The Kingdom of God

 ²⁶He also said, "This is what the kingdom of God is like. A man scatters seed on the ground.²⁷Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. ²⁸All by itself the soil produces grain—first the stalk, then the head, then the full kernel in the head. ²⁹As soon as the grain is ripe, he puts the sickle to it, because the harvest has come."³⁰Again he said, "What shall we say the kingdom of God is like, or what parable shall we use to describe it? ³¹It is like a mustard seed, which is the smallest seed you plant in the ground. ³²Yet when planted, it grows and becomes the largest of all garden plants, with such big branches that the birds of the air can perch in its shade."

Jesus is the sower and the seed.  Jesus plants and the kingdom of God grows by his Word. Christ' s body and blood are planted and they sprout creating a great harvest of believers.  Jesus does this all for us in our baptism that we may be a part of the harvest of the kingdom of God.
