What does John 1:37 mean?

The two disciples referred to in verse 37 are John (the author of this gospel), and Andrew. Ancient writings very rarely used a "first person" style. It was uncommon for a descriptive text to say, "I did this, I said that." Letters were a different form of writing, as seen in Paul's epistles. John is also being modest by not bringing extra attention to himself. Instead, he refers to himself as "the disciple whom Jesus loved," and other terms. John was most likely a young teenager at this time. Though all of the other disciples would be martyred for their faith, John would still be writing to fellow Christians nearly 60 years later. This means John was not only one of the first to follow Jesus as a disciple, but he was also the longest-surviving of the apostles. He was the first to follow Jesus on earth, and the last to follow Jesus into heaven. The fact that John was present for many of the events in Jesus' life is proven by the minute details he offers in his gospel.
