It is really needful that we should have some other songs besides the Psalms of David. It is unreasonable to suppose that the Christian church should for ever, and even in times of her greatest light, in her praises of God and the Lamb, be confined only to the words of the Old Testament, wherein all the greatest and most glorious things of the gospel, that are infinitely the greatest subjects of her praise, are spoken of under a veil, and not so much as the name of our glorious Redeemer ever mentioned, but in some dark figure, or as hid under the name of some type.
