Alas, this Oracle has died. Her name was Helen Velonis. Actually, it's probably best to just call her a prophet (or prophetess) because everyone else calls her that. She had her ministry headquarters in tiny Lyle, MN. It was even closer to Iowa than Albert Lea, where I spent my teen years. I went to her church a few times. Once, I went to find an answer about which college God wanted me to go to. I told her that I had a question for God, though I didn't tell her the question. She told me the answer.
This is the only encounter I can point to and say "I witnessed a miracle that betrays science and statistics". Of course, everyone can point to "the song of a bird", "the birth of a child", "that neighborhood boy surviving childhood" as miracles. Sure, I can attest to that as well. But this seemed more unique, more personal.
Her Church (I think it was an elder) also tried to teach me to speak in tongues. I was not ready for it at all. I've never recovered from the confusion that began there. To this day I shrug my shoulders at the notion, neither denying it, nor affirming that I have such an ability.
I guess, in the end, I look back and see a net positive.
Rest in peace, Helen. Rest well in the arms of the one who saved you.
