George Fox emphasizes the importance of avoiding the vain fashions of the world, urging believers to focus on modesty and sobriety in their appearance and lifestyle. He warns that chasing after worldly trends can lead one away from a solid life in unity with God, and encourages a life that prioritizes spiritual over material concerns. Fox calls for a rejection of the spirit of the world, advocating for a focus on the hidden man of the heart and the eternal riches found in God. He reminds the faithful to live as pilgrims and strangers, valuing their heavenly inheritance over earthly possessions.
