The great object of the apostle in this portion of the epistle is to develop the blessed character of the priesthood of Christ. Having referred to the Melchisedec priesthood to show by analogy the dignity of the priesthood of Christ, the apostle breaks off the thread of his discourse to resume it again at the beginning of chapter 7.
In these parenthetical verses the apostle refers to the spiritual state of those to whom he is writing. Their dull condition of soul exposed them to a serious difficulty and a grave danger. The difficulty was that they were unable to interpret the Old Testament figures. This is referred to from chapter 5:11 to 6:1-3. The danger was that in their low condition some might give up the profession of Christianity and turn back to Judaism. This danger is developed in chapter 6:4-8. The remaining verses of the parenthesis express the apostle’s confidence and hope concerning those to whom he is writing (Heb. 6:9-209But, beloved, we are persuaded better things of you, and things that accompany salvation, though we thus speak. 10For God is not unrighteous to forget your work and labor of love, which ye have showed toward his name, in that ye have ministered to the saints, and do minister. 11And we desire that every one of you do show the same diligence to the full assurance of hope unto the end: 12That ye be not slothful, but followers of them who through faith and patience inherit the promises. 13For when God made promise to Abraham, because he could swear by no greater, he sware by himself, 14Saying, Surely blessing I will bless thee, and multiplying I will multiply thee. 15And so, after he had patiently endured, he obtained the promise. 16For men verily swear by the greater: and an oath for confirmation is to them an end of all strife. 17Wherein God, willing more abundantly to show unto the heirs of promise the immutability of his counsel, confirmed it by an oath: 18That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us: 19Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil; 20Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec. (Hebrews 6:9‑20)).
