What does John 21:6 mean?
Early in His earthly ministry, Jesus rode out on a boat with Peter, who had just come up empty after an entire night of fishing. Peter cooperated with a seemingly petty request from Jesus, resulting in a massive haul (Luke 5:3–7). Peter reacted to this in faith (Luke 5:8). More recently, Peter and six other disciples are waiting for Jesus in Galilee (Matthew 28:9–10; John 21:1). They've decided to go fishing once more. This is either out of boredom or to resume the trade (John 21:1–3). This night, like the other, has been a failure. Due to the early light (John 21:4), they don't recognize the person on shore calling out. His question is casual (John 21:5), something like a modern English speaker saying, "you kids didn't catch anything, did you?"What Jesus says is much like His advice in their earlier encounter, and with almost the same results. This is not a chance occurrence, as if they caught only a few fish, or continued with a successful night. If catching fish was simply a question of casting the net a few feet away, these experienced men (John 1:35–42) would have done it already; there's a good chance they already had. Yet now the net is so full they can't pick it up. Peter will once again grasp the significance and immediately react (John 21:7).
