Christian Ethics and the Nature of Sin
Sin is defined as "any want of conformity unto or transgression of the law of God" [1], encompassing both inward disposition and outward conduct, whether by omission or commission. This definition, rooted in 1 John 3:4 and Romans 4:15, establishes sin not merely as violation of an impersonal system but as "an offence against a personal lawgiver and moral governor who vindicates his law with penalties" [1]. The soul that sins recognizes both the intrinsic vileness of the act and its just desert of punishment [1].
The Biblical Foundation
Scripture presents sin as universal and originating in human nature from birth. Psalm 58:3 declares that "all human beings are born sinners" [5], a condition traced to the fall in Genesis 3, where the first pair's transgression involved "a love of self, dishonor to God, ingratitude to a benefactor, disobedience to the best of Masters—a preference of the creature to the Creator" [7]. Paul's argument in Romans 1:18–3:20 establishes that both Gentiles and Jews stand equally under sin's power, unable to find favor with God through their own actions [8]. God's anger toward sin is not emotional outburst but "the holy God's necessary response to sin" [8].
Sin's Ongoing Reality
Even after regeneration, believers continue to commit actual sins [9]. The distinction matters: "we have no sin" in 1 John 1:8 refers to present guilt from sins committed and the corrupt old nature still adhering, while "we have not sinned" in 1:10 addresses the ongoing commission of actual sins even after conversion [9]. Those who imitate the devil become children of the devil "by imitating him, not by proper birth," for "from the devil there is not generation, but corruption" [6].
The Ethical Response
Christian ethics flows not from philosophical speculation but from doing God's will [10]. Conformity to Christ's example is required in holiness, righteousness, purity, love, humility, and obedience [4]. Where the wicked indulge their sinful nature, the godly fight against it [5]. Forgiveness of sin, a constituent part of justification, absolves the sinner from condemnation through Christ's work, removing guilt and eternal liability [2]. Old Testament law required confession and restitution for wrongs committed [3], establishing that ethical obligation extends beyond internal repentance to external restoration.

- Easton's Bible Dictionary “Easton's Bible Dictionary: Sin — Is "any want of conformity unto or transgression of the law of God" (1 John 3:4; Rom. 4:15), in the inward state and habit of the soul, as well as in the outward conduct of the life, whether by omission or commission (Rom. 6:12-17; 7:5-24). It is "not a mere violation of the law of our constitution, nor of the system of things, but an offence against a personal lawgiver and moral governor who vindicates his law with penalties. The soul that sins is always conscious that his sin is (1) intrinsically vile and polluting, and (2) that it justly deserves punishment,”
- Easton's Bible Dictionary “Easton's Bible Dictionary: Forgiveness of sin — One of the constituent parts of justification. In pardoning sin, God absolves the sinner from the condemnation of the law, and that on account of the work of Christ, i.e., he removes the guilt of sin, or the sinner's actual liability to eternal wrath on account of it. All sins are forgiven freely (Acts 5:31; 13:38; 1 John 1:6-9). The sinner is by this act of grace for ever freed from the guilt and penalty of his sins. This is the peculiar prerogative of God (Ps. 130:4; Mark 2:5). It is offered to all in the gospel. (See [219]JUSTIFICATION.)”

Gentiles (1:18-32) and Jews (2:1–3:8) are equally under sin’s power and cannot find favor with God by any action of their own (3:9-20). 1:18 God’s anger is not a spontaneous emotional outburst, but the holy God’s necessary response to sin. The Old Testament often depicts God’s anger (Exod 32:10-12; Num 11:1; Jer 21:3-7) and predicts a decisive outpouring of God’s wrath on human sin at the end of history. While Paul usually de”
