And he said, So is the kingdom of God, as if a man should cast seed into the ground;…
In saying that the seed groweth up we "know not how," the mysterious nature and working of grace is hinted at. It is not regulated by natural laws, though they afford many illustrative analogies. It cannot be reduced to a science, like agriculture or mechanics. There is no philosophy of the Holy Ghost. Regeneration is not the result of any forces which human reason defines and gauges, much less controls; and the Divine life which is breathed into the soul by the mysterious visitation of the Spirit, blowing like the wind, of which we cannot tell whence it cometh and whither it goeth, is afterwards maintained by supernatural supplies from the same invisible source, and is "hid with Christ in God."
(Josiah D. Smith.)
