What is the most important element of the NT?

The opening line of his preface to Romans, Martin Luther identified the book of Romans as "This letter is truly the most important piece in the New Testament. It is purest Gospel."

Whelp, I really thought the Gospel was "truly the most important piece of the New Testament." I thought the Gospel was the "purest Gospel."

I know that I am not a Martin Luther. I know that I also have not read the entire preface Luther wrote. I know that I am not the most clear theologian. I know that I may not be giving Luther a fair shake on this.

But what I do know is nothing in the Bible is more pure Gospel than the actual Gospels.

Nothing in the Bible is more Jesus than Jesus.

Nothing in the New Testament is more important than Jesus.

All due respect to Luther, but I think he and I may have a difference of opinion of what the "Gospel" is.
