The writer proceeded to explain the superiority of the New Covenant by comparing it with the Old Covenant using the figure of two mountains: Sinai and Zion.
12:18-21 These verses describe the giving of the Old Covenant at Mt. Sinai (cf. 2:2-4; Exod. 19:9-23; Deut. 4:11; 9:8-19).420The writer made Sinai and Zion metaphors to show the difference in quality between relationship to God under the Old and New Covenants (cf. Gal. 4:24-26).421The emphasis in this comparison is on the holiness of God and the fearful consequences of incurring His displeasure (cf. Judg. 13:20; 1 Kings 8:12; 18:38; Nah. 1:3; Matt. 24:31; 1 Cor. 15:52; 1 Thess. 4:16). God was far from the Israelites, and even Moses felt terror.
12:22-24 The giving of the New Covenant and the things associated with that covenant are more impressive because they are the heavenly realities. These realities include the heavenly city and heavenly beings (i.e., angels and believers). Everything about this vision encourages us to come boldly into God's presence (cf. 4:16).
The phrase "the general assembly and church of the first-born"--the Greek construction suggests one group--probably refers to all those believers who had died but will receive their full inheritance.422
"To come to the church of the firstborn' means to be called to the privilege of being a firstborn son. All Christians are called to be part of that assembly and by birth have a right to be there. However, they may forfeit that right and never achieve their calling. That is the thrust of all the warnings of the book of Hebrews."423
The first-born was the son who received the greatest amount of inheritance. This is another reference to Christ's companions (1:9; 3:12) who are partakers of His glory (3:14; 6:4; 12:8), namely, those who faithfully persevere in their faith.424Their names are on a heavenly roll as those who died cleaving to the Lord (cf. Exod. 32:33; Ps. 68:29; Isa. 4:13; Dan. 12:1; Luke 10:20; Phil. 4:3; Rev. 3:5; 13:8; 20:12).425
"The spirits of righteous men made perfect"evidently refers to all the glorified redeemed, faithful and unfaithful, whom Christ's sacrifice has perfected (cf. 10:10, 14; 11:40).
Jesus' blood is better than Abel's because it did not cry out for justice and retribution as Abel's did (cf. 11:4; Gen. 4:10).426It satisfied God's demands and secured God's acceptance of New Covenant believers (cf. 9:12, 26; 10:10, 14, 19). It cried out to God for mercy and pardon for those for whom Jesus shed it.
"It must be acknowledged that the reference to Abel in v. 24b is unexpected, because it does not belong to the developed comparison between Sinai and Zion. It may have been suggested by the reference in v 23b to the presence of pneumasi dikaion, the spirits of righteous persons,' in the heavenly city, since the writer had specified in 11:4 that Abel was attested by God as dikaios, righteous.' It may also have been the writer's intention to evoke the whole history of redemption, from the righteous Abel to the redemptive sacrifice of Jesus, mediator of the new covenant . . ."427
This comparison (vv. 18-21 and 22-24) should motivate us to remain faithful and thereby realize the superior blessings of the New Covenant.
