Laboring through some of the more difficult passages of Scripture, namely that of Hebrews 6, proves worthwhile as the chapter concludes with a glorious statement of assurance rooted in the finished work of our Lord Jesus Christ. In Hebrews 6:19-20 we read that Jesus is our steadfast anchor, hope, forerunner, and High Priest stringing together pearls of assurance for the believer. Note well the passage below:
“19 We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, 20 where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek.“
The return of the authors use of “we” likely indicates that he is including himself in the statement that follows which highlights Christ’s mediatorial and intercessory work on behalf of believers. In view here, the “this”, is the faithfulness of God to His promises, first as seen in the example of Abraham (Heb. 6:13-18) and secondly, by way of comparison, His promises that are rooted in the finished work of the Son of God. The believer’s salvation and assurance is founded on nothing less than the very character of God and the effectualness of Christ’s death, resurrection, and now intercession as High Priest. In short, a true believer in Christ may fall away to their eternal destruction the moment God can be called a liar and Christ ceases to intercede for them. God is not a liar (Num. 23:19; Titus 1:2) and it necessarily follows that one’s security is eternally sealed in the person of Christ.
This promise is said to be a steadfast anchor of the soul. Again we see the use of nautical language (see Heb. 2) to provide a lasting and understandable mental picture for the immediate audience. By way of the anchor analogy, the promise of God is seen to function as an immovable guarantee. It should not be assumed, as we will see, that the anchor is somehow set weakly or in soft sand that may shift and loosen the anchor. Quite the contrary, the anchor of God’s promise is not only set by God and secured by God, but the anchor is God’s very own Son who gave Himself up for all who have and will believe. Therefore, though the sea may toss and turn, the believer may be assured that the soul of his or her vessel will surely be secured and reach port safely by no merit of their own, but by grace through faith in the Savior Jesus Christ.
Moving on, this hope is said to have entered “into the inner place behind the curtain” bringing to mind the Old Covenant tabernacle/temple where only the High Priest could enter annually on the Day of Atonement. This phrase serves as a notable “hook” to preview and introduce a later developed concept of the superiority of the “tabernacle” in the New Covenant as opposed to the type and shadow of the tabernacle under the Old Covenant. Nevertheless, it functions to support the staggering statement that through Christ’s sacrificial death and ascension to the Father, we now have access to the Holy of Holies and into the very presence of Almighty God. Further, the argument from the anchor, now to the hope that enters, indicates that this is not an abstract statement but has as its object a Person that functions as the anchor and the hope that has entered behind the curtain, namely Jesus Christ. This priestly work of Christ develops the introductory thesis given in Hebrews 1:3 and builds upon the contrast with the Levitical Priesthood in Hebrews 5:1-10 preparing us for the reintroduction of the Melchizedekian Priesthood in the chapter that follows, a type of the superior Priesthood of Christ.
Pressing deeper into the argument we see clearly in the next phrase that it is indeed Jesus Christ who has entered the inner curtain or veil, and has done so as a forerunner or trailblazer on “our behalf”. As though the glory of this passage could not reach a higher crescendo, it is stated with clarity that this priestly work is done with a purpose and object in mind, namely on “our behalf” or for the sake of believers. By stating that Christ has blazed this trail it necessarily implies that there will be followers. As seen in Hebrews 4:16 and upcoming in Hebrews 7:18, 25 the pathway has been opened and cleared for those who draw near to God, not simply one time, but a continual drawing near to God.
Commenting on the use of “forerunner”, yet another nautical reference, Talbot writes,
“The Greek harbors were often cut off from the sea by sandbars, over which the larger ships dared not pass till the full tide came in. Therefore, a lighter vessel, a “forerunner,” took the anchor and dropped it in the harbor. From that moment the ship was safe from the storm, although it had to wait for the tide, before it could enter the harbor…. The entrance of the small
vessel into the harbor, the forerunner carrying the ship’s anchor, was the pledge that the ship would safely enter the harbor when the tide was full. And because Christ, our “forerunner,” has entered heaven itself, having torn asunder everything that separates the redeemed sinner from the very presence of God, He Himself is the Pledge that we, too, shall one day enter the harbor of our souls and the very presence of God, in the New Jerusalem.” 
Using this informative statement, perhaps the significance of Christ as our forerunner takes on a greater meaning by seeing through His work of carrying the cross-shaped anchor into the port of God’s Holy Temple He has eternally secured our safe passage into the harbor. Brothers and sisters there can perhaps be no sweeter truth than to know that we who were once rotten sinners under the wrath of God have now obtained entrance into the Holy of Holies, access to the very presence of God Whom we are told is a consuming fire (Deut. 4:24; Heb. 12:29), through our forerunner Jesus Christ by means of His death, resurrection, and ascension such that we now may come freely to the throne of grace and receive mercy in our time of need. All this we are told is our assurance and hope, grounded in the High Preistly office of our Lord Jesus Christ. Let the majesty of God’s steadfast love through what He has done in His Son on our behalf sink in for a moment and allow it to lead you into meditation and worship of the Most High God.
Hallelujah, what a Savior!
