Let's agree to disagree. I don't use credit cards. Fraud isn't the only risk. You could lose a job. Or there be some issues with payroll and your paycheck comes late. Or an unexpected bill comes up and the credit card can't be paid off. Or you get injured and can't work for a period of time. Or...
It just isn't a game I play. My opinion is that it is unwise. See Proverbs 22:7
If you hit your thumb with the hammer, it's not the hammer's fault. And congratulations if you have your house paid off and are not a "slave" to a bank or mortgage company. But stop paying your property taxes, and you'll see just how much of a "slave" you are to the state. But hey, Mark 12:17, so it's cool.
