Some mock the idea that God is so big that he fills the universe. God doesn't fill the universe. God is bigger than the universe! <ref>[[1Ki 8:27]] But will God indeed dwell on the earth? behold, the heaven and heaven of heavens cannot contain thee; how much less this house that I have builded?</ref> When God separated heavenly stuff from earthly stuff, the stuff the universe is made of, the earthly stuff was a void within God. <ref>[[Ge 1:2]] And the earth was '''without form, and void'''; and darkness [was] upon the face of the deep. And the Spirit of God moved upon the face of the waters.</ref> Christians have the idea that God took absolutely nothing, and changed it's nature to be something, then organized the something into stuff.  The picture painted by Genesis is that in the beginning there was only God. He was all that there was. There was no place to put a universe, so he opened a void in himself. He then made stuff from the immaterial void. The universe is still void. He formed stuff from the holes within himself. We are immersed in him.  :[[Ac 17:28]] '''For in him we live, and move, and have our being'''; as certain also of your own poets have said, For we are also his offspring.</ref> We are immersed in God like fish in water and birds in air. We cannot and never will be able to see him. He is Holy, separate, and different. He must make himself known in some way. There are tree testimonies in heaven.
