In a chapter 7 bankruptcy, the debtor turns over all non-exempt property to the bankruptcy trustee who then converts it to cash for distribution to the creditors. The debtor receives a discharge of all dischargeable debts usually within four months. Once that is complete, all debts are considered "discharged" and there is no need to make any additional payments.
There are certain types of loans that cannot be discharged in a bankruptcy (e.g. student loans). If there is anything non-dischargable, thsoe payments will have to continue as if the bankruptcy never even happened.
If a court determines that continuing income may allow a debtor to pay debts in the future, then it would require bankruptcy under Chapter 13 rather than Chapter 7.
