Are we a nation of rich fools?

In Luke chapter 12, Jesus said...

Watch out! Be on your guard against all kinds of greed; a man's life does not consist in the abundance of his possessions.... The ground of a certain rich man produced a good crop... He said "...I will tear down my barns and build bigger ones." ... But God said to him, "You fool! This very night your life will be demanded from you." This is how it will be with anyone who stores up things for himself but is not rich toward God... Seek his kingdom... Sell your possessions and give to the poor. Provide purses for yourselves that will not wear out, a treasure in heaven... From everyone who has been given much, much will be demanded.

Wow! Those are some tough words! So why am I still sitting here in my air-conditioned 2350 square feet (I think) house, surrounded by possessions?

Because I'm trying to reconcile those words with these:
- Proverbs 31 - clearly the wise woman makes sure her family is provided for adequately.
- Proverbs 13:22 - A good man leaves an inheritance for his children's children...
- 1 Timothy 5:8 - If anyone does not provide for his relatives, and especially for his immediate family, he has denied the faith and is worse than an unbeliever.

So what do we do with these? Clearly, one can't sell everything, especially as a parent with children to provide for. I think the answer is to try to live with less in every way you can tolerate, remembering that what each person can tolerate is different, and don't judge each other.

For example, one might live with heat and ac settings more uncomfortable than others in order to save money and increase their giving, while another who can't take the heat forgoes the latest fashions. If we stop looking at our money as our own, and actively look for ways to have less and spend less so we can give more, I believe the Lord will help and direct us, and bless us (not necessarily with more money, unless we're truly faithful at giving more, or perhaps as a test, but with more of Himself, which is greater by far.)
