In Christian scholarship, the Book of Signs is a name commonly given to the first main section of the Gospel of John, from 1:19 to the end of Chapter 12.
It is named for seven notable events, often called "signs" or "miracles", that it records.
[1] John 20:30 Therefore many other signs Jesus also performed in the presence of the disciples, which are not written in this book; 31 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.
It is this indication by the author of the gospel that the signs are selected, which leads to the examination of them as a sequence of seven.
[5] Anthony T. Selvaggio replaces walking on water with the cleansing of the Temple because John 2:18 includes the word "sign".
