12:9-13 Christ shows that works of mercy are lawful and proper to be done on the Lord's day. There are more ways of doing well upon sabbath days, than by the duties of worship: attending the sick, relieving the poor, helping those who need speedy relief, teaching the young to care for their souls; these are doing good: and these must be done from love and charity, with humility and self-denial, and shall be accepted, Ge 4:7. This, like other cures which Christ wrought, had a spiritual meaning. By nature our hands are withered, and we are unable of ourselves to do any thing that is good. Christ only, by the power of his grace, cures us; he heals the withered hand by putting life into the dead soul, works in us both to will and to do: for, with the command, there is a promise of grace given by the word.
13. Then saith he to the man, Stretch forth thine hand. And he stretched it forth—the power to obey going forth with the word of command.
and it was restored whole, like as the other—The poor man, having faith in this wonderful Healer—which no doubt the whole scene would singularly help to strengthen—disregarded the proud and venomous Pharisees, and thus gloriously put them to shame.
