Mark 6:2
And when the sabbath day was come, he began to teach in the synagogue: and many hearing him were astonished, saying, From whence hath this man these things? and what wisdom is this which is given unto him, that even such mighty works are wrought by his hands?
On the Sabbath day Jesus came into His own country, Nazareth, with His disciples and began to teach in the synagogue. Many who heard Him were astonished at the wisdom given unto Him and asked from whence He had these things and what wisdom this was, and how even such mighty works were wrought by His hands. The mighty works were healings of the sick, done by laying His hands upon them.
The people recognized His wisdom and mighty works, for they had seen His goodness and known of His healing and were charmed by His words, so that at first they welcomed His teaching with joy. Yet from familiarity with His life as the carpenter they took offense and pointed sneeringly at His origin, refusing to accept Him as the Christ and Messiah and refusing to hear Him as a prophet of God. Their rejection turned to violence from which He was divinely protected by angels, and when He later returned they were still unwilling to receive Him.
Because of their unbelief only a few were open to receive His blessing, so He could do there no mighty work save healing a few sick folk, showing that His work was limited in some places. The verse reveals Christ's power to stay disease, shown in the past in a remarkable manner when seemingly hopeless cases were carried through successfully by diligent treatment and earnest prayer in faith to God before institutions existed for the sick; man's necessity is God's opportunity, and the suffering ones today are invited to have faith in Him for healing. With all treatments given to the sick, simple fervent prayer should be offered for the blessing of healing, pointing sufferers to the compassionate Saviour and Advocate in the heavenly courts and His power to forgive and to heal, who will reveal Himself to save and restore through His gracious providence, including in sanitariums, healing the sick who repent and cease to transgress the laws of God and who unite in prayer confessing sin and receiving pardon.
