“Do you think this scripture does not apply to “you” either, since it was written to an angel ?”
That passage in Revelation is NOT what sets the context for a sentence found in 1 Cor 3. That is ALSO basic English and logic. If I want to know what Jesus was referencing when he says “wheat” in a parable, I do not pick up a text on agriculture...
I understand your answer as you do not regard Revelation as applying to you.
