Dr. Helen Smith explains here why it's unwise to claim the spiritual gift of wisdom. Quoting Thomas Sowell:
"Wisdom is the rarest quality of all–the ability to combine intellect, knowledge, experience, and judgment in a way to produce a coherent understanding…Wisdom requires self-discipline and an understanding of the realities of the world, including the limitations of one’s own experience and of reason itself. The opposite ... of wisdom is foolishness"
"One of the interesting things that Sowell discusses is the tendency for intellectuals to think that because they are brilliant in one area, that they are brilliant in all areas."
I've always enjoyed watching as two or more people interact - each sure of being the smartest person in the room.
I've also noted that sometimes genius IQs lack EQ and/or common sense.
In that fix, something once said of my father (and also about me) applies:
"Often wrong, but never in doubt."
I count it a blessing that throughout my growing years my best friend was smarter than me, and that I was forced to spend my days among people with ample common sense.
Like discernment, wisdom is a spiritual gift best confirmed by others.
