C.H. Spurgeon emphasizes the consistent and powerful work of the Holy Spirit in the church, likening it to predictable seasonal winds. He asserts that the Spirit is particularly active during times of fervent prayer and when the truth of the Gospel is faithfully preached. Spurgeon highlights that the Holy Spirit responds to genuine prayer and the proclamation of Christ's crucifixion, making the Word effective in the hearts of believers. He warns that any deviation from the truth can hinder the Spirit's work, while a spirit of prayerfulness indicates the Spirit's presence among God's people. Ultimately, Spurgeon encourages believers to engage in prayer and uphold the truth to witness the Spirit's transformative power.
