Barnes New Testament Notes

Verse 13. And he said, Stretch forth thine hand. This was a remarkable commandment. The man might have said that he had no strength; that it was a thing which he could not do. Yet, being commanded, it was his duty to obey. He did so, and was healed. So the sinner; it is his duty to obey whatever God commands. He will give strength to those who attempt to do his will. It is not right to plead, when God commands us to do a thing, that we have no strength. God will give us strength, if there is a disposition to obey. At the same time, however, this passage should not be applied to the sinner, as if it proved that he has no more strength or ability than the man who had the withered hand. It proves no such thing. It has no reference to any such case. And it should not be used as if it proved any such thing. It may be used to prove that man should instantly obey the commands of God, without pausing to examine the question about his ability, and especially without saying that he can do nothing. What would the Saviour have said to this man, if he had objected that he could not stretch out his hand?

It was restored whole, Christ had before claimed Divine authority and power, Mt 13:6-9. He now showed that he possessed it. By his own power he healed him; thus evincing, by a miracle, that his claim of being Lord of the Sabbath was well founded.

These two cases determine what may be done on the Sabbath. The one was a case of necessity; the other of mercy. The example of the Saviour, and his explanations, show that these are a part of the proper duties of that holy day. Beyond an honest and conscientious discharge of these two duties, men may not devote the Sabbath to any secular purpose. If they do, they do it at their peril. They go beyond what his authority authorizes them to do. They do what he claimed the special right of doing, as being Lord of the Sabbath. They usurp his place; and act and legislate where God only has a right to act and legislate. Men may as well trample down any other law of the Bible, as that respecting the Sabbath.
