(Revelation 3:2,15-16 KJV)

(2) Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.

(15) I know thy works, that thou art neither cold nor hot: I would thou we cold or hot.

(16) So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
