Mark 4:29

He said, “God’s Kingdom is as if a man should cast seed on the earth,

and should sleep and rise night and day, and the seed should spring up and grow, though he doesn’t know how.

For the earth bears fruit by itself: first the blade, then the ear, then the full grain in the ear.

He said, “How will we liken God’s Kingdom? Or with what parable will we illustrate it?

It’s like a grain of mustard seed, which, when it is sown in the earth, though it is less than all the seeds that are on the earth,

yet when it is sown, grows up and becomes greater than all the herbs, and puts out great branches, so that the birds of the sky can lodge under its shadow.”
