Why is Christ described as the Good Shepherd?

In Isaiah 40:11, God is depicted as a shepherd who compassionately tends to His flock, which finds its ultimate fulfillment in the person of Jesus Christ. This imagery conveys not only care and guidance but also the redemptive work of Christ, who laid down His life for His sheep (John 10:11). The Good Shepherd seeks out the lost and carries them to safety, fulfilling God’s promise of care and provision. In this way, Christians are assured of Christ's unending support and guidance throughout their spiritual journey, culminating in their eternal security.
