it.

P: Why do we have ears?

M: To hear.

P: Why do we have eyes?

M: To see.

P: Why do we have a nose?

M: To smell. Why do we have a heart?

P: So Jesus can live in it.

I make a lot of mistakes as a Mom, but I've obviously done something right. You can imagine my delight when he said this. It didn't come up during prayer time or driving to church. This is something he believes and knows to be true, and he thinks about it even while driving to the grocery store.
