Arno Gaebelein (1861-1945) was an American Methodist minister and Bible commentator. In his classic commentary on the Psalms, he writes,
"The book of Psalms is preeminently a prophetic book. The New Testament warrants us to say this for the quotations from the Psalms are overwhelmingly on prophetic lines. It is not saying too much when we say that all the great prophetic messages of the prophets of God, and their visions concerning the future are wonderfully given by the Psalms and many of them are enlarged. The prophetic scope of the Psalms is truly marvellous. Yet this feature of it is the most neglected in the study of the book. It is rarely ever studied as a prophetic book; the devotional study has always been in the lead."
