Was there a catalyzing event, person or perhaps a book sealing it in your mind forever the abandoning of the religious faith and "crossing over" into agnosticism or atheism?
With me, I had always had problems with the faith thing but just couldn't exactly figure out what it was. After explaining my predicament, a Miami radio talk show host recommended a book for me to read. I was inclined to trust his recommendation as not only was he an Atheist, raised in the Jewish faith, he was also gay. I immediately went out and bought and read the book. It was a VOILA moment. Like blinders had fallen away from my eyes, I understood what it was that I couldn't put my finger on before.
The book is entitled "FAREWELL TO GOD" by Charles Templeton, a former Canadian evangelist getting his start in association with a young Billy Graham. I'll be forever grateful to the man who recommended this book to me. I highly recommend it to whoever else who is on the fence no knowing what to believe.
