How do we know Christ's role as the Good Shepherd is true?

The title 'Good Shepherd' found in John 10 signifies Christ's willingness to sacrifice Himself for the sake of His flock. Jesus states that He lays down His life for the sheep, demonstrating His deep love and commitment to their salvation. In His sacrificial death, He fulfills the requirements of justice, provides atonement for sin, and establishes a relationship with His people that cannot be broken. This truth is foundational to the Christian faith as it assures believers of His relentless care, guidance, and provision throughout their lives.
