A man sows seed and does not trouble any further about it—cannot indeed do anything to help it, but he knows that after a definite time the glorious harvest which arises out of the seed will stand before him. By what power is that effected?
An extremely minute grain of mustard seed is planted in the earth and there necessarily arises out of it a great bush, which cannot certainly have been contained in the grain of seed. How was that?
What the parables emphasise is, therefore, so to speak, the in itself negative, inadequate, character of the initial fact, upon which, as by a miracle, there follows in the appointed time, through the power of God, some great thing. They lay stress not upon the natural, but upon the miraculous character of such occurrences.
But what is the initial fact of the parables? It is the sowing.
It is not said that by the man who sows the seed Jesus means Himself. The man has no importance. In the parable of the mustard seed he is not even mentioned. All that is asserted is that the initial fact is already present, as certainly present as the time of the sowing is past at the moment when Jesus speaks. That being so, the Kingdom of God must follow as certainly as harvest follows seed-sowing. As a man believes in the harvest, without being able to explain it, simply because the seed has been sown; so with the same absolute confidence he may believe in the Kingdom of God.
And the initial fact which is symbolised? Jesus can only mean a fact which was actually in existence—the movement of repentance evoked by the Baptist and now intensified by His own preaching. That necessarily involves the bringing in of the Kingdom by the power of God; as man's sowing necessitates the giving of the harvest by the same Infinite Power. Any one who knows this sees with different eyes the corn growing in the fields [pg 355] and the harvest ripening, for he sees the one fact in the other, and awaits along with the earthly harvest the heavenly, the revelation of the Kingdom of God.
If we look into the thought more closely we see that the coming of the Kingdom of God is not only symbolically or analogically, but also really and temporally connected with the harvest. The harvest ripening upon earth is the last! With it comes also the Kingdom of God which brings in the new age. When the reapers are sent into the fields, the Lord in Heaven will cause His harvest to be reaped by the holy angels.
If the three parables of Mark iv. contain the mystery of the Kingdom of God, and are therefore capable of being summed up in a single formula, this can be nothing else than the joyful exhortation: “Ye who have eyes to see, read, in the harvest which is ripening upon earth, what is being prepared in heaven!” The eager eschatological hope was to regard the natural process as the last of its kind, and to see in it a special significance in view of the event of which it was to give the signal.
The analogical and temporal parallelism becomes complete if we assume that the movement initiated by the Baptist began in the spring, and notice that Jesus, according to Matt. ix. 37 and 38, before sending out the disciples to make a speedy proclamation of the nearness of the Kingdom of God, uttered the remarkable saying about the rich harvest. It seems like a final expression of the thought contained in the parables about the seed and its promise, and finds its most natural explanation in the supposition that the harvest was actually at hand.
Whatever may be thought of this attempt to divine historically the secret of the Kingdom of God, there is one thing that cannot be got away from, viz. that the initial fact to which Jesus points, under the figure of the sowing, is somehow or other connected with the eschatological preaching of repentance, which had been begun by the Baptist.
