How do we know Jesus is a faithful shepherd?

The metaphor of Jesus as the shepherd is robustly depicted in John 10, where He identifies Himself as the 'good shepherd' who sacrifices His life for His sheep (John 10:11). As the Great Shepherd (Hebrews 13:20), He guides and protects, ensuring that His followers lack nothing essential for their spiritual welfare. Psalms, particularly Psalm 23, encapsulate this notion beautifully, affirming that Jesus provides comfort, guidance, and a safe haven. This imagery is foundational to understanding our relationship with Him and His unwavering commitment to His flock.
