Psalm 73:1014

Therefore their people turn to them and drink up waters in abundance. They say, “How would God know? Does the Most High know anything?” This is what the wicked are like—always free of care, they go on amassing wealth. Surely in vain I have kept my heart pure and have washed my hands in innocence. All day long I have been afflicted, and every morning brings new punishments.

What have I gotten out of it? 

The psalmist concludes that a good life has not brought him wealth or freedom from troubles (verse 12) and therefore has been "in vain" (verse 13). But this unmasks his heart. His obedience was not a way of pleasing God but rather a means of getting God to please him. When we sat to God, "I'll serve you only if X happens," then it is X that we love, and God is just a necessary apparatus for obtaining it. The shock of this admission begins to clear his mind. In every difficult circumstance we may hear God saying to us: "Now we will see if you came to me to get me to serve you or so that you could serve me."
