These are some Scriptures which have convinced me that I should not have any debt. If we diligently heed God's commandments, we will be blessed:
Being convicted by the Holy Spirit through the Scriptures, I purposed in my heart to get completely out of debt. I sold as many things as I could sell: my motorcycle, TV, couch, etc., and moved into the cheapest apartment I could find (which turned out to be 8ft by 12ft, just 2 feet longer than a prison cell). It took me about a year and a half to pay off about $45k worth of debt.
I am debt-free now, and it is as if a burden has been lifted off of me. My finances cause me no stress whatsoever (even though I make relatively little money).

And the result of heeding His commandments are given in Deuteronomy 28:12:
