If I'm reading things correctly
If I'm reading things correctly here, Nirvana is saying that the existance of God is provable, whereas others are contending that it is unprovable.
The answer is "Yes" and "No" For whatever reason God has choosen to do so, He has insisted that proof of his literal existance must be proved on an individual basis.
The great crime of organized religion, IMO, is that it has taught mankind that the proof of God can be reached on a collective basis. With the weakening of state religions control over the masses, forward-thinking and reasonable people have "dared" to point out the flaw in this approach. That organized religion may facilitate this proof, it is true but it does not cause it.
I respect the Athiestic position that God cannot be "scientifically" proven, however I, along with Nirvana, assert that the existance of God can be proven on an individual basis AND that the proving of it (and the necessary acting upon any knowledge received) can be done in scientifically rigorous way.
Whether you call it the "Spirit of God" or "Soul Contact" or the host of various names that different beleif systems assign to the giving of this proof, transmitted by God and received individually in a way that removes all doubt (when it has achevied its fullness in you), it doesn't matter. What matters is that it is proof.
Many people in this world confess that they have received this proof. From a statistical viewpoint, there are many hundreds of millions of people worldwide who can look you in the eyes and in full honesty plainly tell you that they have recevied this proof AND that the proof has had a benificial result in their lives.
However, their proof does you not one lick of good. The proof has to be transmitted by God to the "heart" of an individual person. I bring up the statistical arguement only to argue that it is scienfitically indicated that the search for proof may turn up the proof sought after. The formation of a hypothesis, if you will.
Here is a scientific experiment that any honest person may perform that, if God determines that you are "fit" to learn the answer (ie. that you are sincere, and other criteria He may have that I am unaware of) that he will give it you:
Read those things that have been told you are scripture. Contemplate on the meaning of what you read. The amount read is up to you. Think about it over a time and then ask God in prayer if these things are true. You may be able to trick God into telling you that what you are reading is true. A clever scientific mind will comprehend that if they receive a confirmation of the truthfulness of it (in a deeply spiritual way that you will definately know if it happens to you, I can assure you of this) that the transmission of that sensation, feeling, spiritual feeling, whatever, had to originate from somewhere. If you can acheive this level of connectedness with God, its a cake-walk from there.
All you have to do is repeat the experiment with scriptures that talk about God, and when you receive a personal confirmation that what you are reading is true, there's your proof.
Any presentation of the mechanics of how this happens would be fruitless. Get the confirmation first, and then you can start on the path of discovering more about it. Nirvana has talked about "soul contact". La Dee Da. You aren't even at the start of the path yet, you aren't even in Kindergarden yet. Perhaps some of the Athiests are at the school bus stop, but I suspect that most of them are watching TV in the warm comfort of their homes.
No matter what Nirvana or myself or anyone that beleives in the existance of God says to the Athiest makes no difference. The desire to know HAS to be self-initiated. Putting a gun to your head and marching you into the nearest Church won't help, and will put a barrier in your mind of "I hate Church" and perhaps "I hate the idea of a God."
I just wanted to assure you that the techniques of how to get the proof are out there. I can promise you based on personal, scientific experience, that this is the case. It is you that must put one foot in front of the other, figuratively speaking, and seek out that which is waiting to find you.
Nothing more can be done than this, to tell you of the possibility of it.
