You say, "The Church has to go through the persecution, for the perfection of It." The Blood of Jesus Christ perfects the Bride.
A man who chooses a wife don't put her through a lot of punishment; he's already found grace, too, with her; she has found grace with him. He engages to her. And, if there is anything, he'll keep her from every place to turn her hand. His grace is so great upon them.
And so will it be upon the Bride, and so is it on the Bride. We unworthy creatures, deserving of hell, but His grace holds us through it. Look at how many lost and blind! How many, how many sinners was there in the world, the hour I got saved! God saved me for a purpose; and I'm determined, by His will, to do that purpose. I don't care what anything else goes; I want to do it.
And in the hour when I see all the churches, their great glamour, "and rich, and have need of nothing," they say; and see them, miserable, wretched, blind; then patting you on the shoulders, want you to compromise with them. I was born for a purpose, that's to condemn that thing and to call out. This I do.
