The Gospel of John, as a whole, was written as an evangelistic treatise to persuade people to believe in Jesus for eternal life. The apostle John was an eyewitness to the life, death, burial, and resurrection of Jesus. Like other eyewitness accounts (Matthew, Mark, and Luke), John documented the historical events of the Messiah. John states the purpose for his Gospel, saying, “Therefore many other signs Jesus also performed in the presence of the disciples, which are not written in this book; but these have been written so that you may believe that Jesus is the Christ, the Son of God; and that by believing you may have life in His name” (John 20:31). What John recorded is historically accurate and sufficient to lead someone to believe in Jesus as the Christ, the Son of God and, by believing in Him, to receive eternal life. That’s good news!
