Hebrews 3

Christ Greater Than Moses and the Warning Against Unbelief

Hebrews chapter 3 builds directly on chapter 2. There the Son was made lower than the angels, tasted death for everyone, was crowned with glory and honor, and was perfected through sufferings so that He might bring many sons to glory.

Jesus stands as the merciful and faithful High Priest who makes propitiation and helps those who are tempted. Because that is true, the writer now says, therefore, holy brothers, partakers of a heavenly calling, consider the Apostle and High Priest of our confession — Jesus.

Hebrews calls them holy brothers because Christ has sanctified them. Chapter 2 declared that both He who sanctifies and those who are sanctified are all of one, and He is not ashamed to call them brothers.

Their holiness rests on His once-for-all work. He calls them partakers of a heavenly calling because God has summoned them through the gospel to share in the glory the exalted Son has secured. This calling comes from heaven and directs them toward the rest He has obtained.

Consider Jesus. Fix your mind on Him and keep Him before you. He is the Apostle, sent from the Father to reveal God and accomplish redemption. He is the High Priest of our confession, standing before God on behalf of His people.

Everything we confess rests on Him. In chapter 2 He helps those who are tempted, and here we are commanded to keep looking at Him so that our hearts do not harden against His voice.

Hebrews compares Jesus to Moses. Jesus was faithful to Him who appointed Him, as Moses also was faithful in all God’s house. Moses was a faithful servant. God Himself said so in Numbers chapter twelve.

But Jesus is worthy of more glory than Moses, because the builder of the house has more honor than the house. Every house is built by someone, but the builder of all things is God, and chapter 1 verse 2 has already explained that Christ shares in this divine building role as the Son. Moses was in the house as a servant. Christ is over the house as the Son. Moses bore witness to what would later be spoken, and Christ is the fulfilment of what Moses anticipated.

And we are His house, if we hold fast our confidence and the boast of our hope. We are not the house because we build it. We are the house because the Son built it and rules over it. Holding fast does not secure our place. Holding fast shows that our confidence in Christ is real. Faith that is born of God continues to rest in the faithful Son.

Again and again, Hebrews will show that what came through Moses was real and ordained by God. However, the covenant at Sinai, the priesthood, and the sacrifices all pointed forward to something greater. Israel was called to an earthly inheritance under Moses, but we are called to a heavenly inheritance in the Son. If Christ is the Son over the house, then returning to Moses cannot bring us into rest. The wilderness generation proves that.

The Spirit speaks through Psalm ninety five. Today if you hear His voice, do not harden your hearts as when they provoked Me in the wilderness. That generation came out of Egypt. They saw the blood of the Passover lamb. They walked through the sea. They ate manna and drank water from the rock.

However, in Exodus chapter seventeen at Massah and Meribah, the Israelites tested the Lord, and in Numbers chapter fourteen at Kadesh-Barnea they refused to enter the land He promised. They did not trust His word. God said of them, they always go astray in their heart. So He swore in His wrath, “They shall not enter My rest.” Their bodies fell in the wilderness because of unbelief.

This is why Hebrews 3 says, “See to it, brothers, that there not be in any one of you an evil, unbelieving heart that falls away from the living God.” The issue is the heart and the root is unbelief.

In this chapter unbelief means refusing to trust the Son through whom God has now spoken, as we were told at the beginning of the letter. To turn away from Christ is to fall away from the living God. And in the context of Hebrews, that turning would include retreating from the Son back toward Moses and the covenant mediated at Sinai.

To turn from the faithful Son over the house and place confidence again in the servant within the house is not faithfulness to Moses. It is unbelief in the finished work of the Son who tasted death for everyone and was crowned with glory. Falling away is the outward expression of that inward rejection.

Hebrews 3 continues: But encourage one another day after day, as long as it is still called Today, so that none of you will be hardened by the deceitfulness of sin.

Sin deceives when it whispers that Christ’s death on the cross is not sufficient. The answer is daily exhortation grounded in the truth about Christ, because the same Son who commands perseverance is the One who helps those who are tempted.

We have become partakers of Christ, if we hold fast the beginning of our assurance, firm until the end. We have become partakers of Christ. That is the foundation. To partake of Christ is to share in Him, in His saving work, in His priestly mediation, and in the glory Christ secured in chapter 2.

This does not mean that Christ begins salvation and we must preserve it by our own effort. It means that those who truly share in Christ continue to trust Him. The beginning of our assurance was the confidence we had when we first confessed Him, and that confidence rested entirely on Him as the Apostle and High Priest who accomplished salvation.

Holding fast is faith continuing to cling to that same Savior. Perseverance does not complete what Jesus started. It reveals that His work in us is living and true.

The wilderness generation is recalled once more.

“For who provoked Him when they had heard? Indeed, did not all those who came out of Egypt led by Moses?”

“And with whom was He angry for forty years? Was it not with those who sinned, whose corpses fell in the wilderness?”

“And to whom did He swear that they would not enter His rest, but to those who were disobedient?”

“So we see that they were not able to enter because of unbelief.”

That is the conclusion of the chapter. The issue is not that salvation can be gained and then lost through lack of effort, but that those who refuse to believe do not enter His rest.

An entire generation experienced outward deliverance and yet did not enter because they did not trust the word of God. In the same way, outward association with the people of God is not enough. What matters is persevering faith in the Son.

Hebrews chapter 3 builds on the truth of chapter 2 and draws our eyes toward the promise of entering His rest, the goal of our heavenly calling.

The Son who tasted death and was crowned with glory stands over God’s house as the faithful Son.

Jesus surpasses Moses and He speaks Today. The danger is hardening the heart against Him, and that danger is not limited to returning to the law of Moses.

It includes any movement away from simple trust in the Son, whether by seeking righteousness through obedience, by drifting into indifference, or by shrinking back under pressure. At its root, it is the temptation to believe that Christ is not sufficient.

The answer is to consider Jesus, to encourage one another daily, and to hold fast our confidence in the One who helps the tempted and brings many sons to glory.

We are His house and we are partakers of Christ. Because He is faithful, those who truly belong to Him continue to cling to Him. The warning against departing from Christ is severe, and it is meant to be. It guards us from an evil, unbelieving heart and drives us back to the faithful Son who brings His people into His rest. God has spoken in His Son. And He promises rest to all who believe in Him.
