Answer Details
The lesson of the parable of the seed growing secretly is that the kingdom of God grows independent of the will of men. In the parable, a man scatters seeds and they grow without his knowledge or intervention. Similarly, the kingdom of God grows on its own, without human effort or intervention. This teaches that it is not up to humans to determine the growth and success of the kingdom of God, but rather it is a divine process that occurs on its own.
