Does Hebrews teach that flagrant sin can never be forgiven?

Can a Christian lose his salvation? This question has long troubled and divided believers. Thousands of pages have been written to give an answer to this burning question. One of the major battlegrounds in this debate is the meaning of various key verses in the book of Hebrews. For example, Hebrews 10:26 says, “For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins.” Does this mean that if someone knowingly sins they lose their salvation and can never enter heaven?

Hebrews quotes the Old Testament over 30 times and makes many more references to people, events and rituals found in the Old Testament. The book of Hebrews was written to Jews who had a broad knowledge of the Old Testament. The modern Christian needs a similar broad understanding of the Old Testament to better understand the book Hebrews.

Hebrews 10:26 points back to the absence in the Mosaic law of any sacrifice for intentional and willful sins. Numbers 15:30-31 says, “But the soul that doeth ought presumptuously, whether he be born in the land, or a stranger, the same reproacheth the LORD; and that soul shall be cut off from among his people. Because he hath despised the word of the LORD, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him.” The Old Testament did not permit a person to plan to sin on Saturday and ask forgiveness on Sunday.

The book of Hebrews was written as a warning to those in the church on the verge of abandoning their profession of faith. The Jewish Christians faced intense persecution because they turned to Christianity. Some buckled under the pressure and turned away from their profession of faith. Hebrews encouraged the wavering believers to remain faithful to Jesus because He is far better than the Judaism they were returning to. There is no salvation in Judaism. Jesus is the only way of salvation. Those who rejected Jesus for their cultural traditions and familial religion were not saved.

Despite the absence of sacrifice for willful sin in the Old Testament, the grace of God was and is greater than sin. When David committed adultery with Bathsheba, he sinned willfully and presumptuously. Does this mean he was never forgiven? In Psalm 51 David was confident God would forgive Him He acknowledged his guilt before God. He understood no sacrifice was available for his sin. However, David did not despair he would never be forgiven. He cried out to God confident He would forgive. He prayed, “Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.” (Psam 51:7) David’s words in Psalm 51 stand today as a Divine promise for all sinners, even those who willfully and rebelliously continue in sin. “The sacrifices of God are a broken spirit: a broken and a contrite heart thou wilt not despise.” (Psalm 51:17) Those who repent of their sin and cry out to God for salvation will be saved.

Hebrews never teaches that salvation can be lost. The entire book emphasizes that Jesus alone is the fully sufficient Savior. He saves to the uttermost. (Hebrews 7:25) Those saved by Jesus can never exceed the limits of His grace. Hebrews not only teaches that Jesus secures the believer’s salvation, He also secures the believer in salvation. Hebrews 10:39 confidently asserts,“We are not of them who draw back unto perdition, but of them that believe to the saving of the soul.” Those who believe to salvation will not draw back, fall away or turn aside. Those who rejected Jesus for Judaism did not lose their salvation, they turned aside from a profession that was not genuine. Those who are genuinely saved will not cast Jesus aside nor be cast aside by Him.
