Revelation 3:15-16, 20

‘I know your deeds, that you are neither cold (invigorating, refreshing) nor hot (healing, therapeutic); I wish that you were cold or hot. So because you are lukewarm (spiritually useless), and neither hot nor cold, I will vomit you out of My mouth [rejecting you with disgust].

Behold, I stand at the door [of the church]and continually knock. If anyone hears My voice and opens the door, I will come in and eat with him (restore him), and he with Me.
