What Does the Bible Say About Swearing and Foul Language? Words carry enormous power. In an age where profanity saturates entertainment, social media, and even casual speech, Christians face a serious question: does foul language matter to God? Scripture gives a clear and challenging answer.

Gluttony: The Overlooked Sin. In a culture obsessed with food, indulgence, and endless “all you can eat,” gluttony has become the sin no one wants to talk about. Yet the Bible speaks with striking clarity. Gluttony is not merely eating a large meal on a holiday; it is a pattern of overindulgence that treats appetite as a master. Scripture names it alongside drunkenness, greed, and idolatry—yet in many Christian circles it is scarcely mentioned.

Resisting Sexual Temptation: Lessons from Joseph and the New Testament. Sexual temptation is not new. From ancient Egypt to the digital age, God’s people have faced the pull of desire, secrecy, and compromise. Joseph’s encounter with Potiphar’s wife (Genesis 39) stands as one of the most powerful examples of resisting temptation.

Cain: The Firstborn and the Way of Sin. Cain, the firstborn son of Adam and Eve, holds a tragic place in biblical history. His story is brief yet profoundly impactful, marking the first human act of murder and the beginning of humanity’s long history of violence. Cain’s life illustrates the consequences of sin left unchecked, the distortion of worship, and the mercy of God even in judgment.

Adam: The First Man and the Fall of Humanity. When we open the pages of the Bible, we are immediately introduced to the first human being: Adam. His life sets the tone for the human story, a mixture of beauty and tragedy, hope and failure. Adam is more than just the first man; he represents humanity’s capacity for relationship with God and our desperate need for redemption.

Satan’s Fall and the Doctrine of Original Sin: Refuting Isaiah 14 and Ezekiel 28 Misuse. For centuries, many have quoted Isaiah 14 and Ezekiel 28 as if they provide the definitive story of Satan’s fall from heaven. But a closer look at the context shows these chapters are not about Satan at all. Instead, they are prophetic oracles against human kings.

The Fruit of the Spirit vs. the Sin of the Flesh: Evidence of Salvation. The Christian life is not defined merely by what we claim with our lips but by what is produced in our lives. Jesus said, “You can identify them by their fruit, that is, by the way they act… A good tree can’t produce bad fruit, and a bad tree can’t produce good fruit.” (Matt. 7:16, 18, NLT). Paul echoes this in Galatians 5, contrasting the works of the flesh with the fruit of the Spirit. 

What Is Sin? A Biblical, Theological, and Practical Treatment. Sin is more than just “doing bad things.” Biblically, sin is missing the mark—falling short of God’s holiness and will. It is lawlessness (1 John 3:4), rebellion (Isaiah 1:2), and unbelief (Romans 14:23). But it’s also deeper than behavior—it's a condition of the heart.

Sexual Sin: What the Bible Really Says. Few topics in the church today are as controversial—or as muddied—as sexual morality. Modern culture pressures believers to either revise or soften biblical teachings to fit contemporary values. Meanwhile, many churches avoid the subject entirely, hoping silence will preserve peace. But silence never produces righteousness.

Repentance: The Forgotten Command of the Gospel. In modern evangelical vocabulary, repentance has been quietly sidelined. While "faith," "grace," and "blessing" dominate contemporary Christian language, repentance—once foundational to Gospel preaching—is often diluted or discarded altogether. Yet, Scripture places repentance at the very threshold of salvation. The Gospel begins with it, the apostles proclaimed it, and the final chapters of Revelation demand it.

Pride: The Sin That God Actively Opposes. In today’s world, pride is considered a virtue. We are encouraged to take pride in our work, our families, our identities, and even our sin. But Scripture tells a very different story. In the Bible, pride is always a sin.

Pornography: Defiling the Image of God. In a world saturated with visual temptation, the word pornography has become almost sanitized by frequency. But biblically speaking, its roots are profoundly damning. The Scriptures do not speak of “pornography” as a modern category, yet the sin it describes—lust, objectification, sexual immorality—is addressed repeatedly and unequivocally.

Lying is so deeply embedded in human behavior that it often passes without conscience. We call it strategy, diplomacy, or even kindness. Culture teaches us to bend the truth if it means avoiding offense or gaining advantage. But Scripture never offers such latitude. From Genesis to Revelation, lying is condemned without exception—not merely as a mistake, but as a reflection of Satan’s nature and a pathway to eternal judgment.

Idolatry is not ancient history. Though few today bow to carved statues, the human heart remains no less prone to misplaced worship. In fact, idolatry may be the single most common theme in Scripture—and the most underestimated sin in the modern church.

Hypocrisy: Wearing a Mask Before God. Few charges sting more than “hypocrite.” Even unbelievers instinctively know that pretending to be righteous while harboring unrepentant sin is spiritual fraud. Jesus reserved His fiercest rebukes—not for prostitutes or tax collectors—but for religious actors who loved applause more than obedience. In Scripture, hypocrisy is never a petty fault; it is soul-rot that poisons witness, hardens hearts, and invites judgment.
