Here is an except from Margaret's vision if anyone's interested:
"...now look out for the sign of the Son of man.
Here I was made to stop and cry out, 0 it is not known what the sign of the Son of man is; the people of God think they are waiting, but they know not what it is. I felt this needed to be revealed, and that there was great darkness and error about it; but suddenly what it was burst upon me with a glorious light I saw it was just the Lord himself descending from Heaven with a shout, just the glorified man. even Jesus; but that all must, as Stephen was, be filled with the Holy Ghost, that they might look up, and see the brightness of the Father's glory. I saw the error to be, that men think that it will be something seen by the natural eye; but 'tis spiritual discernment that is needed, the eye of God in his people.
... be filled with the Spirit."
