Lately I've come across a few deconversion testimonials that describe the process as initated by awakening sexual awareness--to distill it down a bit. For me, sex had nothing to do with it, although the feeling of betrayal is one to which I can relate.
I do feel that God, if you believe in him, set us up to fail, but not in the areas of purity and/or holiness. My #fail categories are 1) independence, and 2) intellect.
Let's deal with the first one first (I discussed this a bit in this post). I am independent; I like living life on my own terms--in fact, I have an innate need to do so. I am unhappy bending my will to that of anyone else; this is why I am averse to relationships and never made student leader in my college marching band.
I was raised to believe that Christianity was a joyous alternative to secular living; if the "real world" fails you, turn to Jesus, and he will show you a better way! Don't like the materialism of our culture? Christianity will teach you to live humbly and sparely. Kids on the playground teasing you? Jesus loves you no matter what. Disagree with the laws of your society? Religion will give you higher laws to follow.
Well. This is not the case for my relationship aversion. Societal pressure to partner up is immense; the underlying attitude is that a person is not complete unless and until they are sharing their life with another person--and just one person. You might think you're happy alone, but you'll be much happier once you get yourself into this very specific attachment that society has so handily outlined for you.
I don't like it. I don't like the idea that I'm not a whole person by myself, that I need someone else in order to be truly happy, that despite entering this world as an individual, I am somehow missing a piece of my puzzle and will not be satisfied in life unless I die involved in a long-term, serious, romantic relationship with just one other person.
What's that? I don't like secular society? Turn to Jesus!
Oh, wait. He's saying the same goddamn thing, except replace "romantic partner" with "Jesus Christ".
And so God created me, supposedly, to be the independent, fiery creature that I am, and expects me to sacrifice my innate personality in order to be a good follower. He expects me to accept that I'm not sufficient on my own, that I need him. He expects me to do his will, and to pray to him asking him to make my will his will. He expects me to sacrifice the very core of my being, which he supposedly created.
I will not submit.
And that is what Lucifer said, supposedly, at the beginning of time when he exercised his free will and chose not to follow God. Of course, since I couldn't find those specific words in the Bible (my mom always quotes me the above version), I can't be sure, but he definitely said "I will ascend to Heaven, above the stars of God I will set my throne on high; I will make myself like the Most-High" (Isaiah 14:13-14). The guys who wrote the Bible were totally there.
