Scripture: Hebrews 1
The book of Hebrews is amazing. Commentator Matthew Henry declared that "if we compare all the epistles of the New Testament, we shall not find any of them more replenished with divine, heavenly matter than this to the Hebrews." Adam Clarke asserted that it "is by far the most important and useful of all the apostolic writings... so many are the beauties, so great the excellency, so instructive the matter, so pleasing the manner, and so exceedingly interesting the whole..."
I've always loved Hebrews, so I have no argument. Though Clarke's Apostolic Writings Power Rankings were pretty forward-thinking in the late 1700s. I imagine he posted them on his Irish town's local Buzzfeed Stone Wall.
