The New Testament
The New Testament is rich in honesty, exploring, transformation and Holy Spirit adventures. As the BibleProject explain: "The New Testament is not a whole "new" story, but a continuation of the entire Bible so far. The Old Testament, also known as the Hebrew Bible, tells an incomplete story about God and Israel and their continual failings to be the people God calls them to be but also gives us hope of a coming Messiah. The New Testament tells the story of that long awaited Messiah, Jesus." The New Testament contains 27 books, which were all written within roughly 40 years by Jesus' followers.
The word 'gospel' comes from the Greek word euangelion, which simply means 'good news'. It was most often used referring to a royal announcement of a king, so when Jesus' followers proclaim the gosple, they are announcing the Jesus is King
