J.C. Ryle emphasizes the need for a return to the evangelical doctrines of the 18th century, arguing that the same truths that once revived England can do so again today. He laments the lack of powerful preachers and the dilution of doctrine among modern ministers, suggesting that the absence of fervor and commitment to the gospel has led to diminished success in ministry. Ryle calls for a bold commitment to evangelical truth, urging believers to work diligently in their own spheres and to pray for a revival of faith and leadership. He believes that with a return to the old ways and the raising up of dedicated men, the church can once again experience significant spiritual victories. Ryle's message is a clarion call for faithfulness to the gospel amidst contemporary challenges.
