Great question. I would guess that some people will be scared because of the lies that have been and will be told about Jesus during the run up to his return. I had a wonderful, and very surprising spiritual conversion last night with my ex-wife's longtime friend. I had no idea she was so spiritually connected to God. We discussed many topics, one being the remnant and the GC. To my surprise, she claimed to be part of GC, even though she has never been exposed to WT doctrine. She called the 7,000 the remnant, and the GC those saved by grace. Out of the blue she said I was part of the remnant, and I had no response other than to ask where she got this teaching from. She said it's from years of Bible study. She feels completely isolated in that nobody around her shares her beliefs.
My son was there during our discussion, and the trinity came up. She and I were able to get him to admit that Jehovah could exist without Jesus, but not vice versa. He tried to hold his own by arguing some Catholic doctrine, but the Holy Spirit prevented it. I could feel the HS speaking through me and her, and I saw its effect on my son. He ceded points that he never would have otherwise. He accepted that the HS isn't a separate person, but Jehovah's power. I had goosebumps multiple times during this conversation.
Back to your question... why will people run? Because the lies Satan has been planting about Jesus all these years will cause those destined to side with him to see Jesus as the problem, and the reason for the world's dysfunction. They will gleefully round up and murder Christians if allowed. The name of Jesus makes some people physically ill, because they have already chosen to side with Satan. These people knowingly and unknowingly side with Satan by worshipping abortion, LGBTQ and any issue that causes anger.
