Isn't it amazing that these fishermen would "at once" drop their nets and follow Jesus? What was it-- his magnetism? His charisma? Did he have them in a trance? Did he offer them a lot of money? Most likely, Peter and Andrew knew about Jesus. They knew him not as a savior, but as a rabbi. In that day, the rabbi was the rock star. The rabbi was the position in society most coveted and respected. And for a rabbi to say "follow me" was a tremendous honor. It meant you were receiving an invitation to apprentice to become one yourself. Fishermen weren't typically qualified to follow a rabbi. So I can imagine these two thinking, "this is our shot-- let's take it now!" If you want to hear more about this, check out Nooma's video titled "Dust".
