With all the attention given to the presidential primaries around the country, I just found a very helpful article on the Desiring God website by Jon Bloom. Whereas one cannot always predict the presence of wisdom, the book of Proverbs gives keen insights into the presence of foolishness.
The article is weakened in its initial impact by posting it with a picture of one of the presidential candidates before any text giving the wrong impression that the article is a commentary only on Donald Trump.
In reality, the content of the article can be applied equally across the slates of candidates in both major political parties. Further, the characterizations of foolishness from Proverbs have no particular reference to politics, but represent humanity at large in all of its variations!
Read and enjoy the challenge to think well before choosing leaders in any context!
