Power is a strange thing. From being able to move things to pear pressure to politics. Power is able to free or to suppress.
But what is power exactly. There is a lot to say about power. First it is a form of measurement. Power measures the ability to control your environment. Be it things or people. In the case of social context there are several sources from which power is given or claimed. Bertram Raven argues that there are five bases for power. Think of power given by experience, age or charisma.
There are many examples of power abuse. Religious cults for example or political positions. A well known political philosopher is Machiavelli who describes cunning ways to gain and keep power. He's not afraid to use ethical questionable ways, like deception, to reach his goals.
But what is the best way to handle the power that you have? Well... In my opinion the best way is a Biblical way that is universal applicable. It's the way that Jesus handled power. A well known passage in the New Testament is John 13 where Jesus washes the feet of his disciples. He, as their teacher and master, does the most humble job. Using power by serving.
In my opinion this rule “Power by serving” is the universal applicable rule. A manager of e certain department will e the most successful if she or he serves her or his employees. Serving means doing every bit of work to make sure his employees have the means to do their job and be happy. Parents should serve their children. Politicians must serve the inhabitants of their country. In every level of power using this power to serve others will gain the most for everyone.
