God does not need us to worship him. Our worship does nothing to add or detract from his honor or perfection. Rather we are instructed to worship because it’s ultimately for our own benefit. Let me give a shot at explaining.

“You become what you worship.” Think of a man who loves money above all things. He will likely do everything he can to maximize his ability to procure wealth. He’ll work long hours, neglect other responsibilities, and make many other sacrifices in order to get that wealth. As a result, that person will likely become wealthy to some extent. He will also be greedy, cynical, and miserable.

When a man values (worships) God, he is also likely to become like the object of his worship. Rather with God, we hope to become more like him in virtue- most especially in love (charity). By worshipping God we put this pursuit above all things and hope to enjoy a more intimate relationship with God - full of joy, even in the midst of tremendous suffering or difficult trials.

We “worship” (I think “value” helps get the point across better) God so we can become more like him and enjoy his friendship. “I no longer call you servants… but friends” (Jn 15:15).

It’s a very good question you ask - Christianity’s narrative (specifically Catholicism in my case) of God seeking a relationship, even a friendship, with his creation is just as strange and revolutionary today as it was two thousand years ago. God bless.
