Explaining God to a 3 year old

Katelyn, you think so deeply about everything it just amazes me that you are only 3 sometimes.  You had a lot of questions about heaven and God tonight on our drive home from Grandma and Pop Pop's house.  You asked how much it cost to get there.  You really wanted to go there to see what it is like, but you did say that if you went there you would never see your house again.  We talked about Gi Gi a bit also.  You asked if God was a real person or just pretend.  I told you that God was real, but he wasn't somebody that you see with your eyes, but rather feel in your heart, to which you replied that God must be in your tummy because you could feel him moving around in there and he would probably go in your test-ins (intestines) and then you would poop him in the potty.  You do crack me up sometimes!!  You asked me if God has a gf, and if he sleeps in a bed.  What his house looks like and if he has hands.  I love that you are trying to wrap your head around this in the way you do best - asking a million questions!
