3:18 I advise you: Buy gold purified in fire from me so that you may be rich. Buy white clothes from me. Wear them so that you may keep your shameful, naked body from showing. Buy ointment to put on your eyes so that you may see.
I advise you:
For a church so involved in materialism (apparently from all the wealth of the city), to ask them to "BUY" points an accusing finger at them and says they don't have everything SPIRITUALLY. In fact, they have just enough spiritualism to make them "lukewarm".
Our SIN, unconfessed and unforgiven by the Lord, is our nakedness. Only the white cloth of righteousness can hide our nakedness. After we receive our white clothes, we actually MUST PUT THEM ON!
Ointment for the eyes impedes the "dazzling splendor" of the world's light. The devil can make material things look so good. But, ointment for the eye has another function: that of healing. It opens understanding to the hope of our calling (Ephesians 1:18); it removes the world's blinders (2 Corinthians 4:4-6).
This verse indicates that the lukewarmness of Laodicea is not the laxity of Christians but rather the condition of not really knowing Christ. They may have accepted Him as their Savior BUT they have kept control of their life, i.e. haven't made Him their Lord.
What is your position today? Lukewarm because He isn't the complete Lord and Boss over your life?
