The fields are white unto harvest

Labor not for the things that perish, but instead seek to be a servant of God, sowing the seeds of everlasting life and truth.
For the fields are white unto harvest and the laborers are few, very few.

Because the laborers are very few, God has opened the doors and windows of Heaven to enable the few to accomplish the work of many.
In the same way that modern farmers suffering from the lack of laborers no longer use the hand held scythes but instead use big combines to harvest their huge fields; God has enabled the few to accomplish the work of many.

Though being persecuted, oppressed and suffering from the lack of resources and finances; yet God has enabled those very few to reach the whole world.
In their hands rests all the power of the Kingdom of Heaven.
