Simple inquiry of those who don't believe God. If God made His existence abundantly obvious for all to see and His existence was irrefutable, why would anyone need the most critical component to understanding His will, faith?
Why is faith a critical component? Why not obedience and actually following divine will?
Well ya see faith enables the grand travesty to continue unabated while the other may actually require a god to turn up every so often.
Indeed; what better a tool for controlling people than provide a being who cannot be disproved, and thus only exists from entirely blind faith?
Run it through
Occam's Razor: what's more likely, a mellenia-old means of power-grabbing (let's look at the history of the human race, here), or an infinitely complex "being" that defies logic, reason, and indeed the laws of the universe simply by conveniently being "beside" it?
Feel free to argue that God is none of the above, and I'll happily debate it.
Because you have to have faith and believe.
There is no way around faith and belief in Jesus. :hatsoff:
I know this doesn't occur to believers that this doesn't make any sense logically, as it is their worldview (and therefore it makes all the sense to them). What you've basically said, quite literally, is "you have to have faith, because. There's no way around it." I won't go into detail how there's not actually an arguement there, but suffice to say there isn't.
So indeed, why is faith necessary? Hell, why would obedience to divine will be necessary? If we are subscribing to an omnipotent, omniscient* "being", what does it matter what we do? God would have, after all, power over our every action (free will doesn't really exist even from a biological standpoint, nevermind a metaphysical sense), or even if free will was applied, God set all the starting conditions. That's kind of (actually, pretty much the same) like having a pet rat, putting some food in front of it, and punishing or rewarding it for eating the food. It makes the same sort of sense.
To move on a bit, my favorite argument for the existence of God was put forth by none other than Sigmund Freud, in
The Future of an Illusion (note: he's not arguing that God exists, but that mankind created God to meet its needs).
* Here's something to chew on: how does an omnipotent, omniscient God change its mind?
