What does the Bible say about Jesus as the Great Shepherd?

In Hebrews 13:20-21, Jesus is referred to as 'that great shepherd of the sheep,' illustrating His role in the covenant of grace, where He fulfills all that was required to redeem His people. The Great Shepherd is not only responsible for the salvation of His sheep but also for their preservation, ensuring that none will be lost. This comfort comes from understanding that He seeks His elect and has the power to save them completely, as affirmed in John 10 when He promises eternal life to His sheep.
