John Gill emphasizes the significance of brotherly kindness as an essential aspect of godliness, asserting that without it, external worship and religious profession are meaningless. He explains that brotherly kindness is a reflection of true regeneration and is vital for maintaining peace and honor within Christian communities. Furthermore, Gill highlights that charity, or love, extends beyond just fellow believers to encompass all people, including enemies, and is paramount in the Christian faith. He concludes that while faith initiates the journey, love is the ultimate expression of a believer's life.
