it is like a grain of mustard-seed, which when sown in the earth, is less than any other grain that is sown there.

Again, he said, the state of the gospel is like that of the grain, which a man sows in his land:

however he takes his repose by night, or is employ'd by day, the grain shoots up and grows without his inspection.

for the earth spontaneously produces, first the blade, then the ear, after that the grain of corn in the ear.
