“The Psalter is of all books of the Bible that book which gives expression to the experimental side of religion. In the law and the prophetic writings, it is God who speaks to his people; but in the Psalter we listen to the saints speaking to God. Hence the Psalter has been at all times that part of Scripture to which believers have most readily turned and upon which they have chiefly depended for the nourishment of the inner religious life of the heart.” — Geerhardus Vos, “Songs From the Soul” in Grace and Glory (1922, 1994), p. 169
