"Why are we divided by those different Gods?"

Because we are human. God just gives us the opportunity to unite together in religion without forcing us. Our nature is to be divided. An irreligious group will find another exuse but Gods are as good an excuse as any for those benefitting from divisions even if God should bring us together. There have been exceptions. Look at historical Christian based European society that gave people the choice to pursue any religious belief they want (subject of course to countermeasures to deter instability due to infiltration into the government under the false pretence of being Christian) or Nihon where Buddhism and Shintoism reputedly coexist.

Ultimately the issue of Gods makes no sense unless you accept that there must be at least one God. The choice has to be made. If you are determined to reject the possibility of that something more then there is no point in relying upon the faith that something is impossible as a premise to assert that something that can't be explained based on that premise can be used to justify the original faith. Making some type of sense of religion requires a premise that God exists.

Reasoning can point to religion. Reason can help choose a religion. But you can't jump the middle bit and expect the end bit to make sense.

If God does not unite all mankind why?
Evidence is the opposite may be true why?
Is it to strengthen us by competition?
Evolution does that doesn't it?

"you can't jump the middle bit and expect the end bit to make sense."

Kind of like:

Step 1. Believe in God
Step 2. ?
Step 3. PROFIT!

And in my view you can not cling to the warmth of the God of your race, and kind, with total belief.
And say the God of those next door is a fable.
It divides man to do so.
Why?
Inside each of us is the joy of life.
A deep mystery we will forever wonder at.
And like a need we bought from the cave with us a wish to explain it all.
One God may unite us but it would still be the warm blanket.
Are we meant to know? maybe our children's children ten time removed , if we do not kill each other.

Belly.. sorry to hear about Skeeta.. our 'pus' will also go that way soon.. she is getting a bit frail..

Dickie...that was indeed a beautiful poem mate!

MJBP.. ok.. you ask "why we are divided by those different gods"?

I can answer that, but you might not find my answer completely satisfiying.

On the one hand.. we have 'God reaching down to man'. "Abraham, Israelites, history of Israel.. Christ..New Testament.. the Church"

On the other hand.. we have 'man reaching up to God'.. idolatry, various isms.... inventions...paganism, shamanism.. animism, Islam, Sikhism, Hinduism etc.

Then.. there are philosophies.. "Buddhism, Confucionism" and others.

So..the issue really boils down to "in which faith has God really spoken to and reached out to man" ?

Well.. based on the clear evidence, I have to say iit is my first example.

To Abraham, and his offspring.. the Israelites through the prophets..and finally in Christ.

Only a careful study of the issue will confirm or deny this.

Bugsy is quite correct when speaking about the likes of Benny Hinz and his ilk....but not correct about Jesus and the values he imparted to his disciples, and the early Church.
So....Bugsy.. why not look at Jesus.. rather than the slimey miscreants who claim his name to make money ?

"If God does not unite all mankind why?"

Because God gave humankind free choice. Because it is fallen human nature to be divided. Because it is politically expedient for some people to have divisions and they can be quite influential. Like most things it is multi-causal. But it isn't fair to disobey and reject someone then blame them for the result of such behaviour.

Evidence is the opposite may be true why?

Because that is the way that evidence works. You need to weigh up the evidence and make a reasoned conclusion. I'd submit if you step back and look at it objectively you won't help but appreciate the positive contribution that God (real or otherwise) can make and prove the negative contributions to be a self serving artifact of humans not a logical corollary of (what has been put forward rightly or wrongly as) God's revelation.

"Is it to strengthen us by competition?"

Boazy gives an alternative theory below that sounds plausible. And while I'm at it ditto re: Benny Hinn comments.

"Evolution does that doesn't it?"

Theoretically.

And in my view ...

Would you be willing to drop your barriers enough to consider it as a hypothetical? What if your God is real and those next door are fables? What if your God teaches you to give those who want to live with fables free choice? Does it make sense to you as a hypothetical?

"It divides man to do so."

It divides humans more if they don’t. Many religions have positives in them and enable less division.

"One God may unite us but it would still be the warm blanket."

Or an eternal omnipotent creator. Your faith reminds me of a book title I saw. "I don't have enough faith to be an atheist". It kinda stuck in mind.

"Are we meant to know?"

All indications are God wants us to know enough to have us know all we need to know to live in harmony. The rule “Do unto others” is unsurpassed by human philosophy.
