A.W. Tozer emphasizes that while men without God face isolation and despair, true followers of Christ are never alone in their mission. He reassures that every Christian, whether a martyr or a missionary, is accompanied by Jesus, who fulfills His promise to guide and support them. Tozer highlights the importance of surrendering to Christ's lordship and obeying His commands, especially as young people are called to their missionary responsibilities. The assurance of Christ's presence and power empowers believers to go forth and make disciples, knowing they are never forsaken. Ultimately, the message is one of hope and divine companionship in the face of life's challenges.
