Isaiah 55:10 - For just as the rain comes down / And the snow from heaven, / And does not return there, / Until it waters the earth / And makes it bear and sprout forth, / That it may give seed to the sower and bread to the eater;
55:11 - So will My word be which goes forth from My mouth; / It will not return to Me vainly, / But it will accomplish what I delight in, / And it will prosper in the matter to which I have sent it.
2 Corinthians 9:10 - Now He who bountifully supplies seed to the sower and bread for food will supply and multiply your seed and cause the fruits of your righteousness to increase.
Grain is a seed that undergoes a process to become not only the life giving element to be sown into the earth for increase, but it is also the element that is able to become as food as bread is food. So God's word is seed as the word of His mouth gives us life as well as waters this life and nourishes us with.
God as the Word went through the process of making Himself a man with the life of God within Him,
so that He could be such a seed of life.
He was God's seed.
He was born as the seed of woman.
He grew as a seed.
He lived a human life as such a seed for 33 and 1/2 years as a seed.
He was called the Bread of Life.
He was the Living Bread.
He was the Bread that came down out of Heaven.
He was the Meal Offering.
He died as a grain of wheat,
He resurrected and became a life-giving spirit in His resurrection.
As such a resurrected seed He came to sow Himself as life into us the soil.
His word is planted into our hearts.
His word is water to cause us to grow.
For His multiplication and His increase.
For His harvest.
He also came that man would eat Him as the Bread of Life.
That man would live by Him and not by teachings.
That every word would have a place in man's heart.
That man would have the element of God worked into His being.
That man would have God as the element of His living.
That man would be His many grains, His duplication and increase.
That food would be plentiful on the earth.
