Yes, your secured interest will "ride through" the bankruptcy. However, if the debtor attempts to "unsecure" the claim through some adversarially court action in bankruptcy, then you will need to either defend, or you may lose your secured interest.
If the debtor has listed your debt as a claim, and the claim as listed is satisfactory to you, then you can avoid filing a proof of claim
(by doing so, you would force the court to give you a jury trial if the debtor tries to unsecure the debt). Or, at your option you can file a proof of claim with the bankruptcy court
(and without a lawyer), and while you will give up your right to a jury trial, you will be automatically notified of anything to do with your claim, even if the debt is not scheduled.
A Chapter 7 takes about 120 days to complete. It could take longer or shorter, but four months is pretty typical.
Hope this helps.
