I probably know and believe in what the Bible teaches as well as you. IF married people(husband and wife) are in a “monogamous, faithful marriage”, there is very little possibility of either partner getting AIDS. I guess in your world, spouses have never cheated on each other. ;0)
I thought I was in a monogamous marriage and I was proven to be a fool.
You were NOT proven to be anything beyond Faithful. Certainly not a fool.
