God’s Glory

How sweet all at once it was for me to be rid of those fruitless joys which I had once feared to lose! ... You drove them from me, you who are the true, the sovereign joy. You drove them from me and took their place, you who are sweeter than all pleasure.
Augustine

God would be unrighteous (just as we would) if he valued anything more than what is supremely valuable. If he did not take infinite delight in the worth of his own glory he would be unrighteous. For it is right to take delight in a person in proportion to the excellence of that person's glory.
John Piper Desiring God pg. 32
