The Bible identifies many behaviors, thoughts, desires, and attitudes as sinful because they oppose God’s commands or harm our relationship with Him and with other people. These sins are mentioned across many books rather than gathered into one single master list.
Instead of focusing on the broader question of what sin is, this guide organizes sins mentioned in the Bible into clear categories with key Scripture references for quick study. Scripture also raises an important related question about whether every sin carries the same seriousness or consequences, which is explored separately in whether all sins are equal according to the Bible.
Sins Related to Worship and God
Some sins directly concern humanity’s relationship with God. They involve giving worship elsewhere, dishonouring God or seeking spiritual power through practices Scripture condemns.
- Idolatry: Giving worship, devotion or ultimate allegiance to something other than God. Exodus 20:3–5; 1 Corinthians 10:14
- Blasphemy: Speaking about God in a deliberately dishonouring or irreverent way. Leviticus 24:16; Mark 3:28–29
- Sorcery or witchcraft: Seeking forbidden supernatural power or spiritual guidance apart from God. Deuteronomy 18:10–12; Galatians 5:19–21
- Misusing the Lord’s name: Treating God’s name falsely, carelessly or dishonourably. Exodus 20:7
- Worshiping created things: Giving the honour due to the Creator to created beings or objects. Romans 1:22–25
- Testing God: Deliberately demanding that God prove Himself or putting His faithfulness to the test. Deuteronomy 6:16; Matthew 4:7
These sins show that biblical morality begins with worship, loyalty and reverence toward God, not only with outward behaviour toward other people.
Sins of the Mind and Thoughts
The Bible repeatedly addresses sins that begin internally. Attitudes such as jealousy, pride, bitterness and selfish desire can shape outward actions long before others recognize them.
- Bitter jealousy: Resenting another person’s success, possessions, position or advantages. James 3:14–16
- Selfish ambition: Pursuing personal advantage through rivalry, self-interest or disregard for others. Philippians 2:3; James 3:14–16
- Evil desires: Allowing desires contrary to God’s will to control the heart. Colossians 3:5
- Coveting: Desiring what belongs to another person in a possessive or discontented way. Exodus 20:17
- Pride: Exalting oneself and resisting humility before God and others. Proverbs 16:18; James 4:6
- Envy: Resenting the good another person possesses or wishing it belonged to oneself. Galatians 5:26; James 3:16
- Hatred: Harbouring hostility toward another person instead of love and reconciliation. 1 John 2:9–11
- Unforgiveness: Refusing to release resentment or extend forgiveness after being wronged. Matthew 6:14–15; Mark 11:25
Pride, greed, envy and other recurring inner vices later became part of the traditional Christian framework known as the Seven Deadly Sins. That historical framework is useful for studying major human vices, but it is not a complete list of every sin mentioned in Scripture.
Sins of Speech
Scripture gives serious attention to speech because words can deceive, divide, damage reputations or encourage wrongdoing. The Bible therefore treats the use of the tongue as an important moral responsibility.
- Lying: Intentionally communicating what is false or deceptive. Colossians 3:9; Ephesians 4:25
- False witness: Giving dishonest testimony that harms another person or distorts justice. Exodus 20:16; Proverbs 19:5
- Slander: Speaking maliciously or falsely in ways that damage another person’s reputation. Ephesians 4:31; 1 Peter 2:1
- Gossip: Spreading private or harmful information in ways that create betrayal or division. Proverbs 11:13; Proverbs 16:28
- Deceit: Deliberately misleading another person through words or conduct. 1 Peter 2:1; Psalm 34:13
- Corrupt speech: Using words that tear others down instead of helping or strengthening them. Ephesians 4:29
- Coarse joking: Speech characterized by obscenity, foolishness or degrading humor. Ephesians 5:4
- Cursing others: Using speech to attack people who are made in God’s likeness. James 3:9–10
Biblical teaching about speech is therefore broader than avoiding obvious lies. It also concerns whether our words are truthful, necessary, gracious and beneficial.
Sins in Relationships and Injustice
Many sins in the Bible concern the way people treat one another. Scripture repeatedly condemns violence, exploitation, dishonesty, favouritism and the mistreatment of vulnerable people.
- Murder: Unlawfully taking human life. Exodus 20:13; Matthew 5:21–22
- Stealing: Taking money, property or possessions that belong to another person. Exodus 20:15; Ephesians 4:28
- Partiality or favouritism: Treating people differently because of wealth, status, appearance or influence. James 2:1–9
- Oppressing the poor: Exploiting or mistreating people who are economically or socially vulnerable. Proverbs 14:31; Zechariah 7:10
- Defrauding others: Gaining something through dishonest or unjust treatment. Leviticus 19:13; 1 Thessalonians 4:6
- Violence: Using cruelty or force unjustly against another person. Psalm 11:5
- Causing others to stumble: Influencing another person toward wrongdoing or disregarding their spiritual well-being. Matthew 18:6–7; Romans 14:13
These passages show that biblical sin is not only private. Injustice and exploitation can damage families, communities and people who have less power to defend themselves.
Sins Related to Money, Sexuality and Self-Control
Scripture also addresses money, sexual conduct, appetite, anger and other powerful desires. The issue is not that possessions, food, sexuality or emotion exist, but that they can become distorted, uncontrolled or used in ways that Scripture condemns.
- Love of money: Allowing wealth or the desire for wealth to become a controlling motivation. 1 Timothy 6:9–10; Hebrews 13:5
- Greed: An excessive desire for money, possessions or personal gain. Luke 12:15; Ephesians 5:5
- Extortion: Taking money or property through force, abuse of authority, intimidation or exploitation. Luke 3:13–14; 1 Corinthians 6:10
- Sexual immorality: Sexual conduct that Scripture places outside God’s moral boundaries. 1 Corinthians 6:18; 1 Thessalonians 4:3–5
- Adultery: Sexual unfaithfulness within marriage. Exodus 20:14; Matthew 5:27–28
- Lustful intent: Deliberately cultivating sexual desire toward another person in a sinful way. Matthew 5:27–28
- Drunkenness: Allowing alcohol to produce intoxication and loss of sober self-control. Ephesians 5:18; Romans 13:13
- Fits of rage: Explosive or uncontrolled anger that leads to destructive behaviour. Galatians 5:19–21
Some behaviours in this category also appear in New Testament passages warning about those who will not inherit God’s kingdom. Those passages need to be read carefully in context, which is why they are examined separately in who will not inherit the Kingdom of God according to the Bible.
Sins of Omission
Not every sin in the Bible involves actively doing something forbidden. Scripture also recognizes situations in which a person knows what is right but deliberately fails to do it.
James 4:17 expresses this principle clearly: knowing the good that should be done and refusing to do it can itself be sinful. This means biblical obedience involves responsibilities as well as prohibitions.
A person may avoid stealing, lying, or violence yet still fail morally by neglecting compassion, refusing justice, withholding needed help, or ignoring a responsibility they clearly understand. Matthew 25:31–46 also illustrates the seriousness of failing to respond to people in need.
Sins of omission therefore remind us that the biblical question is not only, “What wrong thing did I do?” It can also be, “What good did I knowingly refuse to do?”
