E.M. Bounds emphasizes the necessity of zeal in the Christian life, arguing that a lack of fervor leads to a diminished representation of God in the church. He contrasts the 'iced' Christianity of modern times with the 'fiery' faith of the past, asserting that true Christian principles must be alive and passionate to have any real impact. Bounds warns that lukewarmness and insincerity are intolerable to God, and that fervency is essential for effective prayer and love. He calls for believers to ignite their hearts with the consuming fire of faith, as only a passionate church can truly reflect God's presence. Ultimately, he urges Christians to embrace a fiery earnestness in their pursuit of heavenly interests.
