I lived a Christian life for 30 years. I feel that I missed out because of it. Sure, there are experiences that were special and spiritual, but at the same time, other things didn't fit in. You get something but lose something else, whichever side you're on.
not to get too personal, but i was raised a christian prude, it wasnt til i was 18 that i started questioning my beliefs, and by the time i was through praying to god for guidance, talking to several pastors, deacons, sunday school teachers, fellow brothers and sisters in christ, my family etc, reading the bible, several christian and atheist books on the issue, and finally making up my mind, i was 22... by that time the damage had already been done. here i was an atheist prude having lost the best years of my life, not having had fun or experimented with anything....sex, drugs, gambling, parties, flirting, chasing tail at the club nothing...... but the real damage had only started, because at that point i only had christian friends, no members of other religions and certainly not those evil rebellious atheists i have been taught to stay away from.....well, to make matters worse, my doubts and questions slowly alienated a good chunk of my christian friends, and by the time i finally came out as a non believer, i had but 2 christian friends/friends at all.. remaining, who were really secular/in name only christians..... so here i was at 24 years old, robbed of my youth, unable to make new friends because my prude christian personality had already been shaped, a lone wolf with no social support system...i couldnt fit into christian or secular society....which naturally lead to further withdrawal and depression.....it took years and years to undo some of the damage, but plenty remains and can never be undone. talk about missing out on all the fun
