6 but Christ as a Son over His own house, whose house we are if we hold fast the confidence and the rejoicing of the hope firm to the end.
Verse 6 shows, to the unstable readers of Hebrews, the relevance of the superiority of Jesus over Moses. This verse confronts the readers with their own confidence in the person of Christ.
6 but [on the other hand] Christ
The name “Christ” means messiah, the anointed one. Christ occupied a vastly greater position in God’s house as the Messiah. He is the Son who has a much greater place than a servant.
as a Son over His own house [the family of God],
Moses was a faithful servant in someone else’s house, but Jesus was a faithful Son over His own house. The word “own” designates a house different from Moses’ house. The Son’s house is the people of the present economy of the church.
whose house we are
Christians are the Son’s house, the church (1 Ti 3:15). They are to engage in the activities of Christ’s house.
Those who are truly part of Christ will continue with confidence in what they believe.
Those who constitute Christ’s house will continue in it with confidence that does not wane.
It is possible to lose our appreciation of our privileges as believers in Christ. We can do this by putting undue attention on things of this present life rather than on Christ and our prerogatives in Him. We can lose our grasp on eternal things.
