One Sabbath, Jesus healed a man with a withered hand. The Pharisees, however, hypocritically castigated Him for doing so. Christ's response reveals their problem.
When Jesus healed the man with the withered hand, He was closely watched by the Pharisees, yet He did not hesitate to heal on the Sabbath.
God gave the Sabbath to His people so they can know Him intimately. Idolatry, scattering, and captivity are the natural consequences of Sabbath-breaking.
In the Gospels, questions about the Sabbath center on how to keep it, not whether it should be kept. The way Jesus approached the Sabbath gives us an example.
The Sabbath reminds us that God is Creator and that we were once in slavery to sin. The Sabbath is a time of blessing, deliverance, liberty, and redemption.
