How do we know that the Good Shepherd is true?

Jesus declares in John 10 that He is the Good Shepherd who lays down His life for the sheep. This act of self-sacrifice demonstrates His genuine care and commitment to those whom the Father has given Him. Unlike bad shepherds who seek personal gain, the Good Shepherd prioritizes the welfare of His flock. He promises that His sheep will never perish and that no one can pluck them out of His hand, providing a strong assurance of eternal security based on His unwavering love and faithfulness.
