First of all, God doesn't need anything, including worship. He doesn't need to be affirmed or have his ego stroked. He is sufficient in Himself.

It is true that He calls us to worship Him, but noting the above, we conclude that it is for our benefit, ultimately, not His. It appears that part of being a human being, and thus made in His likeness, is to recognize and appreciate beauty, righteousness, justice, holiness, and love. We see a lovely sunset, and we express our joy at contemplating its beauty. We observe an act of selfless giving, and our heart responds. We honor those who have achieved notable successes.

As we contemplate God, as revealed in the persons of the Father, Son, and Holy Spirit, there arises within us a desire to respond to what we see, unless we are so scarred and blinded by sin that we don't appreciate the wonder of who He is. Why did He make us this way? Ultimately, it is for our own good. This act of response to who He is, as we worship Him in words, song, and even actions, comes back to us and gives us a joy and satisfaction that none of the animals can experience. God desires this for us because He loves us.

However, because of sin, we are fully capable of worshipping "idols" - anything else but Him, including His creation, His gifts, ourselves, even Satan. When we do so, we see the terrible consequences in ourselves and in our world, as well as dishonoring Him.

To sum up: God doesn't need to be worshipped; He has given us the privilege of doing so, for our great good. This is why the first question and answer of the Westminster Catechism is so often quoted: What is the chief end (purpose) of man [sic]? To glorify God and enjoy Him forever. Worship (giving glory to God) and joy (in us) go together.

Keep asking, Paul, and when you have a full answer to your question, send it to me!
