Conviction
Conviction of sin — the inner persuasion that one has violated God's holiness and stands guilty before him — is presented in Scripture as the essential precondition for repentance and faith. The Psalms record David's experience of conviction: "When I kept silent, my bones wasted away through my groaning all day long... your hand was heavy upon me; my strength was dried up" (Ps. 32:3–4). The acknowledgment of sin brings relief: "I acknowledged my sin to you... and you forgave the iniquity of my sin" (Ps. 32:5). Job's encounter with God moves from confident self-defense to prostrate silence (Job 40:4–5).
The NT identifies the Holy Spirit as the agent of conviction: Jesus promises the Spirit will "convict the world concerning sin and righteousness and judgment" (John 16:8). Peter's Pentecost sermon produced conviction in the hearers: "they were cut to the heart" and cried out "What shall we do?" (Acts 2:37). Paul teaches that the law serves to produce conviction of sin so that sin might be shown to be "sinful beyond measure" (Rom. 7:13) — making the gospel's remedy both necessary and welcome.
