The Gospel according to John is one of the most well known books in the Bible. John’s main purpose is found in John 20:31 where he says he has written this book so people will believe that Jesus is the Christ, the Son of God, and that by believing they may have life in His Name. The first 18 verses tell us many wonderful truths about who Jesus is. The main truth communicated is that Jesus Christ shows us who God is. He is the Word, He is God, He is life, He is light, He came and took a human body, and He explains God to us.
