You have come to … Jesus the mediator of a new covenant,
and to the sprinkled blood that speaks a better word than the blood of Abel.
When thinking of the heavenly priesthood of Jesus, I often focus on the one side of it. I see Him as my representative before the Father, guaranteeing answered prayers and my access into the Presence of God. He does that all right but there is so much more. He not only guarantees that God will answer His part, He also guarantees that I will answer my part. How does He do that? As a mediator He has sent the amazing promise of the covenant, the precious Holy Spirit. He has come to live inside of us to live this life in us. I could never have lived the life the covenant demands of me, but Christ in me, through the person of the Holy Spirit, does exactly that. Here is how Andrew Murray describes this aspect of Christ’s heavenly work.
“A mediator is responsible for both parties fulfilling the obligations of a covenant. Jesus is our surety that God will fulfill His promises; He is also the surety that we, on our part, will faithfully do what God requires of us. Jesus will enable us to fulfill the terms of the Covenant.
It was as Mediator, on the night of the Last Supper, that Jesus gave His disciples the great promise of the New Covenant: the gift of the Holy Spirit, foretold earlier by Ezekiel.
He also undertook to fulfill the promise, “I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws” (Ezekiel 36:27). It was in fulfillment of this promise that He told His disciples, “I will ask the Father, and he will give you another Counselor to be with you forever”.”
What an amazing benefit we have with Jesus as our High Priest. He represents us as a man before His Father in heaven. He represents the Father as the Son of God to us. Son of Man and Son of God, this is the great mystery of our salvation. Jesus is the guarantee that these promises on both sides will be fulfilled. We can come with boldness before the throne of grace and find help in our time of need because as far as the Father is concerned it is the very Son of God making the requests.
