From the additional notes to Charles Spurgeon's The Treasury of David, Psalm 116, verse 5.
Gracious is the Lord, and righteous; yea, our God is merciful.
He is gracious in hearing, he is "righteous" in judging, he is "merciful" in pardoning, and how, then, can I doubt of his will to help me? He is righteous to reward according to deserts; he is gracious to reward above deserts; yea, he is merciful to reward without deserts; and how, then, can I doubt of his will to help me? He is gracious, and this shows his bounty; he is righteous, and this shows his justice; yea, he is merciful, and this shows his love; and how, then, can I doubt of his will to help me? If he were not gracious I could not hope he would hear me; if he were not righteous, I could not depend upon his promise; if he were not merciful, I could not expect his pardon; but now that he is gracious and righteous and merciful too, how can I doubt of his will to help me?
In 1639 [Baker] began a series of pious meditations on the Psalms. The first book of the series bore the title of 'Meditations and Disquisitions upon the Seven Psalmes of David, commonly called the Penitentiall Psalmes, 1639.' It was dedicated to Mary, countess of Dorset, and to it were appended meditations 'upon the three last psalmes of David,' with a separate dedication to the Earl of Manchester. In 1640 there appeared a similar treatise 'upon seven consolatorie psalmes of David, namely, the 23, the 27, the 30, the 34, the 84, the 103, the 116,' with a dedication to Lord Craven, who is there thanked by the author for 'the remission of a great debt.' The last work in the series, 'Upon the First Psalme of David,' was also issued in 1640, with a dedication to Lord Coventry. (These meditations on the Psalms were collected and edited with an introduction by Dr. A. B. Grosart in 1882.)
