Sin represents a fundamental violation of God's original design for humanity. Created as God's image bearers and breath carriers, we were meant to live in perfect fellowship with Him. However, sin entered when humanity chose rebellion over trust, missing the mark of who God designed us to be. This separation affects all people, earning us death and creating a cycle we cannot break on our own. The good news is that Jesus lived the perfect life we couldn't live and died the death we deserved, offering complete restoration through repentance and faith in His grace.
