Sometimes a skeptic will throw down an objection that really causes the questioned to pause. This objection is one of those objections. “Why should I worship a God who is self-centered and conceited because He created an entire Earth and universe just to sit around and worship Him?”
If this objection had any validity, I don’t think I would want to worship that kind of God either. Would you? There has to be an underlying issue to our worshiping a Creator Who got things started from the start of the universe to what we see around us today.
Let’s posit this question: If we are created to worship God and enjoy Him forever, like the Westminster Catechism states, what does our worship do for God? Does our worship really affect Him in any way? Is this God we worship somehow better because humans have been worshiping Him?
Just so we know this one thing right out of the gate. God is not encouraged, or enlarged or changed in any aggrandizing way just because we have worshiped Him. God receives no benefit from our worship.
What does worship do? Worship relates to God’s own self-knowledge and His comprehensive understanding of us. God must treat Himself as the greatest good because He IS the greatest good. He is perfect in His being, based upon His nature, apart from any function that is related to us.
Let’s assume for a moment that God treated something else as the greatest good. If this were the case He would no longer be God, and He would be no longer affirming the truth about Himself, because something else would be the greatest good and not God. So it is not wrong for God to treat Himself as the greatest good. He is not the one who benefits from our worship. Instead, our worship of God allows us to see Him as He is, and so continue the extension of His love and goodness in creation.
