Matthew 12:1–14 presents a stark contrast between the rigid legalism of the Pharisees and true Sabbath-keeping.
Jesus, however, reframes the Sabbath. He is the Lord of the Sabbath, and His disciples are free to act in mercy and do the necessities, even on the Sabbath. This reframing is a far cry from the self-righteous legalism of the Pharisees, who have turned the Sabbath into a burden rather than a blessing.
Jesus, invites us to rest in Him, the ultimate Sabbath rest.
