Stop being afraid.
Elijah has come. No, it was not when he was here 5 minutes ago. He was here in the same spirit and power of John the Baptist. When Elijah actually came was not the time when the prophesy was fulfilled From Malachi 4:4-6. It was in John the Baptist as predicted in John 1:21.
And again, uncomfortably, another prediction of Jesus's suffering. This is going to get louder and more frequent. I suppose we'd better get used to it.
