Well . . . the Bible is not completely sufficient. If it were there would be no need for people like you. Romans 10:14-15. And I dare say you would be even more effective if you could heal the sick and make yourself understood in multiple languages at the same time.
No, the BIble is sufficient. The job of the Pastor is to expound upon what the Bible says. The measure of any ministry is how faithful they are to the Scripture. II TImothy 3:16-17 says that Scripture equips us for every good work, which means it is sufficient for the soul. A Pastor/Teacher's job is to be as faithful to the Scripture as possible.
It is no good if the BIble is innerant if it is also not sufficient. If you want, I can provide a number of other BIble references, but right now I have to get out a letter to some people.
