The letter could in fact be entitled, "God's Wisdom versus Man's Wisdom".
Wow! That was a fantastic overview! To preach Christ and let God take care of the results instead of preaching a message that seems to produce more results in a quicker time. Wow!
You will discover MOST of the problem passages in the gospel letters are of a similar nature as the world's wisdom has been how they have been interpreted for centuries (even millennia)
Keep diggin' bro.
