Yes, you must list all of your debts in your bankruptcy, even debts that are non-dischargeable, secured, or that you wish to pay off in full.
You can voluntarily pay a creditor after you receive a discharge, without becoming legally liable to continue paying. Thus listing a creditor does not prevent you from paying creditors you wish to pay after bankruptcy.
Omitting a debt constitutes perjury which could result in your discharge being denied.
