Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain.
Here we have a beautiful picture from nature that shares a glorious truth. Suppose we have a single kernel of corn sitting on the table. Come back in a week and it will still be a single kernel of corn. Come back in two weeks and there will be no change. Even after a year, there will still only be one kernel of corn. However, take that kernel of corn and plant it into the ground and, after a matter of days, that single grain will die, but then a miracle takes place. That grain will then come to life and begin to sprout. In a matter of months, that single grain will have gone from a rather insignificant-sized grain to a cornstalk standing six feet tall. On that one stalk will be several ears of corn, each one having perhaps hundreds of kernels. Then talking each one of those new kernels and planting them will result in thousands more grains. It has been said that if such a process could be carried out for a period of one year, there would be enough corn to cover the earth.
Jesus' point is most clear. The key to fruitfulness as seen from God's design in nature is that death to self is necessary for life to come forth. Jesus, of course, set the example by His own death. For each one of us, this same truth applies. We must die to self for that wonderful fruit to come forth.
