What does the Bible say about Christ bearing the sins of many?

According to Hebrews 9:28, Christ was once offered to bear the sins of many, meaning that His sacrificial death paid the full penalty for the sins of the elect. Before His first coming, the old covenant relied on the repeated animal sacrifices, which could not take away sins (Hebrews 10:4). In contrast, Christ's one-time offering accomplished what the law could not, as He bore the iniquities of His people and redeemed them from their sins (Isaiah 53:6). This act ensures that those who believe in Him are forgiven and justified before God.
