What is God's Real and Greatest Glory?

This is a vital question, and it resolves into important sub-questions, which, in turn, imply some things about theological systems.

1)  Is it God's greatest glory that he is served by his creation, or that he serves his creation?  Who made whom?  Who sustains whom?  Who saves whom?  Who feeds whom?  Who is the only giver?

2)  Is it God's greatest glory that he creates, or is it his greatest glory that he saves?  Is salvation Plan B, to fix up Adam's Fall, so that Plan A can proceed?  Or, is the provision of salvation really Plan A?  Which redounds to the greater glory of God?

3)  Is it God's greatest glory that he legislates obedience, and achieves that control over his creation which he originally intended, in spite of the Fall?  Or, is it that he forgives sin, and creates a new people, giving them the gift of the Spirit?  Who has the "name above every name" in all the cosmos, and what did he achieve to get it?  What is God eschatologically thanked for (Rev. 5).

The answers to these questions are intensely practical, and inform all our dealings with God.

There is also controversy here.

Some try to say that emphasizing salvation like this is man-centered, and that our religion should instead be God-centered.  His glory should be the highest thing, and not even our own salvation.

But, the Scriptures are plain that His greatest glory is to be the Savior and Sustainer of the world he has made -- the Taker of Nothing and the Giver of All.
