Overview
Sin originates in the human heart and separates us from God's holiness. Every person inherits a sinful nature from Adam and actively rebels against God's law. Scripture emphasizes that sin is not merely outward behavior but a condition of the soul requiring repentance and God's grace.
Key Scriptures
"Behold, I was brought forth in iniquity, and in sin did my mother conceive me" (Psalm 51:5, ESV). "The LORD abhors...hands that shed innocent blood" (Proverbs 6:16-19, ESV). "If the world hates you, know that it has hated me before it hated you. But I have said these things to you, that when their hour comes you may remember that I told you of them" (John 15:18-22, ESV).
Application
Regularly examine your heart for sin, confess it honestly to God, and trust Christ's forgiveness to transform your desires and actions toward obedience.
