Children want to know where God is.
Honestly adults have trouble answering that questions also.
He is bigger than everything, yet the Bible usually speaks of God dwelling, acting and speaking with humanity in a single location because of our limitations to time and space.
I can be here now and somewhere else later, but God is always in both places simultaneously.
Eventually God sent Jesus as a baby in a manger, a sacrifice on the cross, and a victor over the grave.
Ultimately, though He did not come simply to dwell with us, but to prepare us to dwell with Him.
