Pre-wrath people represent a very recent philosophy. The earliest writings of Rosenthal espousing this point of view that I can find come from about 1982.
Dr. Renald Showers has written an excellent refutation of this philosophy. That came after Rosenthal spent so much time bashing the Rapture.
I read Rosenthal’s book in the early 80’s right after I left the amill teachings. It had me convinced for a period of time. My biggest revelation came when I asked the Holy Spirit for the truth. What I am loosing now is my approval needs of trying to convince everyone that I am right and needing them to agree with me.
I’m a pre-wrather myself. I have Rosenthal’s book and he came to our church for a conference years ago. But, since none of us can be 100% sure, I just pray we’re ready when it happens, whenever it happens.
