"Listen up, new recruits: Psalms 73 is about how the wicked prosper and the righteous suffer. Asaph, the author, was envious of how the wicked seem to have it all. He was questioning why God seemed to be blessing them and not him. But then he went to the sanctuary and realized the futility of their prosperity, and that God would eventually punish them. So, in the end, the righteous will be rewarded and the wicked will be punished, so it's important to stay faithful to God."
