I am reading about voltage buffer Op Amp configurations and it seems like there is no current through the circuit, specifically the load. So why would you want to get a specific voltage to the load if there is no current? I guess I am just confused by the reasoning why you would use a buffer op amp setup.

There is no current from vS to RL. The op amp, however, is capable of sourcing current from its supply (some models more than others), and it is this current that flows through RL.
