Nature of sin
The nature of sin is what sin is at its core: rebellion against God, falling short of his holiness, and corruption of the human heart that shows itself in wrong desires, words, and actions.

Sin is rebellion against God expressed in unbelief, disobedience, and moral corruption.
The nature of sin, in biblical theology, is best understood as rebellion against God in thought, desire, word, and deed, together with the fallen condition from which such acts arise. Scripture describes sin as lawlessness, missing the mark, transgression, unrighteousness, and unbelief, showing that sin is both an inward moral corruption and an outward violation of God’s commands. Conservative interpreters commonly affirm that sin is universal after the fall and that it affects the whole person: mind, will, affections, and conduct. Care should be taken not to reduce sin to mere external rule-breaking, but also not to claim that every person is as evil as possible in every respect. The safest conclusion is that sin is a real moral and spiritual disorder before God that incurs guilt, distorts human nature, disrupts fellowship with God and others, and leads to death unless forgiven and overcome through Christ.
From Genesis 3 onward, Scripture traces sin as humanity’s turning from God’s word, followed by shame, blame, alienation, judgment, and death. Later biblical writers treat sin as a pervasive reality that infects both Israel and the nations, and the New Testament deepens the diagnosis by showing that sin reaches the heart and requires redemption through Christ.
Across Christian theology, sin has been described as both act and condition: a violation of God’s law and a deep moral disorder in fallen humanity. Historic evangelical teaching usually emphasizes the biblical witness to universal sinfulness, personal responsibility, and the necessity of grace, repentance, and the new birth.
In the Old Testament world, sin was understood not merely as a social mistake but as covenant breach against the holy God of Israel. Terms for sin often carry the ideas of missing the mark, guilt, perversity, and transgression. Second Temple Jewish literature expands some of these themes, but Scripture remains the controlling authority for defining sin.
Common biblical terms include Hebrew ḥaṭṭā’t/ḥaṭṭā’t and related words for sin, iniquity, and transgression, and Greek hamartia, anomia, and parabasis. These terms show that sin involves both failure to meet God’s standard and active violation of it.
The doctrine of sin explains why humanity needs redemption, why Christ’s atoning work is necessary, and why repentance and faith are essential. It also guards against minimizing guilt, excusing rebellion, or imagining that human improvement can replace divine grace.
Biblically, sin is not a mere flaw in human development or a social construct; it is a moral failure before a personal, holy God. It includes culpable choices, corrupted desires, and inherited fallenness, so it must be addressed at both the level of conduct and the heart.
Do not collapse sin into only outward acts, as though motives and desires were morally neutral. Do not flatten all sin into the same visible severity; Scripture recognizes degrees of guilt and consequence. Also avoid importing a deterministic view that removes real human responsibility.
Christian traditions differ on how to relate original sin, inherited corruption, and personal guilt, but mainstream evangelical interpretation agrees that all people are sinners and need God’s saving grace. This entry is stated broadly enough to fit that consensus without forcing a particular theological system.
This entry affirms the biblical universality of sin, human accountability, and the need for repentance and salvation in Christ. It does not define sin by psychology, sociology, or philosophy apart from Scripture, and it does not treat sin as only a corporate problem with no personal culpability.
A biblical understanding of sin leads to humility, self-examination, repentance, dependence on Christ, and compassion toward others. It also shapes preaching, counseling, holiness, and the church’s call to confess and forsake sin.
