John 21 - NIV Foundation Study Bible
21:4 the disciples did not realize. Perhaps the apostles did not recognize Jesus because they were preoccupied with their work, as Mary Magdalene had been with her sorrow (20:14). In addition, there was not much light at this time of day.
21:7 Peter . . . jumped into the water. John was the first to recognize the Lord; Peter was the first to act.
21:17 you know that I love you. Peter denied the Lord at least three times. Here, he affirmed his love for the third time.
21:20–21 the disciple whom Jesus loved. This is commonly considered to be John, the author of this Gospel.
21:24 This is the disciple. This is basically John’s signature to his Gospel.
21:25 Jesus did many other things as well. The Gospel of John is truthful (v. 24), but it is not exhaustive.
