Mark Futato:
One thing is clear when you look at God’s revelation, from Genesis to Revelation, that whenever really big things happen in the history of redemption, there’s music, there’s poetry - for example, when the Man meets the Woman for the first time in the Garden of Eden we have the first poem; at the time of the Exodus we have poetry; during the height of King David’s reign we have poetry; when Christ comes we have poetry; at the end of the Book of Revelation we have poetry, we have music. And I think part of the reason for this is that God not only wants to engage our minds and our wills but he wants to capture our emotions as well - and music and poetry have a way of capturing the heart, they have a way of capturing the mind, they capture the will, they capture the emotions, they capture the intellect. And so I believe that God has put a lot of his revelation, for example the whole book of Psalms, in musical poetic form because it captures the whole person.
