Why does God demand worship?

Amy Hall at Stand to Reason recently posted a piece called "How to Think About God Promoting His Own Glory." She explained that what is inappropriate for humans can be perfectly appropriate for God because of who and what God is. I thought it was a really good article on a subject that's very important to me, so I shared it with a friend and asked what she thought.

My friend pointed out that Amy had not actually explained why God demands worship even though she did raise the issue. I re-read the article and found that my friend was right. Amy had only explained that it would not be inappropriate for God to command us to worship him or why God has the authority to command us to worship him. She didn't actually explain why he does, though. So I thought I'd take a stab at it.

I didn't come up with this on my own, by the way. This is inspired by something Jonathan Edwards argued in his book/pamphlet, The End For Which God Created the World.

The reason God demands that we worship him is precisely because of his goodness. God is the greatest conceivable being. He possesses all holiness, goodness, glory, perfection, greatness, etc. He is the very standard of goodness, so he's as good as it gets.

To love and esteem that which is good, pure, beautiful, glorious, etc., is itself good. It is good to give credit where credit is due, respect where respect is due, etc. Worship is the highest form of praise, love, esteem, appreciation, etc.

Since God is good, he naturally loves that which is good and wants to promote what is good. And since God is the ultimate authority, he requires the good of us. Since it is good to worship the ultimate Good, and God is the ultimate Good, God demands that we worship him. He demands it because it is good for us to do, and because he is good.

That's it in a nutshell. I was thinking about this earlier today, and it occured to me that it presumes an answer to the Euthyphro dilemma. It's basically saying that God's commands flow from a pre-existing good. It is good to worship the ultimate Good; therefore, God commands it. But would it be good if God didn't command it?

I don't know. That's kind of an incoherent question because if the goodness of esteeming that which is good is something that is part of God's goodness or what it means to be good, then the hypothetical would have to be based on the notion that God was different than he actually is. Maybe we could say that Good consists of what God values, and God values goodness as well as the esteem of goodness. That's what makes it good, and he issues his commands for that reason--because it's in his good nature to command that we do good.
