Jesus' omnipresence

Elise has been asking A LOT of theological questions lately...nearly everyday.  Of course, Bryant is in heaven with all of this.  A sample:

(Driving in the car with Elise a few days ago)
Elise: How many Jesuses are there?  Is there only 1 Jesus or are there a lot of Jesuses?
Me: There's only 1 Jesus.
Elise: Is Jesus in the car with us right now?
Me: Yes, he is, but you can't see him.
Elise: Is he in those other cars?  And those houses?
Me: Yes
Elise:  NOOOO!  You said there is only 1 Jesus!  How can he be in our car AND the other cars and houses!

(Last night, all 3 of us were cuddling in bed together because it was cold)
Elise: Can you remind me again why there is only 1 Jesus but he is everywhere?
Bryant: (explains things and then we get into a long theological conversation again)
Elise: (cuts off Bryant) Wait, what if we talk the WHOLE night!
