Every Christian who would abound in prayer and piety ought, in all reason, to make the Psalter his manual; and, moreover, it were well if every Christian so used it and were so expert in it as to have it word for word by heart, and could have it even in his heart as often as he chanced to be called to speak or act, that he might be able to draw forth or employ some sentence out of it, by way of a proverb. For indeed the truth is, that everything that a pious heart can desire to ask in prayer, it here finds Psalms and words to match, so aptly and sweetly, that no man—no, nor all the men in the world—shall be able to devise forms of words so good and devout. Moreover, the Psalter doth minister such instruction and comfort in the act of supplication; and the Lord’s Prayer doth so run through it, and it through the Lord’s Prayer, that the one helpeth us finely to understand the other, and the two together make a pleasant harmony …

In my opinion, any man who will but make a trial in earnest of the Psalter and the Lord’s Prayer will very soon bid the other pious prayers adieu, and say, Ah, they have not the sap, the strength, the heart, the fire, that I find in the Psalter; they are too cold, too hard, for my taste!
