'The historical books I may compare to the outer courts of the Temple; the Gospels, the Epistles, and the Psalms, bring us into the holy place or the Court of the priests; but the Song of Solomon is the the most holy place: the holy of holies, before which the veil still hangs to many an untaught believer...The Song is a golden casket, of which love is the key rather than learning.'
Charles Spurgeon in Charlie Cleverly, Song of Songs: Exploring the Divine Romance, p.15.
