Andrew Murray emphasizes that a true missionary revival requires more than just temporary enthusiasm or increased interest; it demands a deep, personal devotion to Christ that remains steadfast amidst changes. He argues that the church needs a new outpouring of the Holy Spirit to inspire genuine dedication and effectiveness in missionary work. Murray highlights that the call for more missionaries can only be met through a collective spiritual awakening and commitment to the Lord's work, akin to a second Pentecost.

Andrew Murray emphasizes that God's heart is dedicated to the salvation of all people, demonstrated through the gift of His Son and Spirit. He encourages believers to become fellow-laborers in God's work, reminding them that His grace is sufficient for every command. Murray believes that a genuine missionary revival is achievable, as God desires to transform the hearts of His children to prioritize the kingdom of Christ. This revival, starting with believers, will lead to a powerful overflow of salvation and service to the unsaved. He calls for earnest prayer and commitment to this mission.
