How do we know that Jesus is our Good Shepherd?

In John 10, Jesus expressly calls Himself the Good Shepherd, stating that He lays down His life for the sheep. This act of self-sacrifice is the ultimate demonstration of His love and commitment to His followers. The character of a shepherd is to provide, guide, and protect, and Jesus fulfills this role perfectly. He provides us with everything we need spiritually, confirming that 'I shall not want,' as captured in Psalm 23. This realization that Jesus genuinely cares for us and knows us personally gives believers confidence in His protection and guidance, reinforcing the concept that we are His sheep, called to recognize and follow His voice.
