Read Introduction to Hebrews

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.


if we hold fast [retain, occupy] the confidence [courage, boldness]

The “if” here constitutes a warning to remain firm in or confident in the assurance of what one believes. The word “confidence” conveys the idea of boldness. If believers hold to a bold faith in the face of the temptation to revert to previous belief, they will approach God with confidence (He 4:14; 10:23). Christians are to “retain” public boldness in their Christian walk.

The “if” is not a condition for becoming or remaining a Christian but is evidence for being a believer. Believers belong to Jesus’ house only on the ground of their faith. Those who lose their confidence and hope show evidence that they have failed to appreciate their privileges in Christ.

This phrase does not mean that we will be saved if we hold on until the end. That would mean we would save ourselves or keep ourselves in God’s kingdom. The idea from the argument of the book is that former Jews who became believers in Christ were to resist reverting back into Judaism. It is not right to revert to Moses when Jesus is superior to even someone as great as Moses. Our standing before God does not depend on our good works but on the work of Christ. It is solely by unadulterated grace.

The “if” clause in “if we hold fast the confidence” is conditional on the person’s will; maybe they will or maybe they will not hold fast to their confidence (third-class condition). This condition shows that not all believers will keep their confidence to the end.

The clause “if we hold fast” is followed by another hypothetical conditional clause in the next verse—”if you hear His voice.” Believers may or may not respond to God’s message (He 12:19-20, 24-25; 13:22). The argument in context is the faithfulness of Moses and Christ, with His being superior. None of us is as faithful as the Lord; that is not the argument of this passage.

It is important to note that the hypothetical idea here in 3:6 is explained further in 3:7-4:14. The conditional clause in this verse, “if we hold fast our confidence,” refers to the priestly worship of believers. By returning to the Mosaic system of sacrifices, the Hebrew readers would lose their confidence in the finished work of Christ. If they did not “hold fast,” then they would no longer be able to participate in their priestly worship role provided by Christ (He 10:19-25). If they did not hold fast, then they were in danger of jettisoning their confidence (He 3:6, 14; 10:23–25, 35–39). The believer-priest function gives confidence. This forms the background to the passage that follows (He 3:7-4:14).

The context argues for the believer’s priestly activities (1 Pe 2:5). These people were addressed as “holy brethren” and “partakers of the heavenly calling.” Thus, to “hold fast” is an exhortation for Christians to grow in their faith. The danger is failure to mature in what is believed (He 3:7-19). That failure will lead to temporal discipline from God. If we are faithful, then we will enter God’s “rest” (He 4:1-13).


We maintain stability in the Christian faith by unyieldingly continuing our confidence in the finished work of Christ.


We will remain loyal to Christ if we remain confident in our heavenly inheritance. That is why it is important to “consider Him” (He 3:1).  We consider what He did for us in saving our souls eternally.

The argument of this verse is not that we are to keep ourselves saved. Neither does it show how we are to become Christians. The idea is that assurance is central to a maturing faith. The danger is that reversion will blunt the spiritual growth of those who do not “hold fast” to the content of what they believe (He 10:36). Those who fail to hold fast will experience God’s temporal discipline (He 3:7-19). Those who do hold fast will enter God’s “rest” (He 4:1-13).

The exalted Son of God presides over a priestly apparatus that is operative throughout the Christian life. As long as believers hold firmly to their Christian profession, they will function within the benefits of Christ’s priestly apparatus. It is possible for a believer to step outside his own priestly role.
