Is there any point in learning meditation from an unenlightened person?

If a meditation teacher is not enlightened, is there any point in learning from him/her? According to [Satipatthana Sutta](http://www.accesstoinsight.org/lib/authors/soma/wayof.html) , the awakening should usually take some time between 7 days and 7 years. If somebody who devoted his life to teaching meditation still hasn't got enlightened, there must be something wrong with his method, then? Or am I missing something? The question is general, but to give some context: I have been to a meditation retreat using S.N. Goenka's method, and what I learnt seems to have some merits. But if I assumed a Buddhist point of view that the awakening is the ultimate goal, there is no reason to follow his advice, since Goenka has stated that he is not enlightened. Is there any point in using his techniques?
