The first thing we need to learn for us to properly understand the book of Hebrews is that this is not a letter. There is no author listed, no recipients named, no salutation extended, no thanksgiving given, or any other markings at the beginning of this writing to suggest that this is a letter. The end of the book has a few marks that look like a letter but those exist because this was going to be circulated through the churches and Christians. But this ending section is what tells us that this is not a letter, but a sermon.
Brothers, I urge you to receive this word of exhortation, for I have written to you in few words. (Hebrews 13:22; HCSB) The form of this book reflects a brilliant, well-crafted sermon.
So what is this sermon about? I have always seen that this is a book about the superiority of Christ. I believe I was wrong. The theme of the book is to not give up. The words of exhortation to not give up are often perceived to be side points for the key theme about the superiority of Christ. But I believe the point is to not give up. The superiority of Christ is the basis of the argument to not give up.
