The soil is soft, deep, and clean. The seed sinks, roots, germinates, has light and air, and brings forth ripened grain. The honest and good heart' in which it lodges has been well characterised as one whose aim is noble, and who is generously devoted to his aim' (Bruce, The Parabolic Teaching of Christ, p. 33). Such a soul Christ recognises as possible, prior to the entrance into it of the word. There are dispositions which prepare for the reception of the truth. But not only the previous disposition, but the subsequent attitude to the word spoken, is emphasised by our Lord. They having heard the word, hold it fast.' Docilely received, it is steadily retained, or held with a firm grip, whoever and whatever may seek to pluck it from mind or heart.
Further, not only tenacity of grasp, but patient perseverance of effort after the fruit of Christian character, is needed. There must be perseverance in the face of obstacles within and without, if there is to be fruitfulness. The emblem of growth does not suffice to describe the process of Christian progress. The blade becomes the ear, and the ear the full corn, without effort. But the Christian disciple has to fight and resist, and doggedly to keep on in a course from which many things would withdraw him. The nobler the result, the sorer the process. Corn grows; character is built up as the result, first of worthily receiving the good seed, and then of patient labour and much self-suppression.
These different types of character are capable of being changed. The path may be broken up, the rock blasted and removed, the thorns stubbed up. We make ourselves fit or unfit to receive the seed and bear fruit. Christ would not have spoken the parable if He had not hoped thereby to make some of His hearers who belonged to the three defective classes into members of the fourth. No natural, unalterable incapacity bars any from welcoming the word, housing it in his heart, and bringing forth fruit with patience.
