Thats why heaven will be so wonderful the Christian. To worship God in heaven will be the fulfillment of our joy. Is it not true that when you admire something you praise it? "Isnt she beautiful!" or "that was amazing!". You are right in saying that He is "more beautiful than we can probably imagine." In fact, John said it first:

John 17:3 - And this is eternal life, that they know you the only true God, and Jesus Christ whom you have sent.

The children of God will spend an eternity of eternities chasing down the beauties of the divine Godhead. The very nature of God will throw us into such ecstasy that unless we were supernaturally strengthened, we would be destroyed by our own joy, unable to contain the beauty revealed. Our joy (and pleasure) while in heaven will be full in Christ, yet deepen for all eternity, even after thousands of revelations, because we are finite creatures.

Psalm 16:11 - You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore.
