Thankfully, there are people like NT Wright and his monumental 6 part series :Christian Origins and the Question of God. This would take a lifetime of constant study to get through, probably. He is one of the best theologians we have in our time and he provides a solid defense of Christianity as far as I can tell. I just obtained his books and I am committed to the massive task of reading them. They are very dense, but, nonetheless, the amount of information here is extremely exciting.
