How do we know the doctrine of Christ as our shepherd is true?

Jesus identifies Himself as the good shepherd in John 10:11, stating, 'The good shepherd giveth his life for the sheep.' This declaration underscores His commitment to care for and protect His flock. The affirmation is further supported by passages like 1 Peter 5:4, where He is referred to as the chief shepherd. Additionally, the truth of this doctrine is evidenced in believers' experiences of His guidance, provision, and ultimately, their peace, as they trust Him for their righteousness and salvation. The assurance of His presence among His sheep, as described in Psalm 23, reinforces the certainty that He continues to shepherd His people today.
