C.T. Studd passionately addresses the concept of true heroism in Christianity, contrasting it with the notion of 'Chocolate Soldiers'—those who are soft and cowardly in their faith. He emphasizes that every true Christian is called to be a soldier of Christ, willing to face hardships and dangers for the sake of the Gospel. Studd illustrates this with biblical examples of heroes like Noah, Abraham, Moses, David, and Paul, who exemplified courage and obedience to God. He challenges believers to reject complacency and embrace the call to action, urging them to restore the lost chord of heroism in their lives and communities. The sermon serves as a rallying cry for Christians to step out in faith and fulfill their divine mission.
