What are you doing but using human reasoning? What do you think discernment is? We are not angels, but creatures of flesh and blood.
If you are saved, you have received the spirit which is of God; that we may know the things that are freely given to us of God." 1 Cor. 2:12.
The natural man (the unsaved man) uses human reasoning for his discernment. "But the natural man receiveth NOT the things of the Spirit of God: for they are FOOLISHNESS unto him: neither can he know them, because they are spiritually discerned." 1 Cor. 2:14.
