Andrew Murray emphasizes the church's critical mission to proclaim God's love to the world, lamenting the neglect that has led to countless souls perishing without the knowledge of Christ. He highlights the staggering reality of thirty million heathens dying each year, urging Christians to recognize their responsibility in sharing the gospel. Murray asserts that the church was specifically sent to carry God's love to all nations, and the failure to do so stems from selfishness and unfaithfulness. He calls for a renewed commitment to this divine mandate, reminding believers of the urgency and importance of their calling.
