10 and lo, there was a man having the hand withered, and they questioned him, saying, 'Is it lawful to heal on the sabbaths?' that they might accuse him. 11 And he said to them, 'What man shall be of you, who shall have one sheep, and if this may fall on the sabbaths into a ditch, will not lay hold on it and raise 'it'? 12 How much better, therefore, is a man than a sheep?—so that it is lawful on the sabbaths to do good.' 13 Then saith he to the man, 'Stretch forth thy hand,' and he stretched 'it' forth, and it was restored whole as the other.

Commentary on Matthew 12:9-13
(Read Matthew 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, Genesis 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.
