The fact that you would call God useless is beyond arrogant. I'm not even going to bother arguing with you.
Okay, you have misrepresented yourself. You are clearly a theist. You are not agnostic.
And god
is useless, both as an idea, and as a highly unlikely reality.
Frankly, if I were to judge by the descriptions of at least the major, well-known god depictions, God's
impossible.
On a related note, I find that these days I look with great disdain upon those who, after some kind of accident or tragedy, urge everyone to pray for the victim.
If god had wanted that person to be safe, unharmed, uninjured, why did he not spare that person from the incident in the first place? Since god didn't spare the person, praying for his safety or recovery seems to be going against god's clearly expressed will.
Anecdotally, an example: My brother had had a major heart attack and was comatose for almost two weeks. His entire church prayed for him unceasingly. Finally, he woke up, though with very little memory of who he was, who his family was, or what had happened to him. Still, everyone said it was a "miracle," and god had spared him. There was much rejoicing that god had seen fit to save his life.
Two days later, the nurse turned my brother onto his left side while changing his sheets...and he had another major heart attack and died on the spot.
The church members were oddly silent. And god looked like total prick. Good thing I know he's imaginary.
