“And he said, So is the kingdom of God, as if a man should cast seed into the ground;”
King James Version (KJV)
4:26 So is the kingdom of God - The inward kingdom is like seed which a man casts into the ground - This a preacher of the Gospel casts into the heart. And he sleeps and rises night and day - That is, he has it continually in his thoughts. Meantime it springs and grows up he knows not how - Even he that sowed it cannot explain how it grows. For as the earth by a curious kind of mechanism, which the greatest philosophers cannot comprehend, does as it were spontaneously bring forth first the blade, then the ear, then the full corn in the ear: so the soul, in an inexplicable manner, brings forth, first weak graces, then stronger, then full holiness: and all this of itself, as a machine, whose spring of motion is within itself. Yet observe the amazing exactness of the comparison. The earth brings forth no corn (as the soul no holiness) without both the care and toil of man, and the benign influence of heaven.
Mr 4:26 So is the kingdom of God. This parable is given only by Mark, but its general lesson is enforced by parallel passages, e.g. Isa 55:10,11 Jas 5:7,8 1Pe 1:23-25. In the kingdom of grace, as in nature, we are laborers together with God; the results of our work depend on him, and for the perfection of these results he takes his own time (1Co 3:6-9). Hence, (1) it is ours to sow the seed (the truth), his to give it growth; (2) having sown, we are to wait for time and God to perfect it; (3) this he does according to the definite order of development--first the blade, then the ear, then the full corn in the ear; (4) not until there has been time for the development, are we to expect to reap. The lesson is one of trust and hope. Should cast seed. The word of God, the Gospel.
