Christ Jesus is superior in every category. He is superior as High Priest. Now, the Hebrews author writes how Messiah is the superior sacrifice for our sins.
Messiah’s Blood Was the Acceptable Sacrifice
19 Therefore, brethren, having boldness to enter the Holy of Holies by the blood of Jesus,
[In the old covenant, only the High Priest could enter the Holy of Holies (Leviticus 16:2) and even then, only once a year. He had to offer a sacrifice for his own sins before he could do anything else. We can be bold to enter heaven’s Holy of Holies because our High Priest, Jesus, offered His blood as a perfect sacrifice and offering].
20 By a new and living way which he has initiated for us through the curtain, that is, his flesh,
21 [Having] a High Priest over the house of God,
22 Let us come near with a true heart in full assurance of faith, [because] our hearts have been sprinkled from an evil conscience and our bodies washed with pure water.
[Adam Clarke explains this well:
Having our hearts sprinkled—Not our bodies, as was the case among the Hebrews, when they had contracted any pollution, for they were to be sprinkled with the water of separation, see Numbers 19:2-10; but our hearts, sprinkled by the cleansing efficacy of the blood of Christ, without which we cannot draw nigh to God.
From an evil conscience—Having that deep sense of guilt which our conscience felt taken all away, and the peace and love of God shed abroad ill our hearts by the Holy Ghost given unto us.
Our bodies washed with pure water—The high priest, before he entered into the inner tabernacle, or put on his holy garments, was to wash his flesh in water, Leviticus 16:4, and the Levites were to be cleansed the same way, Numbers 8:7. The apostle probably alludes to this in what he says here, though it appears that he refers principally to baptisms, the washing by which was an emblem of the purification of the soul by the grace and Spirit of Christ; but it is most likely that it is to the Jewish baptisms, and not the Christian, that the apostle alludes].
23 Let us tightly hold on to the confession of hopeN3 without wavering, for the one who promised is faithful.
24 Let us keep considering one another in order to stimulate love and good works.
25 Do not forsake our meeting together as [is] the practice of some, but encourage [each other] and more so as youp see the Day approaching,
[The importance of meeting together to worship God and honor His Son the Lord Jesus is the effect it has on each of us. Humans are a social community. Those we associate with do affect us. Compare 1 Corinthians 15:33. Associating and helping other believers has a strong effect in helping us grow in faith and Christian life, encourage our Bible reading, study, and prayer, and discourage falling away from the Christian worldview, lifestyle, and character traits. We also would be more likely to listen to our fellow believers and heed their advice and admonition].
