Mark 4:26-29, “And He said, This is what the kingdom of God is like. A man scatters seed on the ground. Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know-how. All by itself, the soil produces grain—first the stalk, then the head, then the full kernel in the head. As soon as the grain is ripe, he puts the sickle to it, because the harvest has come”.
The seed here represents the word of God which is sewn into the receptive soil of an individual’s heart. It then grows mysteriously and completely independent of human effort which never fails to surprise a believer. In the end, the believers get to witness and experience the true spiritual life and the kingdom of Heaven in all its majesty.
