Jesus grew in wisdom and he impressed the teachers of the law with his insight when he was only twelve years old. This wisdom and insight was not based upon a reservoir of head-knowledge. He was not impressing people with the facts he had stored up from studying. Instead he was demonstrating insight into life. He had understanding and he grew in this understanding. God wants to use a difficult marriage or a frustrating work environment to teach us something. While he is not the source of these troubles, he is wise enough to know how he can take advantage of trials to refine us and give us wisdom.
