R.A. Torrey shares a powerful account of a prayer meeting at Chicago Avenue Church, where the officers sought the Holy Spirit's convicting power due to a lack of conviction of sin. During his sermon, a man known for his sporting lifestyle unexpectedly accepted Jesus Christ, prompting a wave of responses from the congregation. This moment of conviction led to many individuals, including a troubled colonel, accepting Christ as their Savior. Torrey emphasizes the importance of being open to the Holy Spirit's work in transforming lives and the urgency of responding to God's call. The sermon illustrates the profound impact of the Holy Spirit in bringing conviction and salvation.
