“To the angel of the church in Laodicea write:
These are the words of the Amen, the faithful and true witness, the ruler of God’s creation. 15 I know yourdeeds, that you are neither cold nor hot. I wish you were either one or the other! 16 So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth. (Revelation 3:14-15)
This church probably thought that it was “good enough.” It probably had pretty good doctrine and gave some money to the poor and sometimes evangelized to the lost. But it also probably tolerated sin and selfishness in the congregation. Jesus warned that since they were lukewarm, that he would “spit you out of my mouth.” He was probably comparing them to a dish of food that was undercooked. They thought that they were pleasing to Him because they did just enough good deeds, when in reality He was offended that they consistently chose to tolerate some evil as well. They did not give Him their undivided service.
