What Is Sin According to the Bible?
The Bible does not define sin by cultural standards, personal feelings, or social consensus. Sin is defined by God’s law and character. Scripture consistently presents sin as a serious offense against God, not merely a mistake or weakness.
Understanding sin biblically is essential because it explains why salvation is necessary and why the gospel matters. When sin is misunderstood, grace is minimized and redemption becomes unnecessary.
1) The Biblical Definition of Sin
Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
1 John 3:4 (KJV)Scripture defines sin as lawlessness. The Greek word translated “sin” is hamartia (ἁμαρτία), meaning to miss the mark or fall short. Sin is not measured by intention alone but by failure to conform to God’s revealed will.
2) Sin as Rebellion Against God
Sin is not merely breaking rules; it is rebellion against God’s authority. The Bible presents sin as a moral offense that violates God’s holiness and righteousness.
Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
Psalm 51:4 (KJV)David acknowledges that sin is ultimately against God. While sin affects others, its primary offense is against the One whose law has been violated.
3) The Universality of Sin
Scripture teaches that sin is universal. No person is exempt from guilt before God.
For all have sinned, and come short of the glory of God;
Romans 3:23 (KJV)“All” leaves no exceptions. The Bible presents sin as a shared condition of humanity, not merely isolated acts committed by a few.
4) The Consequences of Sin
Sin carries consequences that Scripture does not minimize. The ultimate consequence of sin is death and separation from God.
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Romans 6:23 (KJV)“Wages” implies earned payment. Sin earns death, while eternal life is given as a gift. This contrast highlights both the seriousness of sin and the generosity of God’s grace.
5) Why Sin Matters
Sin matters because it explains humanity’s separation from God and the necessity of salvation. Without understanding sin, the cross of Christ loses its meaning.
But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.
Isaiah 59:2 (KJV)The Bible presents sin as the problem that only God can solve. This prepares the way for understanding grace, forgiveness, and redemption through Christ.
Conclusion
According to the Bible, sin is transgression of God’s law, rebellion against His authority, and a universal condition with serious consequences. Scripture defines sin clearly so that grace may be understood properly. Only by recognizing sin can a person understand the need for salvation through Jesus Christ.
