How do we know that Jesus had to suffer for our sins?

The necessity of Christ’s suffering is a foundational doctrine within Christianity, articulated throughout the Scriptures. Jesus Himself stated that He must go to Jerusalem, suffer many things, and be killed before rising again (Matthew 16:21). This prophetic word affirms that His sacrificial death was preordained to fulfill prophecy and to provide atonement for His people. Isaiah 53 beautifully encapsulates the reason for His suffering, revealing that He was wounded for our transgressions and bruised for our iniquities. The assurance that those for whom He died must be saved is encapsulated in Acts 4:12, where it states that there is no other name under heaven by which we must be saved. This highlights both the necessity and sufficiency of Christ’s work for salvation.
