Charles Spurgeon Commentary Mark 1:31

"and he came and took her by the hand, and raised her up; and the fever left her, and she ministered unto them." — Mark 1:31 (ASV)

And he came and took her by the hand, and lifted her up; and immediately the fever left her, and she ministered unto them.

Jesus was very calm; He was not afraid of catching the fever. See how deliberately, and with what solemn, kindly dignity He deals with this sick woman: "He came and took her by the hand." I think I see Him doing it; "and lifted her up." He gently raises her, and she yields to His tender, uplifting hand, and suddenly finds herself cooled of the burning fever and perfectly restored to health and strength. So she rises from her bed, and the first thing she does is to minister to them.

I am sure that, whenever the Lord helps any of His people out of their temporal or spiritual distresses, they feel at once that they must say, What shall we render unto the Lord for all His benefits toward us? Her ministering to them proved that the fever was quite gone, and gone in a way in which it does not ordinarily go; for, as you all know, fever usually leaves behind it extreme weakness.

It seems to burn up the strength that is in a person; and after it is gone, a person is not fit even to wait at table for a long while. But Peter's wife's mother, immediately when the fever was gone, rose and "ministered unto them." Christ's cures are always complete. If He saves us from the burning fever, He saves us from the weakness that follows it. When He deals with soul maladies, His cures are equally complete; there are no after-effects to the soul as there are in many diseases that afflict the body. When the great Physician restores the soul, He restores it completely.
