Jason Lisle: Creationism exists, but atheism doesn't

[Esquilax]

Claiming to have "no need to even prove it," is different than claiming "I won't prove it."  If you read carefully he, standing upon the truth of Romans 1, says "All I have to do is expose his suppressed knowledge of God." 

The issue is that he's got a lot more to do to expose that than just quoting Romans, and he doesn't, you know, do that. His position begins and ends, literally, with "the bible says."

Scriptural evidence for this claim is....

No such thing as "scriptural evidence," where the scripture also constitutes the claim.

On the one hand I agree with you.  It does seem that more and more Christian's are unable to properly submit to 1 Peter 3:15.  Because while the Bible is truth, quoting it doesn't necessarily provide our reason.

Quoting it won't provide your reason ever; the bible is the content of your beliefs, not the reason you believe it, except of course if you're presenting additional facts from the outside world to verify what's there. Quoting the bible alone will never be sufficient, and it's all that Lisle does here.

On the other hand that fact does not necessarily negate the truth of the Bible, nor would it necessitate that somehow God endorses a lack of understanding.

I never said it did. It's merely an indictment of the shallow thinking and aggression inherent in certain christian sects.

I would add that a 'lack of caring if it's true' would be a specific example of suppressing the truth in unrighteousness.

Why would you go there? Why indulge in the same passive aggressive well poisoning that's been a part of your religion since its inception? Why be so dishonest?

It is true that the conclusions we draw are filtered through our worldview.  That being said, if our worldview is flawed or even self-refuting, we wouldn't be able to trust any conclusions that we make.    

Better not just quote some old book as justification for your worldview then, eh?
