I suppose they'd have to make being part of a flock attractive. I personally wouldn't find being in a flock attractive.
The idea of those who obey God as being sheep of a flock subject to a shepherd is particularly strong in John 10:1-15 and Luke 15:3-7. It seems to recall Psalm 23. I escaped from the flock over 40 years ago, even though I was happy being a sheep at the time. I realised then that I wasn't really a sheep after all, and could find my own way through life, without having to obey any shepherd.
Rather than being lost, I've found myself and gained a greater understanding of the world. And I'm so happy I made that decision as a teenager, even happier than if I'd remained with the flock, because it's given me the kind of happiness that can only come from independence and having a grasp on reality.
My escape from the flock has freed me to embrace what science has to offer, which I consider far more plausible than belief in the supernatural, and is the nearest we can get to the truth about how nature and the universe work. I've felt a sense of freedom ever since, and am happy and at peace with this.
I still have an interest in religions, mythology and related matters, and am fascinated that people still believe in things that to me are plainly just not true. And I now have the humility to admit that I don't know everything; and I prefer that to the pride involved in invoking supernatural beings to mask that.
