First step to being debt free is to make a budget and stick to it. The first step to fixing credit is to run a credit report and start trying to make things right with any outstanding balances. God does and will bless us, but he also expects us to be responsible with our money and pay what we owe. Improving credit usually takes years of hard work and discipline and not something that can be done to rapidly buy a house. God bless.
My mom would only take as much cash as she could spend each month after paying bills and buy nothing with credit or even debit cards but cash only. That includes gas, food, clothes, etc.
Assessing the difference between wants and needs help.
Only thing you really need is to seek God. He will give you food, shelter and clothes.
Maybe not your own house but some place that keeps you warm.
Maybe not lobster and steak at a fancy restaurant, but enough food to live.
Maybe not prada or name brand clothes but enough to keep us warm.
What we need is so much less than what we want.
When we start putting God first and learning what He wants then the rest falls into place.
