I provided reasons in previous threads why I came to the conclusion, the NT is much more a work of theology, than it is a work of credible history. In my extensive research into the NT, which included reading the works of many NT scholars and historians, many NT historians and scholars have this opinion and when I compare their opinion to the historians and or scholars that will actually claim the NT is all historical, it becomes quite apparent, the one's who claim the NT is reliable from a historical standpoint, are playing fast and loose with the historical method, to protect a belief.
You can believe the NT is completely reliable if you so choose, no one is stopping you.
