Working with, listening to, and loving people who aren't the usual and familiar suspects is often uncomfortable. Look at Simon. Though momentarily thrilled by the catch, he asked Jesus to go away. He knew that growing his business would mean that he and Andrew and James and John would have to work their butts off. That is always the way when God calls.
Any serious commitment requires that.
Anyone who calls you to that commitment owes you that honest warning. There's a very distinct sense in the translation that we aren't catching people in a net to kill them, or as the church so often does, simply to bore them to death. We are catching them alive. And the implication is that we want to keep them alive. Also there is the word zoos, as in zoology, that is the study of living things.
