What is the significance of Christ laying down His life for His sheep?

In John 10:14-15, Jesus states, 'I am the good shepherd and know my sheep... I lay down my life for the sheep.' This act of laying down His life is a central theme of the Gospel and signifies the depth of Christ's love for His chosen ones. It reassures believers that their salvation is secure because Christ died specifically for them. His death was not in vain; it was intentional and effective for those He came to save. This assures us that we can trust in His sacrifice, as He gives eternal life to His sheep, as seen in John 10:28, where He declares, 'They shall never perish.'
