George Fox emphasizes the importance of living in the life and power of God, which teaches self-denial and keeps believers from strife and deceit. He encourages the faithful to remain in the light, where actions can be judged by the pure spirit, and to cultivate a deep fear of the Lord that leads to love and unity among one another. Fox warns against confusion and actions contrary to the light, urging believers to serve diligently and to wait for the power of God to transform their earthly nature. He reassures them that through faith and the spirit of promise, they can witness the eternal kingdom of God filled with love, joy, and peace. Ultimately, he calls for unity and growth in God's grace as they gather together in His name.
