The book of Hebrews was written to first-century Jewish believers who were tempted to slip back into the old covenant system of law-keeping for security and acceptance with God. Chapters 3 and 4 deliver a powerful warning and invitation: Jesus is superior to Moses, and the true “rest” is found by faith in Him alone—not by ongoing ritual observance of the law. The apostle Paul makes the same case even more forcefully in Galatians, confronting any “different gospel” that adds law-keeping as a requirement for salvation or Christian living. Herbert W. Armstrong’s teachings (Armstrongism), which insisted that Christians must keep the seventh-day Sabbath, holy days, clean/unclean meats, and other elements of the Mosaic law to “qualify” for the Kingdom, directly contradict this biblical message. By clinging to the law, Armstrongism turns the gospel of grace into another form of the very bondage the New Testament warns against.
Jesus Is Greater Than Moses—the Son Over the House (Hebrews 3:1-6)
Fix your thoughts on Jesus, whom we acknowledge as our apostle and high priest,” the writer urges. Moses was faithful as a servant in God’s house. But “Christ is faithful as the Son over God’s house—and we are his house, if indeed we hold firmly to our confidence and the hope in which we glory (Hebrews 3:6, NIV).
Moses represented the old covenant and the law given at Sinai. Jesus is the divine Son who built the house. Armstrongism elevated the law (especially the Sabbath command) as an unchanging requirement for true Christians, treating it almost as co-equal with Christ. Hebrews flips this: the servant (law/Moses) has been surpassed by the Son. Clinging to the old system after the Son has come dishonors Jesus and risks the very unbelief the chapter condemns.
The Warning from Israel’s Wilderness Failure (Hebrews 3:7-19)
Quoting Psalm 95, Hebrews recalls how the Israelites saw God’s miracles for forty years yet hardened their hearts in unbelief. They never entered God’s “rest” (the Promised Land) “because of their unbelief” (3:19). The application is urgent:
See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God… We have come to share in Christ, if indeed we hold our original conviction firmly to the very end (3:12, 14).
Armstrongism often flipped this warning to mean that breaking the weekly Sabbath was the ultimate rebellion, like Israel’s disobedience. But the text is clear: the sin was unbelief—refusing to trust God’s promise and instead relying on their own efforts or rituals. Insisting on law-keeping as a qualification for rest is the same heart-hardening unbelief.
The Superior Sabbath-Rest Available Now by Faith (Hebrews 4:1-13)
The promise of rest remains open. Joshua’s generation entered the land but never experienced the ultimate rest, so “God again set a certain day, calling it ‘Today’” (4:7). Then comes the key verse: “There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from their own works, just as God did from his” (4:9-10).
This is not primarily a command to keep Saturday. It is the spiritual rest believers enter today by faith—ceasing from self-effort, law-keeping, and striving to earn God’s favor, just as God rested from creation. The weekly Sabbath was a shadow pointing to Christ (Colossians 2:16-17); the reality is the Son Himself.
Armstrong and his followers taught the exact opposite. They interpreted “a Sabbath-rest” (Greek sabbatismos) as proof that Christians must continue “a keeping of the Sabbath” literally each week as a type of the future Kingdom rest. Without it, they claimed, you could not qualify for salvation or enter God’s rest. This misses the entire point of Hebrews: the rest is entered now by believing the gospel, not by ritual observance. The chapter ends with an exhortation to “make every effort to enter that rest, so that no one will perish by following their example of disobedience” (4:11)—disobedience defined as unbelief, not calendar-keeping.
Galatians: No Other Gospel—We Are Not Under the Law (Galatians 1–5)
Paul’s letter to the Galatians is even sharper. False teachers were pressuring Gentile believers to add circumcision and law-keeping to their faith. Paul calls this “a different gospel” and pronounces a curse on anyone preaching it (Galatians 1:6-9). He writes:
- We know that a person is not justified by the works of the law, but by faith in Jesus Christ… because by the works of the law no one will be justified (2:16).
- I do not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose (2:21).
- The law was added “because of transgressions” and served as a guardian “until Christ came” (3:19, 24). “Now that faith has come, we are no longer under a guardian” (3:25).
- You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace (5:4).
- If you are led by the Spirit, you are not under the law (5:18).
Galatians 4’s allegory of Hagar and Sarah drives it home: the law is the slave woman producing bondage; the promise is the free woman producing heirs. Armstrongism’s insistence on law-keeping as essential for Christians puts people back under Hagar—slavery—when Christ offers sonship and freedom.
The Heart of the Issue: Law vs. Grace, Shadow vs. Reality
Armstrongism’s core error was treating the old covenant law as still binding in its details while claiming to believe in grace. Hebrews 3–4 shows the law (through Moses) could never give true rest—only Jesus the Son can. Galatians proves that adding any part of the law as a requirement for justification or ongoing acceptance with God is “another gospel” that nullifies grace and makes Christ’s death meaningless.
The weekly Sabbath and other commands were good shadows, but the substance is Christ (Colossians 2:17). True rest is not earned by perfect calendar observance; it is received today by simple, ongoing faith in Jesus’ finished work.
The Invitation Still Stands Today
Hebrews 3–4 and Galatians do not merely critique a first-century problem or a 20th-century movement—they issue a timeless, Spirit-empowered call to every generation tempted to trade the simplicity of the gospel for the security of rules. The law was never meant to be the final word; it was a faithful servant that exposed our inability, drove us to our knees, and pointed ahead to the One who could do what the law could never accomplish (Romans 8:3-4). Armstrongism, with its heartfelt zeal for obedience and its deep respect for Scripture, tragically stopped short of the finish line. By insisting that Christians must still “keep” large portions of the old covenant to remain in God’s favor or “qualify” for the Kingdom, it recreated the very yoke Paul condemned and the very unbelief that kept Israel out of the Promised Land.
Yet the author of Hebrews refuses to leave us in despair. He repeatedly shouts the word “Today!”—the day of opportunity, the day of grace, the day when the promise of rest is still wide open. This rest is not a future reward earned by flawless Sabbath observance or dietary law-keeping. It is a present reality entered the moment a weary soul stops striving and simply believes that Jesus, the faithful Son over God’s house, has already done everything required. It is the soul-level sabbath where we cease from our own works the way God ceased from His at creation—fully satisfied, fully accepted, fully at peace.
For anyone who has carried the heavy tablets of Armstrongism—or any form of legalism—the message is liberating and urgent: You do not have to qualify. You only have to believe. The chains of “Sabbath & Works” shatter not by greater effort but by looking to the radiant Christ who stands with open arms. Galatians 5:1 rings like a victory shout:
It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.
True obedience does not disappear in this rest—it is transformed. No longer motivated by fear of disqualification, it flows from love for the Savior who fulfilled the law on our behalf. The Spirit who lives in every believer now writes God’s character on our hearts (Jeremiah 31:33; Ezekiel 36:26-27), producing fruit that the law could only demand but never create.
If you are reading this and sensing the Holy Spirit stirring your heart, hear the final invitation of Hebrews:
Let us then approach God’s throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need (Hebrews 4:16).
The old covenant has served its purpose. The new has come. Rest is here—today—in Christ alone. May you receive it, walk in it, and proclaim the glorious freedom of the gospel to everyone still bound by the very system the New Covenant came to release us from.
