A.W. Pink emphasizes the significance of the Gospel as the 'ordained lamp' that illuminates the darkness of the world, highlighting God's promises to His church and the role of Christ as the Anointed One. He explains that the Gospel was established by divine decree, beginning from eternity and shining through the ages, even amidst adversity. Pink illustrates how God sovereignly appoints where, when, and through whom the Gospel is preached, ensuring that His elect hear the message of salvation. He stresses that the effectiveness of the Gospel is not determined by human effort but by God's sovereign will, as He decides the measure of success for each minister. Ultimately, the sermon calls believers to recognize the divine orchestration behind the spread of the Gospel and to trust in God's plan for His church.
