You, who are Truth, reside everywhere to answer all who ask counsel of You, and in one act reply to all though all seek counsel upon different matters. And You answer clearly, but all do not hear clearly. All ask what they wish, but do not always hear the answer that they wish. That man is Your best servant who is not so much concerned to hear from You what he wills as to will what he hears from You.
–Augustine, Confessions, Book 10.26.37.
That last sentence is especially wonderful, until I consider the implications for longer than 10 seconds.
