The theme of the Gospel of John is that Jesus is the Son of God.
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 believing you may have life in His name.
— John 20:30-31
In our first study of John chapter 1 we went through the seven names of Jesus the Son of God. Here we go over two other lists of “sevens” presented by John in this chapter, seven works and seven witnesses which prove Jesus is the Son of God. John leaves no room for accepting anything less than Jesus being the Son of God not only by the works He performs, but by the witnesses who knew Him personally.
