"the poetry of the 16th-century Spanish mystic, St. John of the Cross"

I can honestly say, this is not something I ever endeavored to become. I didn’t believe in God as a personality I could know. In fact, it wasn’t even until last October 15th, 2023 that I ACTUALLY believed God was real and loved me back. And only because he actually came down here and spoke with me, as I challenged him to.
