What are Christian and Faithful willing to buy at Vanity Fair? What does this suggest about their values?

Christian and Faithful entered Vanity Fair and were immediately recognized as outsiders by their speech, dress, and behavior. They were offered many valuable goods that were on display at the Fair, but Christian and Faithful refused to even look at them. They were not willing to buy anything. This shows that they were not tempted by riches or material possessions. There was nothing there that could add to their happiness. This shows that their attention was on Heaven and Christ. The only goods they desired were spiritual goods, whatever could increase their faith. They were willingly to buy only Truth. The falseness of material goods was not in any way a part of the Truth. Where their treasure was, there was their heart, and their treasure was in Heaven.
