Scripture clearly states that knowledge, wisdom and understanding are gifts of the Holy Spirit and that not all are blessed with all of the gifts. To whom are those not blessed with the gifts of knowledge, wisdom and understanding to turn or the interpretation of Scripture and how are they to know to whom they must turn?
That contradicts Genesis 1:19 and in particular, the parable of the snake and the fruit. It also contradicts what you previously agreed with, which was that the Holy Spirit would not do one's thinking for them.
