We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek.
> Hebrews 6:19-20
The hope we believers have from God is secured and rooted in Jesus’ work on our behalf, both in His life in living sinlessly before the Father, as well as His work on the cross to deliver us from the wrath of God, in order that we may be reconciled to Him and gain God as our treasure. And more specifically in this passage we see the work of Jesus as our faithful High Priest who forever lives to intercede on behalf of those who have faith in Him. Before Christ came and instituted the new covenant by His blood, there was an old system God setup, by which each year, the High Priest would enter the most holy place of the temple through the shedding of blood in order to atone for the sins of the people. This was a very specialized practice where if one thing was done wrong, the High Priest would die instantly. And this illustrates one thing amongest many things: God is holy and just and He takes His glory seriously, so seriously that people would die if they did what He told them not to do in the temple as well as with the ark. And this system was setup to typify that which would occur later, that Christ Himself would be the greatest and final High Priest on behalf of those who possess faith in His blood. He came in order to be not only that High Priest who intercedes for His people, but also to be the very sacrifice Himself offered on the altar to remove sins, blotting them out forever. And the hope we have, this anchor of the soul, enters “behind the curtain,” or into the place where God Himself dwelled amongest the Israelites. That is our hope! We get God for all eternity! This is the best part of salvation. The mighty majestic pillar of fire that appeared to the Israelites is now the one who dwells in us and we ourselves have become sancutaries of the most high God, slowly but surely being conformed to the image of Christ by His work. And all this thanks to the work of Christ to absorb God’s wrath in Himself on the cross, to take on and experience hell itself so that we don’t have to, and give us the very righteousness and perfection we need to stand before God at the judgment of all men. And instead of getting hell, we get the very Spirit of God Himself, the one behind the curtain in the old system, that now dwells in our hearts. How wonderful and amazing is this, that God can indwell sinners! And it could only have happened through the death and resurrection of the Son of God. As it recently said on the DesiringGod.org website (my paraphrase), “Christ did not so much die as an example to follow, but as a sacrifice to actually pay for sins.”
