Today’s “rightly dividing the Word” — “Luke warm” is NOT a biblical term to describe a Christian individual who isn’t on fire for God. It’s a term for describing a Christless apostate church with Jesus stuck on the outside–knocking, hoping an individual within will hear Him, open the door, and have one-on-one fellowship with Him, despite the church as a whole being lost.
The term comes from Christ’s words in Revelation 3:
14 “And to the angel of the church in Laodicea write: ‘The words of the Amen, the faithful and true witness, the beginning of God’s creation.
15 “‘I know your works: you are neither cold nor hot. Would that you were either cold or hot! 16 So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. 17 For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked. 18 I counsel you to buy from me gold refined by fire, so that you may be rich, and white garments so that you may clothe yourself and the shame of your nakedness may not be seen, and salve to anoint your eyes, so that you may see. 19 Those whom I love, I reprove and discipline, so be zealous and repent. 20 Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me.
