And why I can say that with such conviction is the more I learn, look and contemplate in the Torah, the more I see logical proofs that it is the truth
That was a mistake on my part. I believe the Torah is divine even if I would not see any logical proofs of that.
What I meant to write is that I believe that Torah is divine AND the more I learn, contemplate and analyze, the more I find logical proofs of the Torah’s divinity.
Since every Jewish soul was at Har Sinai, in each of us there is an intrinsic belief that the Torah is divine, but sometimes because of vairous reasons some of us may not be conscious of that fact.
