“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. 21 The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne. 22 He who has an ear, let him hear what the Spirit says to the churches.’”
Rev 3:20 is often taken out of context to be the evangelistic test to invite Jesus into one’s heart.
The context was actually Jesus talking about the church at Laodicea. It was a wealthy and “successful” church (in her own eyes), but only Jesus was not attending it. Rather Jesus saw her as poor, wretched and pitiable. Today, she represents the cheap or hyper grace church all over the world. She fits exactly the description of the Laodicean church. Jesus called the Laodicean church then to be zealous and repent, and is doing likewise to the hyper grace church today.
Our Lord is calling such a church to repent so it is not surprising that the hyper grace false teachers preached against repentance and told their followers not to confess their sins. So if anyone in that church is willing to hear the voice of our Lord Jesus pleading for him or her to repent and open the door to welcome Him, He will come and dine with him or her just like He did with Zacchaeus. Rev 3:20.
