Neville draws on the opening chapter of Paul's letter to the Romans — 'the invisible things of God are clearly seen, being understood by the things that are made' — to argue that this teaching, though addressed to the letter's original recipients some 2,000 years earlier, is meant for everyone who reads it. He uses it to introduce a practical demonstration of imaginal 'traveling' between two remembered places (San Francisco and Los Angeles) as a way of relating visible surroundings to the unseen, causative reality of imagination.
