The whole letter of Hebrews is focused on the New Covenant in contrast to the Old. Many of us recall how Chapter 11 reviews the host of faithful from the Old who are now watching us from Heaven. The New Covenant is everything they were hoping to see as they played their role in bringing conditions to the place where the Messiah would come. The thing that kept them on the path was their faith — their commitment and submission to God. They believed His promises.
Thus, in Chapter 12 they stand as witnesses in both senses: (1) They testify that God is faithful to those of faith and (2) now they are spectators to our struggles. We are the continuation of their great works of faith. This chapter calls on us to sacrifice things we cannot keep in the first place, to join them in dismissing the cares of this world and of our fleshly natures.
Thus, “every weight of sin” refers to that baggage of fleshly concerns. Nail it to the Cross and stop worrying about it. Otherwise, we will be like those fat kids who can’t run very far. We need to drop those cares or be forced to drop out. Real athletes sacrifice a lot of common concerns to focus on one thing. The goal is to emulate Jesus in our own lives. He was like a true athlete, able by faith to carry His Cross and finish the course. His prize is that He now sits at the right hand of God.
Opposition from the world? Jesus knows all about that. His own family gave Him grief all the time because they never believed He was the Messiah until after His resurrection. His nation rejected His claims, too, and called Him a blasphemer deserving of death. The writer of Hebrews warns his readers that they haven’t faced that level of testing yet.
The Devil is going to keep trying to push fleshly concerns back into your awareness. He wants to drag you down with a load of false care. The Devil profits from our failure to join the cloud of witnesses to covenant faithfulness. He wants desperately for the Elect to screw up, to fall short of the Cross. If necessary, we should be ready to shed blood our own blood.
Then the passage quotes from Proverbs 3:11-12. The point here is that God has already abandoned the rest of the world to the Devil. They don’t get His attention and discipline. However, His Elect are His family, and they get His direct attention. We who embrace the Covenant face a level of discipline — testing and trials — that the rest of the world never sees. It is a mark of His love that He pokes and prods us away from the cares of the flesh. The Lord wants us to stop serving the Devil and to embrace the glories of His Covenant. The sinners never get that kind of love.
Yep, this is going to hurt, folks. But your flesh is not the real you. It’s going to cry out in misery, but you must not surrender. Don’t let the weariness claim you and keep you away from the privileges of the Covenant.
Those blessings include being able to keep peace with the most unlovable people. It means keeping holiness in a defiled world. Keep an eye on each other so that bitterness doesn’t creep into the covenant community. Take a warning from Esau, who lived like the animal he was, caring only for the comforts of the flesh.
We aren’t facing the frightening covenant handed down from a stormy mountain in the desert. We don’t have to line up animals to burn on an altar just so God won’t hand us over to the Devil. Our Promised Land is our own lives redeemed from the power and deception of sin. Our future home is not just some turf on this earth, but an eternal paradise in Heaven. It cannot be take away from us. The blood has been shed once and for all on the Cross. All we have to do is claim the power that comes from it.
This covenant did not come from angels, but from the Son of God Himself. How can we ignore what He demands of us? It’s not a thousand fussy details and rituals, but the simple law of loving as He loves. This world can offer nothing so wonderful.
