Well, if the term "God" has this connotation, I can agree. But the term "God" usually has a broader description. God is also the creator of this existence according to the believers.
Think of the word God like the word King. God's name is Jehovah. Jehovah may be my God but not your God. Charles may be your King but not my king. Jehovah is a god. Allah is someone else's God Charles is a king. The problem is simple. People wrongly think God is a name and gods are a copy. They think saying "God damn it" is taking the "Lord's name" in vain. I use the term think loosely.
So, you're right in part. If people stop worshipping a "God" then religions will have no reason for being because worshipping implies rituals and doctrines to follow up. Isn't it what religion is about?
Not really. The only reason for religion to exist is power, usually through money. Religion is pretense and ritual. Paying the man.
Nevertheless, the people will have this necessity of looking for a reason of their existence, so the need of a "God" will pop up anytime soon.
That's where the pretense comes in. Make believe. Just using God or gods or science or religion as a means to justify the ends. A make you look good to the people you want to look good for.
God's will. God is on our side. You can always tell a good god when he hates all the same people you do. Rally the troops! Don't question God. But God ain't them. Follow the science. Follow the money. Follow the god.
So, ya' gotta' ask yourself, what does it all matter? It doesn't. Just watch 'em destroy one another. Just like the very real Jehovah God told Adam they would.
So, I don't think it's enough to stop worshipping a "God" in order to get rid of this "God".
The stopping I mentioned wasn't to get rid of the God. Remember? I said it didn't matter whether or not God existed. It just means he wouldn't be a god anymore. God means worshiped. Not anything else. Anything and everything can be a god. Worshipped. You have to get the idea that God only means God. Sky magic make believe. God doesn't mean that. God means worshipped.
I think the only way to get rid of the GOD OF RELIGIONS is to know exactly the real nature of this existence. I mean, while it is true that the God of religions is a manifestation of human being's ignorance, we have to acknoledge too that we depend on a kind of FORCE or SOURCE that sustain us, which I refuse to call it God because it reminds me of religions. I'm pretty sure the knowledge about this FORCE or SOURCE can be explained scientifically and will satisfy all our doubts equally.
I know. No martyrs, right? But you're only recycling the same thing and calling it something different. Minus accountability and responsibility. It doesn't pay and it doesn't matter. It may make you feel like you're ahead of the game but you're in the same ship of fools as the "believers and sceptics." The ship's going down. It doesn't matter who goes down with it. It isn't a scare tactic, it's truth.
