By this word I mean a number of things. For example, possessing the ability to choose the most appropriate words and behavior in any given context or circumstance. Those that are ethically sound and are most suited to attaining the desired outcome. And then they walk away and speak of how the righteous is made to suffer or how the evil blankety-blanks resisted their every move. While this certainly can be true in some cases, the wise leader will step back and first re-play the movie of what transpired, critique his words and behavior, and take responsibility for the outcome.
Wise people choose their battles well.
Wisdom understands that if you constantly swim against the current of popular opinion, you will be perceived as an insecure person who needs attention, an arrogant person who sees most everyone else as inferior, or a lunatic who needs to be avoided. None of these perceptions are conducive to attaining one's desired outcomes. The wise Christian politician will seek out ways where he can legitimately join the majority and cultivate the image of camaraderie whenever possible. Wise people choose their battles well. Wisdom requires the politician to seek to understand the times in which we live.
