An Urgent Call to God's Church Truly, there is nothing so tragic, so hard, and so icy as a fossilized church or Christian. Nothing can keep the Christian warm, fresh, and alive like evangelism. Soul-winning is a safeguard against a dead, barren orthodoxy. That the church's expansion depends upon her evangelism is the testimony of the ages. Failing to save, she cannot survive. A lack of evangelism will ultimately lead to extinction. Renowned Bible teacher Dr. Herbert Lockyer examines the call, the methods, the obstacles, and the challenges of bringing the gospel to a lost and hurting world. When men and women inspired by the Holy Spirit offer their lives for the sake of the Lord Jesus and turn the world upside down, it is the greatest adventure of all time!
