Hebrews 3: Harden Not Your Heart

Read Hebrews Chapter 3

Introduction: Hebrews 3 stresses the fact of Jesus Christ’s superiority over Moses and cautions believers to heed God’s voice and not harden their hearts as the Israelites did in the wilderness. This chapter warns against unbelief and encourages believers to remain steadfast in their faith. We will look at the key themes and exhortations in this chapter, as well as cross reference verses, to give us a deeper understanding of Hebrews 3, and a stronger commitment to faithfulness in Christ.

I. The Superiority of Jesus to Moses (Hebrews 3:1-6)
Hebrews 3:1-6 compares Jesus to Moses, pointing out Jesus’ greater glory and authority. Jesus is described as the apostle and high priest of our confession, faithful to God who appointed Him. Hebrews 3:1 acknowledges believers as holy brethren and partakers in the heavenly calling, urging them to consider Jesus. 1 Peter 2:9 describes believers as a chosen generation, reinforcing their holy status and calling. Hebrews 3:2-3 highlights that Jesus was faithful just as Moses was, but Jesus is worthy of more glory, much like a builder has more honor than the house. Numbers 12:7 commends Moses for his faithfulness in God’s house, showing the high regard for Moses that is now surpassed by Jesus. Hebrews 3:4-6 further explains that while every house is built by someone, God is the ultimate builder. Moses was a servant in God’s house, but Christ is the Son over God’s house, which is comprised of believers. 1 Corinthians 3:16 reminds us that believers are God’s temple, and God’s Spirit dwells within us, emphasizing the importance of the spiritual house over which Christ presides.

II. A Warning Against Unbelief (Hebrews 3:7-19)
In these verses, the Hebrews writer warns the readers about the dangers of unbelief, using the example of the Israelites who failed to enter God’s rest (the promised land) because of their hardened hearts. Hebrews 3:7-11 quotes Psalm 95:7-11, urging readers to listen to God’s voice today and not harden their hearts as the Israelites did during the exodus. Psalm 95:7-11 is a direct quote and basis for this warning, showing the historical precedence of this caution. Hebrews 3:12-14 cautions against a sinful, unbelieving heart that turns away from God, stressing the need to remain steadfast in the faith. Deuteronomy 29:18 warns against a root bearing bitterness and poison, paralleling the idea of a heart turning away from God. Hebrews 3:15-19 finishes the chapter by reminding readers that it was unbelief that prevented the Israelites from entering the promised rest, serving as a lesson for current believers to maintain their faith. Numbers 14:11-12 recounts God’s frustration with the Israelites’ lack of faith, reinforcing the consequences of unbelief depicted in Hebrews.

Conclusion: Hebrews 3 calls believers to recognize the supremacy of Christ over all, even the very important people like Moses who were central to the faith of Israel. It also soundly warns against the sin of unbelief, using the Israelites as a sobering reminder. The chapter inspires us to hold firmly to our confidence and trust in Christ, who is the faithful Son over God’s house, and to encourage one another in faith so that we may share in the promise of His rest (eternity in heaven). We should, therefore, heed the call to not harden our hearts and to remain grounded in our belief, drawing inspiration from the enduring message of Hebrews 3.
