What Does the Bible Mean by ‘Sin’?
Sin is often softened to a mistake or a weakness. The New Testament word — the Greek hamartia, “missing the mark” — is graver: falling short of God’s glory, and rebelling against Him.
The Three Strands the Word Holds Together
Strand 1Missing the mark
Hamartia pictures an arrow falling short of the target — falling short of God’s glory and standard. “All have sinned and fall short of the glory of God” (Romans 3:23).
Strand 2Lawlessness and rebellion
More than a slip: crossing God’s line. “Sin is lawlessness” (1 John 3:4); it even includes the good left undone (James 4:17). Both wrong deeds and a wrong condition.
Strand 3A power, deadly yet answerable
Scripture personifies sin as a master that enslaves (John 8:34; Romans 6). “The wages of sin is death” (Romans 6:23); yet Christ’s blood “cleanses us from all sin” (1 John 1:7).
What the Key Texts Say

|---|---|---|
| Romans 3:23 | Missing the mark | “All have sinned and fall short of the glory of God.” |
| 1 John 3:4 | Lawlessness | “Whoever commits sin also commits lawlessness, and sin is lawlessness.” |

Two Common Misunderstandings
Sin is not merely mistakes or rule-breaking. It is missing the mark of God’s glory and rebelling against Him — “sin is lawlessness” (1 John 3:4) — a condition of the heart, not only wrong acts; it even includes the good left undone (James 4:17).
Sin is not something we can excuse or outgrow on our own. “All have sinned” (Romans 3:23); “if we say that we have no sin, we deceive ourselves” (1 John 1:8). Its wages is death; only Christ’s blood cleanses it (Romans 6:23; 1 John 1:7).
So, What Is Sin?
Sin is missing the mark of God’s glory and crossing the line of His law — both a wrong condition and wrong deeds, both what we do and the good we leave undone. It is universal, enslaving, and its wages is death; yet its guilt and power are answered by the blood of Christ. Not a small thing, and not a hopeless one.
Sources & Notes Greek word study: hamartia (Strong’s G266), “a missing of the mark, sin,” from hamartano (G264), “to miss the mark, to err, to sin.” In the New Testament it is always ethical, and is even personified as a ruling power that enslaves (Romans 6–7). Scripture also names sin as lawlessness (anomia), transgression (parabasis), trespass (paraptoma), and unrighteousness (adikia) — together showing sin as both falling short and crossing the line.
