I look at it like this... Proverbs 27:17 As iron sharpens iron, so one person sharpens another. Solomon compares how we should interact together as iron being sharpened. That is a contentious process! There will be some friction, there will be some heat, but the end result is a sharper more refined blade. I have not seen where gideon has called EVERYONE as individuals lukewarm, but I have seen him refer to the church as such. Such a broad statement should not be taken personally. If for instance you attended a place of worship that was losing membership because there were divisions among the body. Worship was lacking, and the preaching was not quite there, such a statement "lukewarm" could apply to that church but certainly not to you. I have seen churches like this, so certainly it could apply to the universal church. Statistics prove how lukewarm the church is. With 1/3 of the world's population claiming Christ as Savior, there should be very little fighting and social injustice, and yet it is EVERYWHERE. We in the Church can't even get along with each other! How can a body do anything productive if it doesn't agree with itself? If the eyes say, I want to do this, but the mouth says no I'm going to do this, and still the arms declare, no it must be this way, what kind of productivity can such a state bring? None. Look at what Jesus says of the lukewarm church:
Revelation 3:14-22 ESV
14And to the angel of the church in Laodicea write: The words of the Amen, the faithful and true witness, the beginning of Gods creation. 15I know your works: you are neither cold nor hot. Would that you were either cold or hot! 16So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. 17For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked. 18I 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. 19Those whom I love, I reprove and discipline, so be zealous and repent. 20Behold, 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. 21The 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. 22He who has an ear, let him hear what the Spirit says to the churches.
The church that Jesus Himself called lukewarm considered themselves rich, prosperous, in need of nothing, and yet the Lord knew that they were wretched, pitiable, poor, blind and naked. What a despicable state to be in! Having the ability to fix themselves all along and yet being blind to the fact they needed fixing. And yet unlike the other churches Jesus does not say a single individual in this church was outside of this label. He merely states that those who would conquer MUST buy for themselves garments of white and REPENT... gideon is not speaking a biblically unsound message, if anything he is merely echoing what Jesus Himself has said. There has been MUCH debate over whether or not the churches of Revelation were literal ages, or just literal churches or both, but if Jesus called even one church lukewarm there is no reason to believe He wouldn't consider the entire church as such. And it comes down to facts once again, with so many claiming Christ as Savior, there is no need for all the social injustice and fighting that happens on the planet and yet it is there.
The true Church of Christ will rise up though, and will overcome for it has been decreed that those who love the Lord will walk with Him in righteousness and holiness! He will not come for a bride that is not prepared for the wedding! He will prepare us and He will redeem us from the troubles of the world, for He is coming again! Lift your eyes towards the Heavens, for the day of redemption is drawing nigh! Hallelujah and Glory, honor and praise be to the One who loves us and has redeemed us from our sins by His very own precious blood! Jesus You alone are worthy Oh Lord! May we be found in You! May we be found in You Jesus!
