Revelation 3:18-19

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.

19Those whom I [dearly and tenderly] love, I rebuke and discipline [showing them their faults and instructing them]; so be enthusiastic and repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will].
