Sparky,
If my strength comes from a science that is built upon truth, righteousness and honesty as delivered to us by Jesus Christ then I would suggest that my enthusiasm and belief is all you really need to believe in a teaching that millions have also found great truth in and circular argument has no place in the teaching by 'the light of the world'.
First there's no reason to think you have a "strength".
Second, even if you have (eg, the strength of your opinions, however potty) that "If" is important. It could just as well come from your
belief in these things rather than in their supposed fact.
Third, you're trying an
argumentum ad populum again. Whether one person or one million people have a faith belief says nothing whatever about whether that belief is true, and in any case it leaves you with the problem that millions of people have believed in other gods than your own. Are those gods therefore also all real in your view?
Fourth, the only circular argument here is yours: "the Bible is true because it says it's true; therefore the bible is true; the Bible is true because it says it's true" etc. What you're being asked to do but keep running away from is to break out of that circularity to explain WHY you think this book of all books to be true.
Why the coyness about answering?
