4:31-44 Christ's preaching much affected the people; and a working power went with it to the consciences of men. These miracles showed Christ to be a controller and conqueror of Satan, a healer of diseases. Where Christ gives a new life, in recovery from sickness, it should be a new life, spent more than ever in his service, to his glory. Our business should be to spread abroad Christ's fame in every place, to beseech him in behalf of those diseased in body or mind, and to use our influence in bringing sinners to him, that his hands may be laid upon them for their healing. He cast the devils out of many who were possessed. We were not sent into this world to live to ourselves only, but to glorify God, and to do good in our generation. The people sought him, and came unto him. A desert is no desert, if we are with Christ there. He will continue with us, by his word and Spirit, and extend the same blessings to other nations, till, throughout the earth, the servants and worshippers of Satan are brought to acknowledge him as the Christ, the Son of God, and to find redemption through his blood, even the forgiveness of sins.And they were all amazed,.... The people in the synagogue; they were astonished at his doctrine before, and now at his miracles:

and spake among themselves; as they were in the synagogue,

what a word is this? meaning, either what sort of doctrine is this which is attended with such power and miracles; or what a word of command is this, "hold thy peace, and come out of him?" and so the Ethiopic version renders it, "what is this mandatory", or "commanding word?" to which agrees the Syriac version, rendering it with the following clause thus; "what is this word", that "with authority and power it commands the unclean spirits, and they come out?" See Gill on Mark 1:27.
