What makes you believe your answers and understanding is more correct than other peoples beliefs and answers?
Personally I do not believe my faith or beliefs are the only one that can be correct.
Let me say right off the bat that I do not know for sure that my views are correct. I think they are, but I don't KNOW that they are. There is always a red flag up in the back of my mind that I may be wrong.
Two thoughts.
First, while I'm no genius, I have been blessed with a better than average intelligence. It allows me to learn more facts, weigh their significance, and draw better conclusions than others.
Second, I have done my homework. After my divorce, I felt very lost, and went through a time of searching, where I learned about all the major world religions. I also looked into the various arguments for the existence of God, questioning even my most basic of assumptions. I was seeking, and therefore approached things with an open mind. Where I am at today, as an observant Jew, is a result of that exhaustive study. I don't think there is any substitute for this sort of learning.
