In this chapter, J. I. Packer emphasizes that love is fundamental to Christian ethics and identity. He highlights that Christian love is a response to God's prior love for us. As 1 John 4:19 states, "We love because He first loved us." This divine love is not based on the worthiness of its recipients but flows from God's gracious nature. Similarly, Christians are called to extend love to others, including enemies, without expecting anything in return, reflecting the self-giving love of God (Luke 6:35).
