How do we know Jesus is the true Shepherd?

The validation of Jesus as the true Shepherd comes from His alignment with Old Testament prophecies and His miraculous works. In John 10, He speaks of entering through the door, which symbolizes His fulfillment of God's Word as expressed through the Scriptures. The miracles He performed, such as healing the blind man, serve as evidence of His authority and divine nature. Followers of Christ are assured that, as the Good Shepherd, He not only meets their physical needs but also offers them spiritual sustenance. The Holy Spirit, depicted as the porter, opens the door for His sheep to recognize the truth of Jesus, leading them to follow Him faithfully.
