David Forsyth examines the characteristics of worldly churches in James 4:1-3. These characteristics include being quarrelsome, which hinders evangelism, and being carnal, driven by frustrated desires for recognition. Forsyth also identifies prayerlessness as a key trait, either failing to seek God’s wisdom or praying with wrong motives. He emphasizes the importance of peace-loving attitudes and sincere prayers for purity among church leaders, warning against self-focused ambition and encouraging believers to guard against worldliness in their congregations.
