Be wary of debt
In Romans 13:8 Paul writes “Owe nothing to anyone except to love one another; for he who loves his neighbor has fulfilled the law.” While unfortunately life in the 2000s requires taking out a loan at some point, there is a large difference between getting a loan to buy a house and using credit or a loan to purchase a television. By careful with using credit cards and accruing debt, and consider carefully whether you have the money or not. A good rule of thumb is to not charge something to a card unless you can pay for it. Staying out of debt has a world of good results, including more money for charity, tithing, and your family.
