The Ten Commandments are a set of laws for human life, and breaking these rules for living is considered a sin, or violation. But the Bible lists a number of other sins, including one that God says is unpardonable.

The Ten Commandments 101

The Ten Commandments are a set of 10 laws that God issued to Moses. They are found in the books of Exodus 20:1-17 and Deuteronomy 5:4-21. Catholicism considers them as “divine law” because it was revealed by God himself. According to the “for dummies series,” They are considered Commandments from God for the purpose of our own protection. Obey them in eternal happiness is yours.

1. “I am the Lord thy God, You shall not have any strange gods before Me. You shall not make unto thee any graven image.”

2. “You shall not take the name of the Lord thy God in vain.”

3. “Remember to keep holy the Sabbath day.”

4. “Honor thy father and mother.”

5. “You shall not murder.”

6. “You shall not commit adultery.”

7. “You shall not steal.”

8. “You shall not bear false witness against thy neighbor.”

9. “You shall not covet thy neighbor’s wife.”

10. “You shall not covet thy neighbor’s goods.”

Jesus’ Emphasis of the Ten Commandments

Jesus quoted the Ten Commandments and elucidated deeper meaning. For the sixth commandment on adultery, Jesus said:

“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart”

– Matthew 5:27-28.

What’s the Greatest Commandment?

Jesus was asked by the Pharisees which of the ten Commandments was the greatest? “Teacher, which is the greatest commandment in the Law?” Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.”

– Matthew 22:36-40

When you consider Jesus meaning here, it becomes clear that if one follows these two commandments, on the other eight are obeyed as a result.

Which Violation of the Ten Commandments Is the Worst Sin?

The late Reverend Billy Graham said the worst violation of the ten Commandments is not following the first – loving God. Graham writes: “The Bible tells us that the first and greatest commandment is to love the Lord “with all your heart, with all your soul, and with all your mind” (Matthew 22:37). Violating this command is what constitutes the worse sin.”

To love God means to put Him first, above all else. Even above your spouse, children, family or country.

Degrees of Sin and Forgiveness Through Christ

“Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.”

– Galatians 5:19-21

The Bible tells us that everyone sins. It is the nature of humans after falling from grace following Adam and Eve’s original sin.

“For all have sinned and fall short of the glory of God.”

–Romans 3:23

“All wrongdoing is sin, and there is sin that does not lead to death.”

–1 John 5:17

This indicates two things. First, it indicates there are degrees of sin. Second, it acknowledges the mandatory penalty for sin is death. At the same time, it reminds us that sin can be forgiven, through God’s grace. Why? Because Christ’s death on the cross took the penalty on our behalf. Therefore, when one accepts Christ as their Savior, one can escape the death penalty.

“For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

– Romans 6: 23

Which Sin Is Unpardonable? Only One.

Jesus said that any sin and blasphemy can be forgiven by God. However, he said there is only one type of sin that will not be forgiven.

“And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.”

– Matthew 12:31-32
