Chuck Smith emphasizes the urgent need for laborers in God's work, noting that the lack of intercessors has always hindered the fulfillment of His mission. He reflects on the biblical examples of Isaiah and Ezekiel, who lamented the absence of those willing to stand in the gap for others. Smith challenges the congregation to consider their own commitment to prayer and action for the lost, particularly in nations like China, India, and Russia. He reminds us that while the harvest is plentiful, the workers are few, urging believers to respond to the call to serve. The sermon calls for a deeper awareness of the spiritual needs around us and the importance of stepping up to meet those needs.
