Verses 1-4, The writer is pointing back to the truth that the O.T. sacrifices were shadows of what the sacrifice of Christ would one day provide for those that worship Him. As opposed to those who offered bulls and goats that could never deal with sin or cleanse their conscience. See Ps. 51:16-17
Verses 5-10, The writer now quotes from Psalm 40 to show that Christ’s sacrifice was greater than the O.T. sacrifices because His was a willing sacrifice. See Ex. 21:5-6; Mt. 26:36-44.
Christ offered His body as a sacrifice, becoming the perfect intersection of the heavenly and earthly, deity and man, sinners and saints.
Verses 11-14, The O.T. priests never finished working, but Christ is seen as seated, finished, and triumphantly applying His finished work as our High Priest until He returns as King of Kings!
Verses 15-18, Here the writer refers back to the quote of Jer. 31:31-34 and shows that Christ’s work has procured for us redemption from sin once and for all. Only His sacrifice could cause us to no longer need a sacrifice.
Verse 19, therefore encompasses all the arguments that the writer has presented since chapter 7. Since all of that–we can be bold as to the manner and pathway into God’s presence.
There is now no need to try and get God “on our side” because God has shown us through His Son that He wants us! We are to push into God’s presence and live out our whole lives there!
Verse 20, How do we know this? Have this access? By a new and living way. That which was previously inaccessible has been made open by this new way. The veil was the point of entry into God’s divine presence. That point is Jesus’ bodily sacrifice for us! There is still only one way, but it is now open. John 14:6!
Verses 21-22, So let us draw near, proving our confidence in the work of our heavenly High Priest. The language of sprinkling and washing may be picturing us as priests moving into the presence of God. See Ex. 29:4; 30:22-30; 1 Peter 2:5; Rev. 1:6.
Verse 23, The writer encourages and exhorts these believers to hold onto what they already believe of Jesus–4:14–and not to back down or give up.
Verse 24, How do we practically do this? By cultivating love and good works in our own lives, and then sharing them with others. By doing so we are loving the body. See. Rom 12:1-5; 1 Cor. 12; Eph. 4
Verse 25, This is not just speaking about missing a Sunday or Wed. night service. This is the person who is willingly making the concious decision to do without the community of worshipers gathering around Jesus Christ to come to God.
