OP, only a little over a month ago, I was, as astray, as you are now. Also raised in faith and abandoned it in my youth because I thought I knew it all. In my obsession for rational reasons and thoughts for everything, I second-guessed (almost) everything and deconstructed myself as well as perception further and further. Ironically, I found reasons to believe again through JewTube, 8chins and, most importantly, through the realization that I wasted my most important years of development with denying the truth that was - and still is, yet flawed - ingrained in my character and was also layed in front of me [that is The Bible].
See it that way: The Bible is a historical documentation from the creation of Earth until the mission of the apostles, including a revelation of the end times. Biblical history complements perfectly secular history, as well as its predictions of the modern era. Giving my guess, you abandoned your faith because your knowledge and thoughts have been poisoned through Talmudic indoctrination, which rewrote history a great deal, hence nobody shall blame you. Now, you have the offer to either accept or reject the truth, if you have read this far. In embed related you'll find a video that summarizes historical events with The Bible and secular history books, and our and the world's relation to the descendents of Abraham and the Jews. Either watch it or research on your own to get rational arguments for The Bible, for Christianity, or dwell in ignorance.
