Is god just? How do we know if he is?

Who wrote the bible then? God? I can write anything that says, "I am just."

You can't just prove yourself to be just by merely saying so.

If you believe what the bible says, God does not necessarily have to be just. You could, in fact, be following an unjust god.

And where is the link between faith and reality?

I never asked for proof. I asked for a link between faith and reality.

There's no link then? We cannot be so assured? Faith does not equate to your view of reality?

God is in the realm of the supernatural. How little you know of the world?
Suppose everything God said was right. How can you be sure of that? There is a chance probability that you are right, but more of a chance that you are wrong than right. If god was all good and all just, then the tree in your backyard contains the spirit of Napoleon.

How do you know that there is not an invisible, silent and completely undetectable fairy sitting on your head knitting you invisible socks?

In case anyone here is atheist, let's say that there is a diety. It matters not their quantity, except that it is greater than zero.

We rely on this diety for knowing what is absolutely just.

But how do we know that this diety is just? Are we simply bowing down as slaves to those more physically powerful than us or are we really relying on this diety for what is absolutely just?

Let's consider Christianity. How can it be just if it shows contempt against women, or homosexuals, for example? Is that just?

If God wasn't just, how would you know what absolute justice is?

Since you do know what justice means, it also means that God is ABSOLUTELY JUST!

And if you raise those questions about Christianity then how about this?

Why does Islam say one thing but muslims do another. Shouldn't we say that Islam, the religion that guides muslims is the biggest delusion because it fails to guide them?
