Lord, please loosen Stephanie's grip on that car, so she can see you at work in her life. Right now, she's thinking she's in control of this, not you. Let her see your answer, and give it firmly into her mind and heart that your answer is the best answer for her. Any answer you give is for the good of her/your people and for your glory. Help her grow in you thorough this time. Amen.
Stephanie, I'm not getting hiding the car. If they come to repossess it, they do that because it's their car to take. Hiding it, means you know this. We hide what we know doesn't belong to us.
Other ideas though.
-- "Huge" to you, isn't necessarily "huge" to other people. Ask family, friends, and your church for the money to pay for it. And don't be thinking anyone of those people should give you all the money. Even some of the money is good, if some people just give you a little here and a little there. Don't waste your time asking rich people. It is the poor who understand what a little here and a little there gives.
-- Talk to the car company to see if you can renegotiate the bill. Or to see if they'll let you pay a little now and more as you get it. This may mean paying a little with every paycheck, instead of once a month, but how much do you need that car?
-- Check Freecycle. (No, literally. Google that word and then find out what they do.) Because someone in your area right now might have an old car they don't want to trash. Not likely, but then again, God is the God of "not likely," so it doesn't hurt to ask.
-- Check Volunteers of America. (Again, google that phrase.) They're an organization started to help stranded travelers in the US, but have grown beyond that. One of the things they do is take old cars and sell them. Maybe, (just maybe), they have a working car they can give you. If not give, then sell you for less money than that "huge payment." It will be a clunker. But a working clunker still beats a repossessed car.
-- Start a Go Fund Me page, and then promote it to your friends and family through whatever social media platform you use. (FB, Twitter, whatever. Not here though, because that would count as advertising, and we're not supposed to do that here.)
-- If you're living paycheck to paycheck, then tighten your belt better. No matter what we make, we're supposed to budget within that. And part of that budgeting ought to include tithing and savings. You got down-sized at work or you had to take a job that pays less? Then rework your budget to live with what you have now, not what you used to have. Stop buying coffee on the way to work. Make your own. It's cheaper. No, really. A $150 a month telephone plan is excessive. If you're paying a bundle to play with your phone when you're bored, come up with something new to do. (Libraries loan books for free.) Because "data storage" is a luxury, not a necessity. $200 a month for cable is ridiculously high. Cut out cable all together if you can. (Streaming costs us $10 a month.) Cut it back, if you can't. Did you see the latest Star Wars movie? If you did, you had that much more money that could have gone to the car payment. Did you buy car insurance that lessens, if you have no accidents? Yeah, then you paid too much for your car insurance. And do you still live in the over-sized apartment when you had to down-size your job? Then it's time to look for a place you can afford. If you don't know how to budget, then find someone in your family or church who can teach you how. Worse comes to worse, there are charities out there that teach that for free too. (Gonna have to google that too.)
I don't know what God's answer for you will be, but he will see you thorough this too. And the answer is not to hide that car. If they take it back, that means it belongs to them, not you. That's the thing about loans. We're really renting to pay it off. I did give you options. I hope they work out, but half the stress your having is because your trying to hide something that may not be yours for much longer. Trust the Lord, not your hiding abilities.
