Sin (1)
What Sin Is: Biblical Definitions
The Bible uses a rich vocabulary to describe sin, each word illuminating a different aspect of the problem. The most common Hebrew term, chatta'th, means "to miss the mark," picturing sin as a failure to hit the target of God's standard. Another Hebrew word, avon, means "perversity" or "crookedness," suggesting a twisting of what is straight. A third, pesha, means "transgression" or "rebellion," emphasizing willful defiance against God's authority.
In the New Testament, the Greek hamartia (also "missing the mark") is the dominant term, while parabasis ("transgression" or "stepping across a boundary") and adikia ("unrighteousness" or "injustice") add further dimensions. Taken together, these terms show that sin is not merely breaking rules but falling short of God's glory (Romans 3:23), twisting what God made good, and rebelling against the Creator's rightful authority.
The apostle John provides perhaps the most concise definition: "Everyone who sins breaks the law; in fact, sin is lawlessness" (1 John 3:4). Sin is fundamentally disobedience to the will and law of God.
The Origin of Sin: The Fall
The Bible traces human sin to a specific event: the disobedience of Adam and Eve in the garden of Eden (Genesis 3:1-7). The narrative reveals the anatomy of temptation with timeless precision. The serpent attacks God's word ("Did God really say?"), questions God's motives ("God knows that when you eat from it your eyes will be opened"), and contradicts God's warning ("You will not certainly die"). Eve sees that the fruit is "good for food and pleasing to the eye, and also desirable for gaining wisdom" (Genesis 3:6), appealing to appetite, aesthetics, and ambition.
The consequences are immediate and comprehensive. The relationship between humanity and God is broken (Genesis 3:8-10). Relationships between people are damaged (Genesis 3:12, 16). The relationship with creation is cursed (Genesis 3:17-19). And death enters the human story (Genesis 3:19; Romans 5:12). The fall is not merely a story about the first humans; it is the prototype for how sin works in every human life.
The Universality and Depth of Sin
The Bible insists that sin is not limited to a few exceptionally wicked people but is universal. "There is no one righteous, not even one" (Romans 3:10). "All have sinned and fall short of the glory of God" (Romans 3:23). The Old Testament makes the same point: "There is no one who does not sin" (1 Kings 8:46); "Surely there is not a righteous man on earth who does good and never sins" (Ecclesiastes 7:20).
Moreover, sin is not merely a matter of outward actions but penetrates to the deepest level of human nature. "The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time" (Genesis 6:5). Jesus taught that sin originates in the heart: "For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander" (Matthew 15:19). External behavior is the fruit; the root is an inner disposition of rebellion against God.
The psalmist acknowledges the depth of this problem: "Surely I was sinful at birth, sinful from the time my mother conceived me" (Psalm 51:5). Paul speaks of humanity being "by nature deserving of wrath" (Ephesians 2:3). This is not to say that every person is as wicked as they could possibly be, but that every aspect of human nature is affected by sin, including the mind, will, emotions, and body.
Sin as a Power
The Bible does not treat sin merely as isolated bad choices but as a ruling power that enslaves. Paul personifies sin as a master: "Don't you know that when you offer yourselves to someone as obedient slaves, you are slaves of the one you obey, whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?" (Romans 6:16). Jesus said, "Everyone who sins is a slave to sin" (John 8:34).
This enslavement explains the frustrating experience described in Romans 7:15-20: "I do not do the good I want to do, but the evil I do not want to do, this I keep on doing." Sin is not just something people do; it is something that has them. This is why moral effort alone cannot solve the human problem. Liberation requires an outside intervention, which is exactly what the gospel provides.
The Consequences of Sin
The Bible describes sin's consequences in several dimensions:
Spiritual death: Sin separates people from God. "Your iniquities have separated you from your God; your sins have hidden his face from you" (Isaiah 59:2). Paul writes that those outside of Christ are "dead in transgressions and sins" (Ephesians 2:1).
Physical death: Death entered the world through sin (Romans 5:12; Genesis 2:17). The entire creation groans under the effects of the curse (Romans 8:20-22).
Judgment: Sin carries the certainty of divine judgment. "The wages of sin is death" (Romans 6:23). The book of Revelation portrays a final judgment where all are held accountable (Revelation 20:11-15).
Relational damage: Sin fractures human relationships, producing conflict, exploitation, and injustice. The immediate aftermath of the fall includes blame-shifting (Genesis 3:12) and murder (Genesis 4:8).
Redemption from Sin
The Bible's teaching on sin is never an end in itself but always points toward God's provision for its remedy. The sacrificial system of the Old Testament provided temporary covering for sin (Leviticus 4-5), while the prophets looked forward to a time when God would deal with sin decisively through a new covenant (Jeremiah 31:34) and a suffering servant who would bear the people's iniquities (Isaiah 53:5-6).
The New Testament proclaims that Jesus Christ is the answer to the problem of sin. "God demonstrates his own love for us in this: While we were still sinners, Christ died for us" (Romans 5:8). Through faith in Christ, sinners receive forgiveness (Ephesians 1:7), freedom from sin's power (Romans 6:6-7), and the indwelling Holy Spirit who enables a new kind of life (Romans 8:2-4). The final hope is complete liberation from sin's presence in the new creation, where "there will be no more death or mourning or crying or pain" (Revelation 21:4).
Biblical Context
Sin is addressed in virtually every book of the Bible. Genesis 3 records the fall. The Mosaic Law defines sin and provides for its atonement (Leviticus 4-6; Deuteronomy 27-28). The historical books illustrate sin's national consequences. The Psalms express confession and the longing for forgiveness (Psalms 32, 51). The prophets diagnose Israel's sin and announce judgment and restoration (Isaiah 1, 59; Jeremiah 17:9; Ezekiel 18). In the Gospels, Jesus confronts both external and internal sin (Matthew 5-7; 15:19). Paul provides the most systematic treatment in Romans 1-8. James, John, and Hebrews also address sin's nature and remedy.
Theological Significance
The doctrine of sin is the necessary counterpart to the doctrine of salvation. Without understanding the depth and universality of sin, the cross appears unnecessary and grace becomes trivial. Sin reveals the holiness of God (who cannot tolerate it), the seriousness of rebellion (which brings death), and the magnitude of divine love (which provides redemption at infinite cost). The Bible's teaching on sin also preserves human moral responsibility: sin is chosen, not merely inherited, and every person stands accountable before God. At the same time, the pervasiveness of sin demonstrates that salvation must come from outside the human condition, pointing directly to the need for a divine Savior.
Historical Background
Ancient Near Eastern cultures had various concepts of wrongdoing and ritual impurity, but the biblical understanding of sin as personal rebellion against a holy, personal God was distinctive. Mesopotamian and Egyptian texts speak of offending the gods, but the moral framework is less developed than in Israel's Scriptures. Greek philosophy tended to view evil as ignorance rather than willful rebellion. The Jewish understanding of sin deepened through the prophetic period and into Second Temple Judaism, with texts like 4 Ezra and 2 Baruch reflecting on Adam's fall and its consequences for humanity. Early church theologians, especially Augustine, developed the doctrine of original sin based on Paul's teaching in Romans 5, establishing categories that have shaped Western theology ever since.
