Would someone clarify this section.
"And in addition to your testimony, the testimony of three of my servants, whom I shall call
and ordain, unto whom I will show these things, and they shall go forth with my words that
are given through you.
Yea, they shall know of a surety that these things are true, for from heaven will I declare
it unto them.
I will give them power that they may behold and view these things as they are;
And to none else will I grant this power, to receive this same testimony among this generation,
in this the beginning of the rising up and the coming forth of my church out of the wilderness-
clear as the moon, and fair as the sun, and terrible as an army with banners".
What power did the 3 servants have that the others did not?
