What does it mean that Jesus is the good shepherd?

In John 10:11, Jesus states, 'I am the good shepherd: the good shepherd giveth his life for the sheep.' This passage encapsulates the sacrificial nature of Christ's mission. He does not merely guide His followers but also protects and saves them at the cost of His own life. This is a profound assurance for believers, affirming that Jesus has undertaken their salvation by taking the penalty for their sin upon Himself. Furthermore, as the good shepherd, He ensures that none of His sheep will be lost, aligning with the promises given in John 6:39 and indicating that His authority and love provide the ultimate security for all who belong to Him. Understanding Jesus as the good shepherd encourages believers to trust in His care and guidance throughout their spiritual journey.
