Too often intelligent people (and people who think they are intelligent) are arrogant. They take pleasure in thinking that they are better than others. This is, in fact, a problem with the majority of the population in general. The truly smart people on this earth, however, are the ones who do not eschew wisdom in favor of scientific or academic pursuits, but complement their intelligence with Godly wisdom. Unfortunately, though, intelligent people, out of pride, just like many rich people, tend to ignore wisdom and the benefits of humility. I myself have been proudful at times, and I know how easily it can lead to sin and ruin.
When I say pride, I don't mean necessarily in a "I'm king of the world!" kind of way. I also mean the little prideful things that we do and think that involve placing higher interest in ourselves rather than others. Humility, in contrast, is knowing exactly who you are in the eyes of God and in the grand scheme of this universe. People with true humility serve (even in positions of leadership) rather than control. It is something that, sadly, very few politicians of either party possess in this day and age. Leaders who are like Nehemiah and Joshua are what are needed in this country, whether it's leadership in families, the federal government, or any level in between.
