Those Who Are Rich, Part 3

"highminded" -- literally, "to be lofty in mind", haughty in demeanor, thought, and action.  Albert Barnes notes that haughtiness is for the rich

"One of the evils to which they are particularly exposed. The idea is, that they should not value themselves on account of their wealth, or look down with pride and arrogance on their inferiors. They should not suppose that they are any better people or any nearer heaven, because they are wealthy. Property really makes no distinction in the great things that pertain to character and salvation, It does not necessarily make one wise, or learned, or great, or good. In all these things, the man who has not wealth may be vastly the superior of him who has; and for so slight and unimportant a distinction as gold can confer, no man should be proud."

"uncertain riches" -- literally, "the uncertainty of riches".  Here Paul echoes Proverbs 23:4-5 (NKJV), "Do not overwork to be rich; because of your own understanding, cease!  Will you set your eyes on that which is not?  For riches certainly make themselves wings; they fly away like an eagle toward heaven."  How clearly many in the U.S. have been reminded of the fleeting nature of prosperity over the past three years!
