I believe that he has given such instruction through his prophets in the past. It would be unwise not to watch for financial direction from his appointed servants in the future.

That said, I don't have any reservations about "responsible" debt. I don't consider it contrary to church teachings to invest savings in stocks instead of paying down the mortgage sooner. If that were the case the vast majority of us would be sinning by contributing to a 401K before we have our homes paid off.

Generally, God does not condemn debt. Debt played a large role in the restoration of the Gospel and in financing the Lord's church for well over 100 years. If debt is "evil" then does that mean the Church wasn't divinely led until 50 years ago? Debt is often a necessary tool for us to accomplish many of the mandates he gives us, especially the raising and providing for a family.

The vast majority of talks on debt really boil down to warnings against excessive consumption. We are instructed to live within our means. I interpret that as appreciably adding to my net worth most months long term until retirement. Incurring debt at every opportunity to finance expensive vacations and expensive hobbies is wrong. Incurring debt to engage in faith-based activities, for example starting a business, is risky, but not wrong.
