"So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth." (Revelation 3:16) Few warnings in Scripture ring with such dreadful weight as this: Christ himself rejecting those who bear his name yet lack the fire of true devotion. In *Lukewarmness in Religion*, Henry Wilkinson, a scholar of the highest order and a preacher of piercing conviction, unfolds this solemn truth with unmatched precision. He lays bare the tragedy of spiritual indifference, showing how a half-hearted faith is more offensive to God than outright unbelief. With careful exegesis, Wilkinson traces the warnings of Christ to the church of Laodicea, pressing upon the reader the urgent necessity of true zeal, sincerity, and unwavering obedience. But this work is not merely a warning-it is a call to the life Christ has called his own to live. With the full weight of Scripture, Wilkinson exhorts believers to cast off complacency, to shake free of dead formalism, and to lay hold of Christ with the earnestness of those who see eternity at the door. He does not merely expose the danger; he shows the path to a faith that is burning, steadfast, and pleasing to the Lord. Included in this edition is Wilkinson's masterful sermon on the Antichrist, added as a a powerful appendix in which he unpacks Paul's warning in 2 Thessalonians 2:3-10, revealing the rise, reign, and ruin of that Wicked One. With clarity and force, he lays out the marks of the Man of Sin, exposing the deception and judgment that follows those who receive not the love of the truth. Here is a work that cuts through all pretense, calling men and women to true and living faith. May the warning be heeded, and may Christ be glorified.
