36:31 God is calling for men who are willing to leave their farms, their business, if need be their families, to become missionaries for Him. And the call will be answered. In the past there have been men who, stirred by the love of Christ and the needs of the lost, have left the comforts of home and the society of friends, even that of wife and children, to go into foreign lands, among idolaters and savages, to proclaim the message of mercy. Many in the attempt have lost their lives, but others have been raised up to carry on the work. Thus step by step the cause of Christ has progressed, and the seed sown in sorrow has yielded a bountiful harvest. The knowledge of God has been widely extended and the banner of the cross planted in heathen lands.
