The sacrifice by which Christ established the holiness of the heavenly tabernacle and the worshipers is the same sacrifice by which He maintains that holiness. He offered His sacrifice for sins once for all time forever perfecting those worshipers He sanctified.
Having put before us the contrasts between Jesus the Son and the prophets in Heb 1:1-3 and the angels in Heb 1:4-14 and 2:5-18, the writer of Hebrews continues to increase our esteem for Christ by turning in chs. 3–10 to the contrast between the Son and Moses and the Levitical priests. Beginning in 3:1-6, we’re told that Jesus is the faithful Son over God’s house and the builder thereof; Moses is a faithful servant in God’s house. To understand better the different roles of Jesus and Moses relative to God’s house, it helps us to consider the house’s two forms. One of those forms appeared in Exod 20–23, where God required “the house of Jacob” (Exod 19:3) to be holy as He is holy (Exod 19:6; Lev 19:2) so as to become His holy nation of priests (Exod 19:4-6). A second form of God’s house came into view in Exod 25–31 and 35–40, where the earthly tabernacle was built after the pattern of God’s holy residence in heaven (Exod 25:40; Heb 8:5) according to His word and by His Spirit. In fact, the tabernacle stood as a shadow and type of what the house of Israel was required to be, namely the living and holy house built when God’s Spirit effectually applied His word to His people. Noticeably, what these two forms of God’s house have in common is the holiness required of them, and to understand how they were sanctified is to gain an even more reverent esteem for Christ. So let’s look further at how God’s house was sanctified.
As summarized in 9:11-28, the sanctification of God’s house in its two forms was accomplished through the priesthoods of Moses and the Levites and of Christ. Under God’s servants Moses and the Levites, God’s house was sanctified when Moses inaugurated the first covenant, cleansing the earthly tabernacle and the worshipers with the blood of calves and goats for his own sins and for those of the worshipers.
