I don't know. There are times when I really do think ignorance is bliss. If I could just accept things as others describe them life would be much easier.
In general, I think thousands of years of religious dogma have essentially put up barriers between us and "god."
Many of us (although few of us here on the forums) don't even try to define what "god" is. We look at a guy with a bushy white beard, a specific physical manifestation of spirits, etc. Why? Because our religions say so! We have preachers, holy texts, and renaissance paintings to show us and tell us what god is. Many of us are NOT outside of the box thinkers. We are lazy. It is so much easier to just embrace other people's ideals than to come up with our own, let alone the social implications of casting everything else aside.
But what we fail to realize is that if a higher power does exist, then he/she/it is something that we obviously have not experienced. We have no point of reference. If physics cant lead us to god, then surely even our own imagination can not.
In conclusion, I think questioning a religion is something that can actually strengthen your faith, not weaken it. Any religious person should be able to understand this. If they can not, then they simply are not adhering to religion for the right reasons...
