There are two parts of the Gospel
The first is the book of Signs Ch 1-12. "These are the signs Jesus did." John does not use the word "miracles". He sees all the actions of Jesus as signs of his divinity. Water into wine, the Holy Spirit, the woman at the well, the blind man and the bread of life, even the raising of Lazarus are signs.
The second part of the Gospel
The last discourse at the Last Supper. John does not tell the story of the Last Supper. That was well-known. John tells us the great actions and prayers of Jesus, the washing of the feet and his prayer for unity. Today we hear Jesus' prayer at the table of the Last Supper. The new Covenant has a new Commandment; love one another as I have loved you.
