The so-called Blasphemy Challenge website is addressed quite succinctly in the video below. I learned about this clear and simple reply via Challenge Blasphemy, a direct reply to the "Rational Responders" site featuring videos of people declaring their faith. My story is posted there, but I don't have a video up because I don't have my webcam with me at the moment. For now, check this out:

DISCLAIMER: I do not endorse all of the biblical interpretations proposed Mr. Inns' website.

The "Blasphemy Challenge" is an example of what I'll choose to deem, somewhat obtusely, "know-nothing know-it-allism". (Obscure Simpsons reference.) For a better discussion on what it really means to "blaspheme the Holy Spirit", see Holding's The "Unforgivable Sin" — and Who Can Be Forgiven.

For Christians, I encourage you to record your own video explaining the reasons why you believe to submit to the Challenge Blasphemy website. For those who aren't, please consider my story of why I now believe (when I certainly didn't before) and those of others who explain why they now believe.
