>If you had not been born in a Christian or Western nation, do you have confidence you would have still found the Lord?
Yes. But then again I'm not answering the question correctly. I was found by Him, not vice versa.
>Did you choose your denomination based on actual doctrine and belief, or just the aesthetics?
I didn't choose it. I was guided to it.
Also, speaking as a 21st Century European citizen, Christianity and living a properly Christian life are almost completely removed from the minds of most people, so much so that many who even call themselves Christian just sleepwalk through their devotions (even most of those who devoutly attend weekly mass), while simultaneously and openly espousing modernist, worldly heresies or abominations. It was the edifice of Europe but in so many places it is now just the sediment.
This isn't the same cultural or religious climate that our grandparents or even parents grew up in, so this "Gotcha!" type question doesn't even apply.
As far as many of us converts and reverts are concerned, we may as well have been raised in outer Mongolia.
