In this stirring message, we examine Christ's personal evaluation of the church at Laodicea — a church neither hot nor cold, but tragically lukewarm. Jesus, the Amen and faithful witness, stands as the ultimate authority, accurately diagnosing the spiritual temperature of His people. This sermon outlines the symptoms of a hot church, the symptoms of a cold church, and the sad signs of a lukewarm church — warning us of the dangers of complacency, comfort, and carnal confidence. Christ lovingly counsels the church to return, repent, and rekindle their fire for Him. We will also discover the cure for lukewarmness: abiding in Christ, attending to His Word, assembling faithfully with His people, actively serving, and asking fervently for revival. The Lord is knocking at the door of His church — will we open the door with zeal, or will we be found indifferent? What is the temperature of your heart today? Hot, cold, or lukewarm?
