The "story" of the New Testament can be summed up, but that doesn't do it justice. The New Testament is something that should be read for yourself. Cliff notes are great, if all you need is a shallow understanding of the book, but the scriptures deserve more than that. If you really want to know the story of the New Testament, I honestly desire that you read through it, and prayerfully consider it. It has changed many lives, but not usually second hand.
For me the story is the same as the Old Testament - centering around Jesus Christ. His grace and mercy. Of course many side stories that surround the main focus are important lessons for us, his children.
