Andrew Murray emphasizes the church's neglect of its divine calling to be a light to the Gentiles, highlighting the need for Christians to live solely for God's glory and the salvation of others. He points out that this neglect is often unintentional, stemming from a lack of awareness of their true calling and the consequences of their disobedience. Murray argues that despite the abundance of scripture, the church fails to grasp the truth because it is often approached through human wisdom rather than the power of the Holy Spirit. He calls for a return to a faith that is rooted in the demonstration of God's power, rather than mere intellectual understanding.

Andrew Murray emphasizes that the church holds the responsibility of continuing Christ's work on earth, empowered by the Holy Spirit. He explains that just as Christ was sent by the Father, the church and its members are called to be witnesses, illuminating the darkness of the world. The Holy Spirit is essential in convicting the world of sin and revealing Christ through believers. Murray calls for the church to be wholly devoted to this mission, embodying the light of Christ to lead others from darkness into light.
