Sin

Sin is not failure to meet a moral standard. It is rebellion against God. The first act of human sin in Genesis 3 is not a mistake made in ignorance; it is a deliberate choice to distrust God’s word, to believe a rival account of reality, and to claim for mankind what belongs to God alone: the knowledge of good and evil. Sin is, at its root, the creature refusing to be a creature.

The consequences are immediate and total. Mankind is driven from the presence of God, the ground is cursed, relationships are broken, and death enters the world. These are not arbitrary punishments but the natural result of turning away from the source of all life and goodness. Every subsequent account of human sin in Scripture extends what Genesis 3 describes: the same pattern of distrust, self-assertion, and the refusal to submit to Yahweh’s word.

The Bible uses several words for sin that together describe its full weight: transgression (crossing a boundary God has set), iniquity (a twisting or perversion of what is right), and sin itself (missing the mark of what God requires). None of these words soften what sin is. The Bible does not describe sin as weakness, limitation, or failure to reach full potential. It describes sin as guilt, as a moral debt that must be paid, and as a condition from which mankind cannot free himself.

What is original sin?

Adam’s sin was not a private failure that ended with him. Paul explains that it broke the human race at its root: “just as through one man sin entered into the world, and death through sin, and so death spread to all men, because all sinned” (Romans 5:12). Every person is born already under sin’s consequence, not because Adam’s guilt is unfairly transferred, but because Adam stood as the representative head of the human race, and his fall was the human race’s fall.

How does the Bible say to deal with sin?

Scripture does not tell sinners to try harder or manage their guilt privately. It tells them to confess. John writes plainly: “If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9). Forgiveness is not earned by the confession itself; it rests on God’s own faithfulness and righteousness, secured by what Christ has already accomplished.

Is It a Sin to Get a Tattoo?

Leviticus gives Israel an explicit command: “you shall not make any cuts in your body for the dead nor make any tattoo marks on yourselves: I am Yahweh” (Leviticus 19:28). This command sits among the ceremonial and civil laws given to Israel in the context of pagan mourning rites, where surrounding nations cut and marked their bodies as part of grief rituals and devotion to false gods. It kept Israel visibly distinct from those practices. Christians are not bound to that ceremonial law the way Israel was; it pointed forward to Christ and finds its fulfilment in him. But the principle behind the command still carries weight: the body belongs to God, and marking it is not a decision made in isolation from him. Whether a tattoo is wise, and what it communicates, has to be weighed under that principle rather than treated as a settled command binding every believer today exactly as it bound Israel.

Is It a Sin to Drink Alcohol?

The Bible does not command total abstinence from alcohol, but it is direct about drunkenness: “do not get drunk with wine, for that is dissipation, but be filled with the Spirit” (Ephesians 5:18). Wine is treated elsewhere in Scripture as one of God’s good gifts, and Christ himself made wine at Cana and used it at the Last Supper. What Scripture names as sin is not the substance but the loss of self-control that comes from drinking to excess, control that belongs to the Spirit, not to wine. Proverbs adds its own sustained warning about where drunkenness leads: mockery, brawling, poverty, and ruin. The line Scripture draws is not between drinking and not drinking. It is between moderate use received with gratitude and drunkenness, which it names plainly as sin.

Is It a Sin to Swear?

Paul instructs the Colossians to put away “wrath, anger, malice, slander, and abusive speech from your mouth” (Colossians 3:8), naming the kind of speech believers are to lay aside as part of putting off their old way of life. Coarse language and abusive speech are not minor lapses in politeness. Jesus traces all sinful speech back to the same source: “the mouth speaks out of that which fills the heart” (Matthew 12:34). What comes out of the mouth exposes what actually fills the heart. Swearing, in this sense, is not simply a matter of manners to be cleaned up for appearances. Scripture names it as sin, and calls believers to a different kind of speech altogether: words that build up rather than tear down.
