They didn’t ask questions. That’s what always astonishes and terrifies me about this story from Mark. Jesus shows up by the Sea of Galilee, calls out to Simon Peter and Andrew, tells them he’s going to upend their lives and give them a new vocation, then commands them to follow him without a backward glance or a thought for the family fishing business. Mark records no questions asked by either of the fishermen. In the space of one more sentence, Jesus issues the same call to James and John with the same results. In a flash they’re out of the boat and following Jesus.
