I just recently completed reading through the book of Hebrews. What a joy!
The primary theme of this book is that Jesus is better than... For example, Christ is better than angels, better than Moses, better than the Mosaic covenant, better than O.T. high priests, better than O.T. sacrifices. He is superior to all things.
I think we would all agree with these things.
Hebrews also implies that Jesus is better than all of our man-made religious conventions and traditions. We, in our attempts to feel good about ourselves, have a tendency to "try to be good," and at times rely on ourselves for "feeling good" about our relationship with God. This is nonsense.
Jesus is better than all man-made ideas about religion. He is infinitely superior to any thoughts, feelings, ideas, or programs we can come up with. His great grace is sufficient for not only salvation but also sanctification.
Let us constantly look unto Jesus, the "author and perfecter of our faith," for all we need. He is superior. He is better than all other things.
Let us avoid any temptations at self-justification. Let us fix our gaze upon Christ and run to Him. He is better.
