primary purpose of all revelation is to reveal. If the only intention were to hide, silence would secure that, and the parable were needless. But if the twofold operation is intended, we can understand how mercy and righteous retribution both preside over the use of parables; how the thin veil hides that it may reveal, and how the very obscurity may draw some grosser souls to a longer gaze, and so may lead to a perception of the truth, which, in its purer form, they are neither worthy nor capable of receiving. No doubt, our Lord here announces a very solemn law, which runs through all the divine dealings, 'To him that hath shall be given; and from him that hath not, shall be taken away even that which he hath.' II. We turn to the exposition of the parable of the sower, or rather of the fourfold soils in which he sows the seed. A sentence at the beginning disposes of the personality of the sower, which in Mark's version does not refer exclusively to Christ, but includes all who carry the word to men. The likening of 'the word' to seed needs no explanation. The tiny, living nucleus of force, which is thrown broadcast, and must sink underground in order to grow, which does grow, and comes to light again in a form which fills the whole field where it is sown, and nourishes life as well as supplies material for another sowing, is the truest symbol of the truth in its working on the spirit. The threefold causes of failure are arranged in progressive order. At every stage of growth there are enemies. The first sowing never gets into the ground at all; the second grows a little, but its greenness soon withers; the third has a longer life, and a yet sadder failure, because a nearer approach to fertility. The types of character represented are unreceptive carelessness, emotional facility of acceptance, and earthly-mindedness, scotched, but not killed, by the word. The dangers which assault, but too successfully, the seed are the personal activity of Satan, opposition from without, and conflicting desires within. On all the soils the seed has been sown by hand; for drills are modern inventions; and sowing broadcast is the only right husbandry in Christ's field with Christ's seed. He is a poor workman, and an unfaithful one, who wants to pick his ground. Sow everywhere; 'Thou canst not tell which shall prosper, whether this or that.' The character of the soil is not irrevocably fixed; but the trodden path may be broken up to softness, and the stony heart changed, and the soul filled with cares and lusts be cleared, and any soil may become good ground. So the seed is to be flung out broadcast; and prayer for seed and soil will often turn the weeping sower into the joyous reaper.
