Right. I used to just say: God is.
Now I use a couple of scriptures to say that while God is, He is also all.
Can any hide himself in secret places that I shall not see him? saith the Lord. Do not I fill heaven and earth? saith the Lord. Jeremiah 23:24
Yes, yes He does.
Then also:
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. Acts 17:28
Though, all is God, God also exists outside of time and space.
For those who have experienced the oneness with God also find that there is no time or space, but are just useful constructs for me/us... all the me-s. Nevertheless, these persons can be anywhere at anytime in Spirit.
But, of course, you already know these things.
