The smallness of God exists in the fact that electrons, tiny as they are, are still not the smallest particle-waves that we know of. If God were not small, He wouldn't be able to support small things in the perfection of physics.
The Jewish People had a History with Egypt and its Neighbors.

What we forget is that Jesus was part of Ancient Israel. He was the most stubborn of all of them, but stubborn in righteousness. Jesus was so stubborn that He wouldn't stay dead when they killed Him. And He is still alive today.
The Prophets talk about Things that Happened. And they had been involved with the Chaldeans and the Assyrians. In Egypt. Then Hezekiah is attacked by Sennacherib and the King of Kush comes out to challenge him, and 180,000 Soldiers are Killed, then Sennacherib. This is all Years after Egypt. And Genesis Ends with Joseph being Vizier in Egypt. Then after that, the Prophets are Talking about what Happened after Joseph.
And here we are today. Did the prophets talk about us?
The whole thing is about what God is doing and has been doing for all of us. This life goes away in, say, 100 years, for all of us. It is simply a preparation for a wonderful life in the Hereafter, for those who are on God's side. The joy of the Lord is your strength, so that you can be stubborn enough to rise from the dead like Jesus.
