Throne refers to a place of power which God demonstrably has. There most likely isn't a literal throne made by a carpenter that He sits on. Sometimes things are illustrated in such a way to give example of God's glory in ways we as people can easily understand and digestOh really? Then how come that he "sits" on the throne and "laughs"? In the same context of Ps. 2? I don't know any spirit with buttocks to sit and a sense of sarcasm to laugh at the plotters.
Also, regarding the potter and the clay, it was most definitely spoken in a literal sense, God, in another instance, didn't give Jeremiah a torah lesson of Gen. 2, instead He led Jeremiah to a real potter's studio and used real pottery work as an analogy. God himself was anthropomorphizing.
This is the word that came to Jeremiah from the Lord: “Go down to the potter’s house, and there I will give you my message.” So I went down to the potter’s house, and I saw him working at the wheel. But the pot he was shaping from the clay was marred in his hands; so the potter formed it into another pot, shaping it as seemed best to him. Then the word of the Lord came to me. He said, “Can I not do with you, Israel, as this potter does?” declares the Lord. “Like clay in the hand of the potter, so are you in my hand, Israel. (Jer. 18:1-6)
For example, the heavens are the throne of God and the earth His footstool. Same thing is never said of Jesus by the way, but we know that the heavens are actually outer space and the earth is a planet. We know this isn't literal.
However, are humans made of clay? Arguably, yes. We are not clay, but we contain many of the elements and minerals one may find in clay. Clay may also just be a way of saying people are physical beings made out of matter and matter can take on so many different forms.
So are we chocking this up to that you and I believe differently what is literal and what isn't in the Bible?
