From Tim Chester's wonderful book on progressive sanctification, a kind of John Owen for dummies!
In Greek mythology, the Sirens would sing enchanting songs, drawing sailors irresistibly towards the rocks and certain shipwreck. Odysseus filled his crews ears with wax and had them tie him to the mast. This is like the approach of legalism. We bind ourselves up with laws and disciplines in a vain attempt to resist temptation. Orpheus, on the other hand, played such beautiful music on his harp that his sailors ignored the seductions of the Siren song. This is the way of faith. The grace of the gospel sings a far more glorious song than the enticements of sin, if only we had the faith to hear its music. (You Can Change, 64, Tim Chester)
