Revelation 3:16

The divine disgust at lukewarm religion. Christ, says the prophet, is sick of the lukewarm: as the purpose (μέλλω) of rejection does not exclude the possibility of a change upon the part of the church which shall render the execution of the purpose needless, advice to repent immediately follows upon the threat. The latter is unconditional only in form. Exclusion from God's life forms one side of the penalty, humiliating exposure before men the other (18).
