why worship god?

[Markos]

I'm sure that the majority of the opposition that has been made against atheism in all of our lifetimes is that there IS a god, however, what perplexes me (besides the obvious issue of there being no reason to agree with this) is why this would necessitate worship? If we assume for a moment that god does exist, why would we be obliged to worship him/her/it? After all, that something was created by something implies no logical reason for worship, If i created the whole being of another human I would not necessarily need to be worshiped for this as I clearly had my own intentions for doing so.

What reasons can you think of for or against this? because I'm at a dead end in terms of the intrinsic value of God, even if it were to exist. Thanks

From a Christian point a view, this question is a bit like asking "Just because your wife exists, it doesn't logically follow that you should love her." For the Christian, it's not a question of logically necessity, or even moral obligation; it is a question of the very nature of the relationship between God and humanity. And what is the nature of that relationship? It is one of God's grace towards humanity, and humanity's response to that grace. That response is what Christian's (should) mean by the word "worship". It is not a word solely to do with particular acts of devotion like prayer or praise (though those things can be acts of worship). Paul "defines" worship in Romans 12:1 (NRSV) as follows:

"I appeal to you therefore, brothers and sisters, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship."

So, Christian worship is the response to the mercies of God of a whole life lived as an offering to God. Of course, the obvious question is this: why is a whole of life of this sort of worship the proper response to God's grace? It is because of the costly nature of that grace, which means that an uncostly response does not take God's grace seriously:

"Costly grace is the treasure hidden in a field; for the sake of it a man will gladly go and sell all that he has. It is the pearl of great price to buy which the merchant will gladly sell all his goods...Above all, [grace] is costly because it cost God the life of his Son...and what has cost God much cannot be cheap for us. Above all, it is grace because God did not reckon his Son too dear a price to pay for our life, but delivered him up for us." (Dietrich Bonhoeffer, The Cost of Discipleship)

So this is the "rationale" for worship - not a logical requirement or a moral obligation to show an abstract god that we acknowledge his existence, but a concrete response to God's concrete expression of himself in the life, death and Resurrection of Jesus.
