How do we know Christ's words are life?

In John 6:63, Jesus claims that His words are spirit and life. This statement is foundational for understanding the transformative power of His teachings. Christ’s teachings go beyond mere information; they are life-giving, capable of instilling spiritual vitality in those who hear and believe them. According to 1 Peter 1:23, believers are born again through the living and enduring Word of God, indicating that spiritual rebirth and sustenance come through Christ's teachings. Thus, faith in His words not only brings assurance but also a new life that is wholly dependent on Him as the source of all spiritual nourishment.
