Great post by the SpongeGodol SquarePants Hador about why he believes and what doubting Jews can do. I can't recommend the rest of the blog but this post alone is excellent. Not that I necessarily agree with everything in it, but I can recommend reading it.
I'll also commend him for taking a cue from the Meharher and using a bold outline in a long post. Here's his outline:
1. Must a Jew Believe Anything?
2. Faith and Doubt
3. Value
4. Proofs
Prophecies in the Torah
Success of the Basic Ideology
Other Religions
Unique History
5. Study
Conclusion
