Why are the teachings of Jesus central to Christian faith?

In John 6:68, Simon Peter responds to Jesus' questioning about leaving Him, saying, 'Lord, to whom shall we go? Thou hast the words of eternal life.' This indicates that the teachings of Christ are not only profound but fundamentally life-giving. The Gospel reveals Jesus as the source of truth and life, and His teachings guide believers in their faith and actions. To follow Christ's words is to embrace the very essence of Christian living, providing clarity and purpose to those seeking spiritual nourishment.
