Riches aren't to be desired because that desire can never be satisfied. Think about it. Some of the most miserable people are the wealthiest in the world. I've heard it said before, but I cannot verify with fact, that the highest suicide rate per capita is Beverly Hills, Ca. Truth be told, I actually have to make an effort not to desire riches. I want a bigger house, I want nicer televisions, cars, clothes, etc. I want an iPhone, although I think that one should be Biblical, because it's just good stewardship. The bottom line, my natural bent is to want riches, but I have to make the effort not to obsess over them.
In the same way that riches are not to be desired, neither is poverty. This one may seem a bit funny to you, but to desire poverty can be just as much of a trap as desiring riches, but with differing effects. First of all, there have been people in history who have wanted poverty. Of course, not nearly as many who have desired wealth, but they do exist. The thing about poverty, according to this verse is that is stirs up anger in the hearts of those who suffer by it. They feel that their lives are filled with injustice. Funny how we live in the richest nation in the world, and most other countries don't like us very much. Is it because we are so evil, or because of their poverty, perhaps both?
The funny thing is, this prayer seems so dead on; "Just give me what I actually need", yet I am hesitant to pray that myself. I don't think that I'm a glutton in any way, nor do I have false expectations that I'll ever been wealthy by U.S. standards. However, there are still things that I desire, things that I foolishly believe will make me happier if I have them, but I know those things could never be something that I need. So I hesitate. Dare I say a prayer like this and run the risk of it being answered and never seeing any of those things? Dare I actually trust in the wisdom of this prayer and trust that I won't even think about those things if I actually have what I need? What if the whole world were willing to only have what it needs? I know, someone, somewhere is screaming Communism, but that isn't what any of those people want, so it doesn't count.
Seriously, though, why am I, and so many others, perhaps even you, so afraid to say that prayer and fervently mean it; "Lord, please don't give me too much, lest it corrupt me, nor too little, lest it embitter me, but just give me what I actually need to do Your will in life, and to feel content." What are we afraid of losing, thinking that somehow, a bit of our own happiness will bleed out with it? Is that even the condition with which God will even answer a prayer such as this? If we desire contentment, will not God also allow us pleasures in life, whether they be material goods or not? He is a good God, after all. So what would hold you back from saying such a prayer? Personally, I don't want anything to hold me back from such a prayer. Therefore, I have to find a way to look past the mental barriers that say, "Wait! Before you say that prayer, consider that it might mean losing this thing, or that thing." Who cares? The reality is there isn't anything that I 'want' today that will really matter to me in 10-15 years from now, but I will always want peace, contentment, and God in my life.
