How does one....

"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."

....believeth in Jesus?

If this is true..... Then apparently nobody has yet done that as everyone dies. Or there is no recored of anyone still alive beyond their normal human lifespan. Even Jesus is no where to be found. Oh yeah, we can't have proof, cause there simply is none, or you are just suppose to believe.

Perhaps we need a full and complete list of qualification as to what is needed to satisfy the requirements of "believeth". But we are all in part, so who is qualified to say what the qualifications are? Not to forget that being in part you will never completely qualify.
Catch 22 built into the philosophy.

Do you believe he lived?
Do you believe he was born of a virgin?
Do you believe he was a teacher?
Do you believe he performed miracles?
Do you believe he died and came back to life?
Do you believe he was innocent?
Do you believe he was wrongly murdered?
etc...
..and the list can go on and on.

and all these things are possible, or so they may appear to be.
We even have evidence of life that changes sex as needed and not to forget even life that generates sex organs when needed and self reproducing life. And we certainly know enough about DNA that we can, even if only in theory at this point, create human life capable of such self reproduction.

I recall seeing a story on how Religious scholars from many different beliefs got together and researched the documentation, which is about all that is existing in evidence of the stories.
What they came to discover was not what is generally taught or believed. They found many of the books of the new testament were simply rewrites of the book of John, but with another bias towards a particular peoples.

Hmmm, and so god so loved the world that god did what?
God gave us bad or incomplete instruction?
Forgive them father, for they know not what they do.
But we got the knowledge of go forth and multiply, just fine.
If Jesus could see that, and god is all knowing.... what is missing in this picture?

Everyone wants success, love, etc., so why is it not happening?
People take action based upon what they know and experience. Does god not know this?
There is a difference betwen knowing and believing. You can say you believe what you know, but you cannot always "know" what you believe. Forgive them father, for they know not what they do.
But if you believeth......

And if Jesus was brought back to life "father why have you forsaken me?" apparently Jesus didn't know then either, so what is all the fuss really about? if christ is alive, no harm was really done and obviously any lesson of not committing murder .... hasn't worked so well as neither did the great flood really teach or filter the bad out of mankind much.

If god is busy trying to filter the bad out, why is god trying instead of doing it?
Even we have been able to selectively bread foxes and turn them into domestic pets in a period of only 30 years.

One thing is for certain, the religious beliefs do tend to help some believe they can blow themselves up and hurt others. And somehow live on. it all seems to be a self supported dependency of the self destructive. Die so you can live, just believe.

IS there any proof that god said such a thing as "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."?

Of course not! Or maybe thats a "should" that simply doesn't.

Just believe.... if you can figure out how to satisfy the believeth terms.

The why of this post is simply because I have grown tired of those who, even in their own self professed sinning, somehow manage to make a judgement on me as to whether or not I believe.
However, I ultimately realize that what they really want is for me to submit to their self serving philosophy. I realize they really don't believe, except in their own deceptions and their ability to convince themselves otherwise.

What better mask for evil to put on than to subtlely mislead by the presentation of being something good while introducing distortions that equate to less than good?
