Revelation 3:17-18

17Because you say, “I am rich, and have prospered and grown wealthy, and have need of nothing,” and you do not know that you are wretched and miserable and poor and blind and naked [without hope and in great need],

18I counsel you to buy from Me gold that has been heated red hot and refined by fire so that you may become truly rich; and white clothes [representing righteousness] to clothe yourself so that the shame of your nakedness will not be seen; and healing salve to put on your eyes so that you may see.
