15 And the Holy Spirit also bears witness to us; for after saying,
16 “This is the covenant that I will make with them
after those days, declares the Lord:
I will put my laws on their hearts,
and write them on their minds,”
17 then he adds,
“I will remember their sins and their lawless deeds no more.”
18 Where there is forgiveness of these, there is no longer any offering for sin.
19 Therefore, brothers,[a] since we have confidence to enter the holy places by the blood of Jesus, 20 by the new and living way that he opened for us through the curtain, that is, through his flesh, 21 and since we have a great priest over the house of God, 22 let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. 23 Let us hold fast the confession of our hope without wavering, for he who promised is faithful. 24 And let us consider how to stir up one another to love and good works, 25 not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.
First, this goes to the ultimate value of the sacrifice of Christ as communicated by the New Testament or New Covenant. The stain of sin is removed by the giving of Christ’s life, and that gift is received by our response of obedience. This is when God says, “I don’t remember what you did.” In the language of the Holy Spirit: Your sins and iniquities I will remember no more.
At verse 19, there is a big THEREFORE, and that signals to us that concluding exhortations are coming. These are framed through the imperative, “Let us.” Let us draw near, let us hold fast, let us consider one another, let us not neglect the assemblies. When we open our hearts to the New Covenant, God puts these truths into our hearts. We live by them, we are encouraged, we hold fast to the hope – believing that He who promised is faithful.
