Psalms 107:21

If we knew no sin, we should know no sickness. Sinners are fools. They hurt their bodily health by intemperance, and endanger their lives by indulging their appetites. This their way is their folly. The weakness of the body is the effect of sickness. It is by the power and mercy of God that we are recovered from sickness, and it is our duty to be thankful. All Christ's miraculous cures were emblems of his healing diseases of the soul. It is also to be applied to the spiritual cures which the Spirit of grace works. He sends his word, and heals souls; convinces, converts them, makes them holy, and all by the word. Even in common cases of recovery from sickness, God in his providence speaks, and it is done; by his word and Spirit the soul is restored to health and holiness.

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.
