Andrew Murray emphasizes the transformative power of a holiness revival, drawing parallels between the evangelistic efforts of Whitefield and Wesley, who sought deliverance from both the guilt and power of sin. He highlights how their experience in the 'Holy Club' led to a profound understanding of faith that claims the fullness of Christ, which in turn fueled their impactful preaching. Murray also acknowledges the contributions of General Booth and the Salvation Army in promoting a message of complete devotion and salvation. Despite doctrinal differences, he notes the undeniable divine endorsement on the fervent desire to preach full salvation and total consecration to Christ.

A holiness revival! What was the great evangelistic revival in England through Whitefield and Wesley but this? They had together at Oxford been members of the "Holy Club". With their whole heart they had sought deliverance from the guilt of sin, but also from the power of sin. When their eyes were opened to see how faith can claim the whole Christ in all fullness, they found the key to the preaching which was so mightily effectual for the salvation of men. What John Wesley did for the Methodism, General Booth, and his disciple, did for the Salvation Army. Looking at the material on which he had to work, it was amazing how, with his teaching of the clean heart and full salvation, he was able to inspire tens of thousands with a true devotion to Christ and the lost. There may be great differences of doctrine, but no one can be blind to the seal God has set upon the intense desire to preach a full salvation and an entire consecration.
