John 20:31
But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
John 20:31 (KJV)
Context
John 20:31 closes the Gospel of John with the author’s own statement of purpose. The phrase “these are written” points back to the signs, teachings, and events recorded throughout the book, especially the resurrection account that immediately precedes this verse. John selected these things deliberately, not to give a complete biography, but to lead readers to a specific conclusion about Jesus.
The verse states that purpose in two parts. First, John wrote so that his readers might believe that Jesus is the Christ, the Messiah promised in the Old Testament, and that He is the Son of God, a title that emphasizes His divine nature. Second, John wrote so that believing, his readers might have life through His name. The Gospel presents Jesus as the promised Messiah who fulfills the offices of prophet, priest, and King, and the title “Son of God” points to His unique relationship with the Father.
Meaning
The word “believe” in this verse carries the sense of a deep, personal trust, not merely intellectual agreement. John presents belief as the response that connects a person to the life Jesus offers. This life is not only future eternal life but also a present spiritual life, a restored relationship with God that begins now and continues forever.
The phrase “through his name” is significant. In Scripture, a name represents the person, his character, and his authority. To have life through the name of Jesus means to receive salvation on the basis of who He is and what He has done. The name of Jesus is the channel through which the gift of life is given to those who trust Him.
Biblical connections
John’s purpose statement echoes the broader message of the Gospel. Throughout his account, he records miracles and signs that reveal Jesus’ divine nature and fulfill Old Testament prophecies about the coming Savior. The verse serves as a key text for understanding the purpose of Scripture as a whole, showing that written revelation is given to lead people to faith in Christ.
Application
John’s stated purpose gives direction for how we read his Gospel. The signs and teachings are recorded so that we might believe, and that belief is meant to result in life. Studying the Gospel deepens our understanding of who Jesus is and strengthens our confidence in Him.
The verse also models the heart of evangelism. Just as John wrote to lead people to faith, we are called to share the good news so that others may believe that Jesus is the Christ, the Son of God. The evidence and testimonies in John’s Gospel remain useful for helping people come to faith.
Believing in Jesus brings us into a personal relationship with Him. As we walk in faith and trust in His name, we experience the abundant life He promises, both in this world and for eternity. John 20:31 captures the purpose of the Gospel and the heart of the Christian faith: that Jesus is the Christ, the Son of God, and that believing in Him brings life through His name.
Reflection
John wrote so that we might believe and have life. This verse invites us to examine our own trust in Jesus, not as a one-time decision but as a continuing reliance on Him as Lord and Savior. The life He offers through His name is a gift to be received and enjoyed, and the Gospel record is given so that we may hold firmly to that gift.
