Why is the concept of Christ's sacrifice important for Christians?

The cross stands at the center of Christian belief, representing the culmination of Jesus’ mission to save His people from their sins. As the sermon emphasizes, 'He came to die, because if He didn't die, we won't live.' His sacrificial death not only fulfills the law but also demonstrates God’s love and justice. In Isaiah 53, we see the prophecy of the suffering servant who bears our iniquities. Therefore, understanding Christ’s sacrifice is vital; it reminds believers that their righteousness comes not from their works but through faith in Christ's completed work on the cross. The act of taking up one’s cross, as mentioned by Jesus, signifies a willingness to identify with His suffering and the transformative power of His resurrection.
