While I could probably write a lengthy bit about our family and what we do to maintain fiscal responsibility, instead I'd like to focus on why He wants us to have fiscal responsibility. Even now he has an eternal home prepared for us. He also has a role for us to serve in eternity. He expects responsibility, and trusts us to follow through in the life eternal he grants us. So, we must prove to him in our mortal lives that we are worthy of our eternal gifts. If we manage our family finances with grace and without worry, then the larger eternal gifts and responsibilities that await us will surely bring Him a smile when we receive and manage them properly.
One of the most important aspects of achieving personal fiscal liberty lies in having the ability to support others who are unable to support themselves. Only when our own family finances are in order and responsibly managed can we afford to give to others without fear. Tonight my wife wrote a sizable check for a Good cause, one that I know He would be happy to see us donating towards. If we didn't take care of our financial gifts properly, there's no way this would be possible. I've heard of families with incomes double or triple ours, yet unable to give due to squandering their financial gains. I won't call it wealth, because the truly wealthy are those that respect what they have been given by Our Lord (in my opinion).
Now, this isn't to say that my family is "financially perfect" with our responsibility. However, I can say we strive very hard to take care of our financial independence and growth. We truly see debt as four letter word to be avoided. Credit is a close second, and must be treated with great respect when used, because credit really is just another fancy word for debt, at least if we buy things we cannot pay for in cash.
I thank God that my wife and I are on the same page about having a family budget, and about just about every aspect of managing that budget. As our financial wealth continues to grow (God willing), I hope that we can use our finances to help His purpose in our lives evident.
I ask God only for the wisdom to continue to grow our finances for His glory.
