The problem with lukewarm is that it is neither cold nor hot, thus, useless. And God says in Revelation 3:16, because you are neither hot nor cold. I have no use for you and will spew you out of my month. The water, which is a form of Church, is under spiritual invasions, and the enemies have sown venomous objects in causing irregularity in the water, and it malfunctioned. This irregularity caused the water to malfunction and stop in the middle of process of becoming hot. During the TRANSFORMATION between cold and hot, the water got stuch at lukewarm. This lukewarm posture is most deadly because it send out a false message saying "hot" when, in fact, it's not truly hot. Notice who the Lord is speaking to--- the church. Let's go inside this remarkable study.
