"You say, 'I am rich; I have acquired wealth and do not need a thing.' But you do not realize that you are wretched, pitiful, poor, blind and naked. I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see."
All rich men must humble themselves and unload their camel after hours (by one's latter days) so it can go through the eye of the needle (Jerusalem's night gate), an example of earthly riches having no credit for eternal rank.
But you do not realize that you are wretched, pitiful, poor, blind and naked.
A rich man easily forgets that there is a more important wealth, the wealth of the spirit.
I counsel you to buy from me gold refined in the fire, so you can become rich;
God calls Himself a consuming fire. Gold from the refining fire is wisdom from the Word.
and white clothes to wear,
Good works, planting seeds that we will take with us if we show ourselves approved and wear during the eternity.
so you can cover your shameful nakedness;
God's refining fire teaches one how to erase the rudiments of a person if he/she repents and tries to obtain wisdom.
and salve to put on your eyes, so you can see."
Only by gaining wisdom by reading the Word can one obtain eyes to see.
A good verse. It shows God's high opinion of gold as a store of wealth for our short fleshly existence.
