He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty (Psalm 91:1)
Where else could one dwell? In the world. Believing one is a body, where survival is contingent and even going outside in sunshine could, in the long run, be deadly.
In the world, one is not 'under the shadow of the Almighty'.
If God really is everything, what one is under, in the world, is the shadow of death, nothingness, the void, the abyss, the endless endlessness beyond the end of the Almighty, except the Almighty has no end, so that endlessness does not exist except in imagination.
Sink all the way down, all the way in, and, there, God is found.
