Why is the Son of Man's suffering important for Christians?

The suffering of Jesus, referred to as the Son of Man, is crucial in understanding the nature of His mission. According to Mark 8:31, He must suffer many things, be rejected, and be killed, ultimately rising on the third day. This suffering is not arbitrary; it was ordained by God before the foundation of the world for the redemption of a specific people. His vicarious suffering highlights God's immense love and serves as the foundation for the believers' faith, demonstrating that salvation comes solely through His sacrificial death, as outlined in Ephesians 1:7.
