I have a very good reason not to trust what Christians offer - they are humans.
And you think Christians are on par with the Nigerian lottery winner or the slippery insurance salesman? Why is that? It sounds also like you're suggesting lying is a default human setting. If so, how far does this view extend? Does it include yourself?
And I believe that the bible itself labels us as sinners.
Well, even sinners are capable of communicating truth. Is the sinner who says 2+2=4 telling a lie? Is it a lie when Joe the sinner gets awakened from a dead sleep in the middle of the night and he tells you that he's annoyed that he's been awakened? When little Bobby the sinner pulls a fish out of the water with his fishing pole and he exclaims, "I've caught a fish!" is he declaring a falsehood?
To me that is very good grounds, not necessarily to reject it, but certainly to say - come on guys I need a bit more than your personal assurance.
You doubt the Bible when it says we are all sinners? Really? Have you never uttered a falsehood? Have you never stolen anything? Have you never hated anyone or looked upon another person with lust? If you have, then, as far as the God revealed in the Bible is concerned, you're a sinner.
Maybe, though, you don't believe that the evil men do is actually evil. Is this where you're coming from?
Not at all. I am totally convinced that a sharp knife will cut my skin, I have the scars to prove it.
But another person may come along and say, "I don't believe it. I don't believe that scar is from cutting yourself with a knife. You're a human just like those rotten Nigerian con artists, or lousy insurance salesman!"
Judges are totally convinced every day of criminal actions and send people to prison.
But the mother of a convicted criminal may refuse to believe her son is as bad as the court has determined he is, no matter the evidence against him. Sometimes, people have a deep bias that bars them from acknowledging the truth.
Indeed our individual requirements may differ and some may require more evidence than others, but surely God can cater for that?
Why should He? Why should He have to jump through every individual's hoops of proof? He's God: We jump through His hoops. Though this is true, He
has provided sufficient reason to believe. It may not be all that everyone wants, but it
is sufficient.
Which objective standards do you suggest I use?
Well, how about those used by philosophers, scientists, and courts of law?
A body of evidence that is unconvincing to the majority of humans may be irrelevant as to whether it is true or not, but if it is true the evidence needs to be improved so that this is no longer the case.
There is more at play in convincing people of the truth than just the quality of the evidence that it is true. The Bible indicates, for instance, that people reject the truth of God revealed in the Bible, not because it's poorly supported, but because the truth condemns them. For many, it is more important not to feel condemned and not to have to admit fault than to acknowledge the truth. How often I've seen people refuse to admit they are in the wrong when it is obvious they are! Other people reject the truth, not because the evidence for it is insufficient, but because the truth is inconvenient or interferes with their self-gratification. This is the case for the drug addict, or alcoholic, or addicted smoker. There is, then, often more to why people deny the truth than the absence of better evidence for it.
As it stands we have around 4 of the 12 jury members on the Christian side. Something needs to be done.
What jury is that, exactly?
God is doing just what He wishes to no matter the skepticism people have toward Him. He's not diminished in the least by the unwillingness of people to acknowledge Him and live in obedience to Him. His reaching down to us and offering us fellowship with Himself is an entirely one-sided thing: All the benefit is on our side, not His. He doesn't need us a bit; but we desperately need Him - though many admit this far too late.
