How do we know that Christ's teaching on the Sabbath is true?

Jesus' claims about the Sabbath are substantiated through His fulfillment of Old Testament prophecies and laws. As the God-man, He uniquely embodies what the Sabbath represents—rest and relationship with God. In Matthew 12:6, Jesus states, 'But I say unto you that in this place is one greater than the temple,' indicating that His presence transforms the understanding of the Sabbath. His teachings are not merely interpretations but are authoritative due to His divine nature. Furthermore, the accounts of His interactions with the Pharisees show that He fulfills the law by demonstrating mercy and compassion, proving His authority to redefine the Sabbath.
