Psalm 13

Vindication. That is what each of us want from those who speak against us. But it is an elusive goal. In our pursuit we tend to go too far and demand revenge rather than hold back for vindication. When David wrote this psalm his complaint focused on God's apparent inactivity. He saw God doing nothing. There were no changes in his situation so the temptation was that God is not active. But David closes by speaking his faith. He expects God to act, and in spite of the circumstances he begins the process of waiting on God to act.
