Verse 21. Oh that men would praise the Lord for his goodness, and for his wonderful works to the children of men. It is marvellous that men can be restored from sickness and yet refuse to bless the Lord. It would seem impossible that they should forget such great mercy, for we should expect to see both themselves and the friends to whom they are restored uniting in a lifelong act of thanksgiving. Yet when ten are healed it is seldom that more than one returns to give glory to God. Alas, where are the nine? When a spiritual cure is wrought by the great Physician, praise is one of the surest signs of renewed health. A mind rescued from the disease of sin and the weary pains of conviction, must and will adore Jehovah Rophi, the healing God: yet it were well if there were a thousand times as much even of this.
