and do not return to it
without watering the earth
and making it bud and flourish,
so that it yields seed for the sower and bread for the eater,
11 so is my word that goes out from my mouth:
It will not return to me empty,
but will accomplish what I desire
and achieve the purpose for which I sent it. Isaiah 55:10-11(NIV)
Some things happen naturally. The water cycle is a good example: rain and snow fall to the earth and provide moisture for plants that grow and produce a harvest. As the plants use the water, it is released in the form of elements that recombine in the atmosphere to produce rain again. Some of the water flows to streams and rivers and the ocean where it becomes available for fish, or animals, or men. The earth blooms because of the water. Our lives are sustained by the water.
This passage mentions two classes of people who benefit from the rain and snow. First, there are the farmers who get seed as a product of harvest. They can produce another crop with seed. They are provided a resource to continue for another year.
Second, there are eaters, hungry people who need the nutrition provided by the harvest. The rain and snow provide the moisture to grow grain that serves both needs: seed for planting a new crop and grain to grind for bread.
Grain and harvest are symbols used over and over in the Bible. This time they are used as a metaphor for the power of the Word of God. As surely as the rain will produce a harvest of grain, so the Word of God will produce the results he intends. The harvest may be righteousness. People who hear God's word may respond in repentance. The harvest may be in souls that come to a saving knowledge of God through Jesus Christ. Sometimes the harvest is a personal understanding of God in quiet communication. However it comes, the harvest will accomplish his desire and fulfill the purpose for which he sent it.
How has God's Word produced a harvest in your life today?
