How do we know Jesus is the Great Shepherd?

In John 10, Jesus explicitly states, 'I am the good shepherd' (John 10:11), highlighting His unique role in caring for His sheep. This title emphasizes not only His authority but also His sacrificial love, as He lays down His life for them. Furthermore, Hebrews 13:20 refers to Him as 'that great Shepherd of the sheep,' reaffirming His eternal covenant and the hope that comes from His resurrection. This underscores the belief in His sovereign care and provision for believers throughout their lives.
