Sin is a concept that is central to Christian theology and practice. At its most basic, sin refers to any act, thought, or behavior that goes against God’s will. The Bible presents sin as an intrinsic part of human nature due to original sin, but also emphasizes the possibility of redemption and salvation through faith in Jesus Christ. Here is an overview of how the Bible defines and describes sin.
Sin as Disobedience to God
One of the most common ways the Bible defines sin is as an act of disobedience against God’s commands and law. 1 John 3:4 states, “Everyone who practices sin also practices lawlessness; and sin is lawlessness.” Going against God’s moral law and standards is viewed as rebellion against God’s sovereignty and authority. The Ten Commandments given to Moses represent God’s expectations for moral behavior. Breaking any of these commandments was considered sinful (Exodus 20:1-17). Even failure to perform positive duties commanded by God was considered sin, such as neglecting the poor (James 4:17). In summary, sin is failing to do what God commands and doing what God prohibits.
Sin as Missing the Mark
Some Greek words translated as “sin” in the New Testament convey the idea of missing the mark or target. For example, hamartia refers to going off course or missing a goal. Sin represents moral failure to live up to God’s perfect standard of righteousness (Romans 3:23). No human can ever achieve moral perfection outside of Christ. Also, this definition of sin implies that motives and intentions behind actions matter just as much as external behavior. Obeying God’s law for the wrong reasons constitutes sin, even if outward acts conform to the law (Matthew 5:28, 15:8). Overall, this view of sin focuses less on discrete acts and more on the inward moral condition of humans that leads to those acts.
Sin as a Power or Force
At times, the Bible presents sin as a power or force that controls and enslaves people. Paul personifies Sin as an evil taskmaster reigning over mankind in Romans 6-7. Sin is depicted as an innate compulsion that lurks within human hearts, continually causing them to oppose God’s ways. This inner propensity toward sin controls people almost like an addiction, according to Paul. Even when people want to do good, their fleshly desires and thinking drag them down into sin (Romans 7:14-24). Only the saving power of Christ can free someone from sin’s dominion (Romans 6:6-7). This conception of Sin as a slave master illustrates how habitual and ingrained sinful tendencies are.
Sin as Inherited Depravity
Due to the fall into original sin, humans are seen as inherently sinful beings. According to Psalm 51:5, “I was brought forth in iniquity, and in sin did my mother conceive me.” People do not become sinful over time but are born in sin. Mankind inherits a sinful nature from Adam and Eve, the original sinners (Romans 5:12). This inborn inclination toward sin is known as “inherited depravity.” As descendants of Adam and Eve, all humans participate in sin and its consequences (Isaiah 64:6). No one had to teach people how to be bad; it comes naturally. This teaching emphasizes the universal human problem of sin.
Sin as Unbelief
The most serious form of sin highlighted in Scripture is willful unbelief and rejection of God. The Pharisees’ refusal to accept Jesus as the Messiah was denounced by Christ as the blasphemy against the Holy Spirit (Matthew 12:31). John 16:9 claims the ultimate sin is not believing in Christ. Romans 14:23 says, “For whatever does not proceed from faith is sin.” At its root, sin emerges from distrust and failure to acknowledge God for who He is. Pride, arrogance, and the illusion of human autonomy keep people from submitting to their Creator. Whenever humans do not glorify God as God, this constitutes sin in its worst form (Romans 1:21). Scripture presents idolatry, atheism, and agnosticism as heinous sins, since they nullify God and make something else ultimate in a person’s life.
Varieties of Sin
The Bible contains many examples of specific sins condemned by God beyond general unbelief and lawlessness. Jesus said evil intentions and acts like murder, theft, adultery, greed, and slander defile people (Mark 7:20-23). Other moral failings like lust, lying, drunkenness, and envy are repeatedly labeled as sins throughout Scripture (Galatians 5:19-21, Colossians 3:5-9, 1 Corinthians 6:9-10). Hebrews 3:12 indicates unbelief, apostasy, and faithlessness all count as forms of sin. 1 Corinthians 6:18 warns against sexual immorality as sin, while 1 John 2:15-16 warns against loving worldly things more than God. Scripture is clear that all people sin in thought, word, and deed each day (Romans 3:9-20). Even good works become sin when done from wrong motives or when people rely on them for salvation (Isaiah 64:6). Any violation of conscience also brings sin (James 4:17, Romans 14:23). Overall, the Bible depicts sin in its manifold manifestations rather than narrowly defining it.
Sin Leads to Death and Judgment
Scripture constantly warns about the deadly consequences of sin. The wages of sin is death according to Romans 6:23. James 1:15 depicts sin as giving birth to death through a progressive cycle of temptation, enticement, and ungodly desire. Unrepentant sin eventually brings forth death. Ezekiel 18:20 also states that the person who sins will die spiritually. Ephesians 2:1 describes people mired in sin as “dead in transgressions.” The end result of a life of sin is eternal separation from God, often described as the “second death” (Revelation 21:8). Even believers experience God’s discipline and chastisement when engaging in sin (Hebrews 12:5-6). Besides death, persisting in sin renders people objects of God’s wrath at the future judgment (Colossians 3:6, Romans 2:5). The message is clear that indulging sin leads to death and judgment.
Deliverance from Sin through Christ
Though portraying the power of sin, the Bible also promises liberation from its rule and consequences through faith in Christ. Jesus’ death provides atonement for sins (Romans 3:25, Hebrews 9:26). His resurrection empowers new life and freedom from sin’s tyranny (Romans 6:4-14). When people repent and believe the Gospel, God forgives their sins and removes its penalty (Acts 2:38, Colossians 2:13-15). The Holy Spirit sanctifies believers over time to eradicate sinful habits and conform them to Christlikeness (Galatians 5:16-26). At Christ’s return, He will banish sin from the world and make believers righteous (Revelation 21:27, 1 John 3:2). God’s grace does not excuse sin but rather delivers people from its control and consequences. Only Christ’s redemptive work can overcome sin and its fruits of death.
In conclusion, the Bible depicts sin in diverse ways. At its core, sin represents rebellion against God and His purposes. Though seemingly intractable, sin meets its match in the saving work of Jesus Christ. God’s plan offers mercy and freedom to sinners, conferring righteousness by grace through faith. The biblical remedy for sin focuses on inner transformation by the Spirit resulting in obedience from the heart. Believers look forward to an eternity free from the presence and practice of sin.
