The CONCERN (3:15-17)
I know your deeds (know = full and complete knowledge); Finding nothing in their deeds to commend them for the Lord moved on to His concerns regarding this church
They were neither cold, not hot, but lukewarm (this was understood by the citizens because due to having to travel miles in the aqueduct, the water arrived lukewarm (not hot for a bath or cold for drink)
Hot = those who are spiritually alive and vibrant
Cold = those who have rejected Jesus and the Gospel
Lukewarm = not saved but not openly rejecting Christ (fakes as si seen in Matthew 7:22-23)
This church which is full of fakes who pretend to know God but in truth do not, make the Lord sick (I would rather you hot or cold)
You say that you are rich and have need of nothing but you are wretched, miserable, poor, blind and naked = they were rich in spiritual pride but bankrupt in saving grace
