You closed your mind. You stopped wondering and bought into a dogma that allows no deviation from what is taught in church. No thinking needed. When you buy into religion, you turn off the light that says, "if there is no prove that something exists, it is reasonable to doubt any claims put forth for the faith".
Darkness rules your mind.
Khat, I studied the 3 main sciences to 'o'-level, and Physics and Maths (+ English) to 'A'-levels. Whilst I grew up in a Christan family, I didn't become a Christian until just shy of my 18th birthday. For most of my teenage years,, I looked pretty seriously into both Hinduism and Buddhsm and even flirted with atheism. The reason I didn't choose any of them is that - as far as I could seem none of them answered the real questions I had about life and the purpose of ife. In other words, 'when I bought into' Christianity properly, I wasn't turning off a light, I was stating that I believed that these other routes to 'enlightenment' were dead-ends. As I have studied and lived amongst people of yet other belief systems - be that Marxism, Islam, Jainism, materialism or Sikhism (to name but 5) I have found that whilst they may go some way to the light - all of them come up short in some way or another.
I accept that I've probably picked the route that, to me, seems to provide more answers to the questions I've had and will continue to have - but also allows me to have those questions. For me, science, massively important though it is, simply doesn't acknowledge many of the big questions about life; its purpose, its value, its raison d'etre.
