What Christian ideas are found in the New Testament that are not found in the Old Testament?

## Background Inspired by https://christianity.stackexchange.com/questions/29919/what-important-mormon-doctrines-are-taught-in-the-book-of-mormon-that-we-couldn The Hebrew bible contains history , religious laws , sensual poetry , creation stories, and more. But scholars have long noted a lack of systematic theology compared with other religious books (not that there isn't theology contained in the Hebrew bible). On the other hand, authors of the New Testament make extensive and explicit theological arguments, a clear example is *Epistle to the Hebrews* which marked the line in the theological sand between proto-Christianity and 1st/2nd Century Judaism. ## Question What are doctrines or ideas, small or large, which are only found in the New Testament? I am interested in all perspectives on doctrines, theology, etc that are 'new' in the New Testament. This question will require an amount of good faith from any answerers, since a *post-hoc* reading of the Hebrew bible ***could*** gin up support for any number of NT innovations. I'm looking for ideas that are clear in the NT but unclear or not found in the Hebrew bible. ## Example answer An example could be: >> For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it *James 2:10* > The idea that breaking any one of the commandments is equivalent to breaking all of them is not found in the Hebrew bible and appears to be a new doctrine found only in the New Testament
