Taking Responsibility
Power carries responsibility with it, and that responsibility is easy to lose sight of once the power arrives. The kings of ancient Israel ran into this again and again. Hold enough authority and you start to believe you can do whatever you please, because you have the means to actually do it. One king wanted another man's wife, so he arranged to have the husband placed at the front of a battle in a spot where death was almost certain. He bent the circumstances to clear his own path. That was power turned against the very people it was supposed to protect. These kings weren't bound by the law; they wrote it. And the old principle still holds: to whom much is given, much is expected.
Then there is the opposite story. Some people never set out to hold power at all, yet when it landed on them they met the moment well. A measure of humility helps everyone, including the people we consider great. What tends to draw us toward the saintly figures is exactly that they stay humble. Even Jesus made no effort to rule as an earthly king.
So if you find yourself in a position of authority, or with real money at your disposal, keep your head level. Resist doing a thing simply because the chance is now open to you, or because it proves to others that you can and they can't. Wealth and influence are obligations before they are privileges. The more you're able to do, the more gets asked of you.
