Luke 6:10

There was only one answer that the religious leaders could give. It was lawful to do good and unlawful to do evil on the Sabbath. However, they refused to answer because their answer virtually would have given Jesus their approval to heal the man. They did not want to do that because they wanted to retain their traditional abstinence from Sabbath activities. Jesus proceeded to do good and healed the man’s hand, but He did so without performing any physical work. There was nothing the critics could point to as an act that Jesus performed for which they could condemn Him. This method of healing pointed to Jesus being a prophet sent from God at least and to His being God at most.
