Explanation
John first says that Jesus did many other signs. He also says those signs were done in the presence of his disciples. Yet they are not written in this book. The verse highlights that what readers have in front of them is not everything Jesus did.
02John points to what is written in this bookAfter saying that many signs are not included, John turns to the signs and words that are included.

After saying that many signs are not included, John turns to the signs and words that are included. He contrasts “many other signs” with “these are written”. That contrast keeps attention on the written material in this book and on the reason John gives for it.

04Believing is linked with life in his nameJohn adds a second part to the purpose statement: “and that believing you may have life in his name”.
