David has already pointed out to us the signs (or miracles in the KJV). Here is the list of 7 (a magic number of course; look up ‘seven signs’ in google; you will be amazed. Then look up “seven signs john”):
The concept of signs loomed very big in John. Commentators have selected 7 incidents where Jesus performed a “miracle” (so that people might “believe on him” and have “eternal life”):
1. the Wedding at Cana (Chapter Two)
2. healing of the nobleman’s son (Four)
3. healing of the lame man (Five)
4. feeding of 5000 (Six)
5. walking on water (Six)
6. healing of the blind man (Nine)
7. raising of Lazarus (Eleven)
John wrote these stories to convince people, so they might ‘believe’ and have ‘eternal life’. Once again: this belief was not to a set of intellectual propositions, but as emphasized in the synoptics, a matter of trust in what Jesus said, in the gospel.
Trusting in the truth of Jesus’ words and actions, we commit ourselves to the Way (14:6).
