Fingerprint - Yes I was an atheist. Although christened and married in a C of E church, I really didn't believe, never gave it much thought, and although made to go to church as a kid, I thought it was boring and hogwash.
Then me and the missus went to the pictures to see the Exorcist, (about 1978), and at the end there was a bible quote on the screen about the mark of the beast, 666.
I spoke about it in work, didn't know the meaning, and a born again Christian, (I didn't know he was until then), explained it, then went on to explain the whole concept of Christianity, how Jesus died for our sin to satisfy Gods' perfect justice.
It made sense to me, and the rest is history. (I was 29 then). I didn't become a Christian in a flash, for me it was much more gradual.
I'm off to work in a minute, so not much time to write much more.
