I have, a couple times from front to back, literally. Some before becoming a "born again christian" some during. Looking back upon how i acted and my "beliefs" during that time I can honestly say I was delusional. I was so scared and lonely I was grasping to anything to allow me to connect to other humans. I lied to myself so strongly that I believed every day events were god's guiding hand "helping his flock", personally blessing me for becoming a christian. It was like a drug, a self induced euphoria. In the end I took to the teachings of Jesus so strongly that it ultimately ended my faith. I held them in my heart, looked out into the world and despaired because I could find no other Christians, all their beliefs were twisted, contorted and contrived for their own good instead of being rooted in the words and spirit of Jesus. Take care of the sick, the elderly, the poor, love one another as brothers, welcome strangers, outreach to those you find abhorrent to help them with unconditional love, cast off pursuit of worldly wealth and possessions to help your fellow man, all of these I found to be the basic tenements of Jesus's teachings, and all Christians I knew, all that I could see, lacked these basic qualities.
