The Lord healed a man on the Sabbath, which the Jews found unacceptable. Although the Law of Moses established the Sabbath as a day of rest for the Jewish nation, Jewish writers added a list of forbidden actions. Through time, the extra-biblical list became more important than the concept of resting from work. It became a burden instead of a blessing. The Lord Jesus explained that His Father is continuously working, and He is also working. Although God rested after creation, meaning He rested on the cosmological arena, He continued blessing His people. Moreover, the Lord implied that, like the Father, He is above the Sabbath.
