I've argued recently in other threads that, if He exists, God's actions are at least "correct" regardless what any of the other beings of the universe think about them. That is - they are correct by definition, because He is God - infinitely capable and knowing, etc. He basically defines "correct".
However, that is entirely different from God being "beneficial" to any particular being. And so, any "good" God supposedly does is completely relative to an individual experiencing whatever it is. Take for instance a claim I heard recently that, upon exiting the grocery store, a Christian friend of mine witnessed the rain halt at exactly the moment they personally walked out the door. This made them happy, and they thanked God for it. However, not as lucky were the 100-200 people who walked out of the store before this person, who were showered with rain unabashedly - and statistically, a percentage of those people were also believers, and a percentage of those believers probably would rather not have been drenched that day.
Personally, I feel it completely warranted to hold to a certain ignorance (as in, a propensity to ignore) of God if you find that belief in Him is in no way beneficial or valuable - which is exactly what I have found. The believers I meet offer me no real understanding of the benefits to be had via a relationship with their deity, and the universe as it stands offers no manifestations of "good" (as it relates to myself) that are uniquely attributable to a supreme power.
If spending my time in reverence to a supposed "God" produces no good for me, then why waste that time?
