what does the bible say?
Scripture reveals two truths: sin results in death, and a substitute can bear that punishment. Under the Old Testament law, worshipers brought sacrificial animals to die as their substitutes (Leviticus 1:4; Leviticus 17:11). For instance, the Passover lamb demonstrated that judgment was averted for those covered by the lamb’s blood (Exodus 12:1–13). Similarly, during the annual Day of Atonement, two goats were used. One was slain, while the other was set free, carrying away the people's sins. Together, they symbolized both payment and the removal of guilt (Leviticus 16:15–22). Although they were animals, the prophets foreshadowed a human who would bear iniquity (Isaiah 53:4–6).
In the New Testament, Jesus fulfilled this expectation by being the spotless Lamb who offered Himself once for all (John 1:29; 1 Corinthians 5:7; Hebrews 10:1–14). He lived without sin but suffered for sinners to bring them to God (Hebrews 4:15; 1 Peter 3:18). Paul says God presented Christ as a wrath-satisfying sacrifice (Romans 3:24–26). Through the cross and resurrection, debts are canceled and dark powers disarmed (Colossians 2:13–15). Those who trust in His substitutionary sacrifice receive forgiveness, righteousness, and eternal life (John 3:16–18; 2 Corinthians 5:21; Romans 8:1).
