How do we know Christ is the Good Shepherd?

Christ's identity as the Good Shepherd is explicitly stated in John 10:11, where He declares, 'I am the good shepherd. The good shepherd lays down his life for the sheep.' This self-definition aligns with the prophetic words of Zechariah 13:7, which alludes to the shepherd being smitten. Jesus' reference to this passage during His ministry confirms that He is the shepherd foretold in scripture. He comes not only to lead but to sacrifice Himself for the salvation of His elect, fulfilling the divine mandate of redemption as outlined in God's eternal covenant of grace.
