spiritual self-assuredness

Of course you are not such wiseacres as to think or say that you can expound the Scripture without the assistance from the works of divine and learned men who have labored before you in the field of exposition . . . . It seems odd that certain men who talk so much of what the Holy Spirit reveals to themselves, should think so little of what he has revealed to others.
