I fully agree that our intentions need to be as clay.  We certainly have to be flexible and not try to "strong arm" our own will into God's plan.  But I think that we need to have those intentions, otherwise, we may find ourselves wandering and just marking time.  We need to make a conscious decision every day to seek God and His will as opposed to just following our own path.  We are constantly seeking just a little more light to illuminate the next destination.  Every time we pray about a decision, we are asking for a little more light.  I think that all of this is part of living intentionally.  Even submission takes intention.
