What does the Bible say about Christ's purpose for His people?

In John 17, Jesus states that the Father sent Him to accomplish a purpose, that purpose being the salvation of His people. He affirmed His mission by saying, 'I have glorified thee on the earth; I have finished the work which thou gavest me to do.' This emphasizes that Christ's work on the cross was not just a mere act of sacrifice but the fulfillment of God's plan for redemption. As a result, those who believe are offered eternal life, demonstrating that Christ’s mission was to ensure that all who the Father gave Him can be with Him and behold His glory forever.
