Firstly, it tells us that "if we have food and covering, with these we shall be content" (v8).
Next it tells us that if we are NOT content with these but "want to get rich" we get ourselves into all sorts of trouble: we "fall into temptation and a snare and many foolish and harmful desires which plunge men into ruin and destruction" (v9)
Finally it tells us that if we are already rich we shouldn't be hoarding our riches but rather "be generous and ready to share" (v17-18).
If we are a Christian and not rich, lets not desire to become so.
If we are a Christian and already rich lets be generous with our riches and share.
"A rich man's wealth is his strong city and like a high wall in his own imagination" (Proverbs 18:11)
