A.B. Simpson emphasizes that a genuine and vibrant Christian life has the power to attract others to Christ, contrasting it with the lackluster examples of mediocre Christians that fail to inspire. He recounts the story of a prominent citizen who, despite his admirable qualities, lived without Christ until he witnessed a true expression of faith that compelled him to seek a relationship with Jesus. This transformation illustrates that the world is drawn to authentic Christianity, which offers a compelling invitation to a life of complete dedication to God.

T. Austin-Sparks emphasizes the critical importance of Christian unity as a foundational element for effective witness to the world, arguing that disunity undermines the church's mission and credibility. He highlights that true unity is not merely a spiritual concept but must be manifested in practical love and cooperation among believers, as Jesus prayed for in John 17. Sparks warns against superficial approaches to unity that ignore the deeper spiritual realities and stresses the need for a mental revolution among Christians to overcome divisions rooted in spiritual immaturity. He asserts that the glory of Jesus' name should be the unifying force for all believers, guiding their actions and decisions. Ultimately, he calls for a return to the Holy Spirit's lordship to achieve the oneness that Christ desires for His church.
