Selection from Apocalypse Explained ~ Emanuel Swedenborg
THE INCREASE OF THE CHURCH WITH MAN IN PARTICULAR, AND WITH MEN IN GENERAL BY THE LORD
Jesus said, So is the kingdom of God as if a man should cast seed upon the earth, and should then sleep and rise night and day, and the seed should spring up and grow up he knoweth not how. For the earth beareth fruit of herself, first the blade, then the ear, then the full corn in the ear. But when the fruit hath come forth straightway he putteth forth the sickle, because the harvest is ready (4:26-29)."The kingdom of God" means the church of the Lord in the heavens and on the earth; and the implantation of it with all who receive truths and goods from the Lord, not from self, is described by these words, every particular of which corresponds to spiritual things and signifies them
"A man casts seed upon the earth, that he then sleeps, and rises night and day, that the seed springs up and grows up he knows not how;" for "seed" signifies the Divine truth, "to cast seed into the earth" signifies the work of man, "to rise day and night" and finally "to put in the sickle" signifies in every state.
The rest signifies the Lord's work; and the "harvest" the implantation of the church in particular and in general:
For it is to be known, that, although the Lord works all things, and man nothing from self, yet He wills that man should work as if from self in all that comes to his perception. For without man's cooperation as if from self there can be no reception of truth and good, thus no implantation and regeneration. For to will is the Lord's gift to man; and because the appearance to man is that this is from self, He gives him to will as if from self.
