In Perek 8 of Kohelet, the Chacham and Yirei Elokim get in an argument. Their argument discusses G-d's judgment system. The Yirei Elokim says that there is a system and that man has a partnership with G-d. The Chacham says that there is a system, but it is very flawed. The Yirei Elokim explians what he thinks is the judgment system: If you do good than you will be rewarded in this world and if  you do something bad than you will be punished in this world. It was also stated that when you die you are accountable for all of your sins. The Chacham and Yirei Elokim both have some good points here.
