There are few certainties in life and one of them is that we will have economic uncertainty.  As a matter of fact, if you look at history, you will see that not a year goes by that there wasn't something to be worried about.  Just in this decade, we've had the following:

2000 - Tech bubble bursts in March, 2000

2001 - World Trade Center attacks on 9/11.

2002 - Enron, Arthur Andersen, Tyco, Qwest, Global Crossing, ImClone, and Adelphia-- hiding debt and misrepresenting earnings

2003 - War waged by the U.S. and Britain against Iraq begins; North Korea withdraws from treaty on the nonproliferation of nuclear weapons

2004 - Spain rocked by terrorist attacks; UN Atomic Energy Agency tells Iran to stop enriching uranium

2005 - Hurricane Katrina; Rising interest rates  

2006 - Political corruption scandals; Interest rates rise; Housing market starts to slump

2007 - Housing market meltdown  

2008 - Credit crisis hits financial sector, oil prices drastically rise  

I went back to 1900 and can basically find at least three "scary" events each year that add to that year's uncertainty.  There is a lot of fear out there right now which is no different than any time in history.  So the question is, how do we respond in difficult economic times?  If you apply Biblical principles in your finances, the answer is the same for both the good and bad economic times.  I have found that there are five basic principles that you can apply that work in any economic environment.

Spend less that you earn 

In the house of the wise are stores of choice food and oil, but a foolish man devours all he has. Proverbs 21:20 (NIV)

This is the foundation of every financial plan.  You can have wonderful saving and investing plans, but if you don't have extra money, they won't do you any good.

Avoid the use of debt 

The rich rule over the poor, and the borrower is servant to the lender.  Proverbs 22:7 (NIV)

The people I have been talking to recently that are struggling financially are the ones who got themselves into debt before the economy began to struggle.  When times were good, they failed to save and simply borrowed more money simply because they could.  Those that aren't buried in debt are barely effected by the economic downturn.  

Save money for provisional purpose

Go to the ant, you sluggard; consider its ways and be wise!  It has no commander, no overseer or ruler, yet it stores its provisions in summer and gathers its food at harvest.  Proverbs 6:6 (NIV). 

We know that the economy goes through cycles.  Like the ants, we need to store up in the times of harvest.  This way, when the "winter" comes it's much easier to get by. 

Set long-term goals

I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.  Philippians 3:14 (NIV) 

In his heart a man plans his course, but the LORD determines his steps.  Proverbs 16:9 (NIV)  

I'm sure you've been counseled at some point in your life to set goals; financial goals are no exception.   It's been said before that if you don't know where you're going, any road will take you there.  When we fail to set financial goals, the road to financial freedom is made more difficult.  It's important to remember, that when you do set your goals, God must be at the center.
