Let’s start with an antithesis. On the one hand, God dwells everywhere. Nothing could exist at all if it were not upheld immediately by God’s power. On the other hand: We cannot see; we cannot grasp; we cannot know God.
See? Antithesis. Both true. God everywhere. But everything we see, know, conceive: not God. Human beings search constantly for God, Who is everywhere.
Then: God began to work with us to help us deal with this problem. He drew close to the ancient Israelites. He gave them His holy name to invoke. He led them out of slavery to their homeland. He established a dwelling place with them. The Ark of the Covenant.
