11 Now the parable is this: The seed is the word of God. 12 The ones along the path are those who have heard; then the devil comes and takes away the word from their hearts, that they may not believe and be saved. 13 And the ones on the rock are those who, when they hear the word, receive it with joy; but these have no root, they believe for a while and in time of temptation fall away. 14 And as for what fell among the thorns, they are those who hear, but as they go on their way they are choked by the cares and riches and pleasures of life, and their fruit does not mature. 15 And as for that in the good soil, they are those who, hearing the word, hold it fast in an honest and good heart, and bring forth fruit with patience.
16 "No one after lighting a lamp covers it with a vessel, or puts it under a bed, but puts it on a stand, that those who enter may see the light. 17 For nothing is hid that shall not be made manifest, nor anything secret that shall not be known and come to light. 18 Take heed then how you hear; for to him who has will more be given, and from him who has not, even what he thinks that he has will be taken away."
Matthew Henry's Commentary on Luke 8:11-18

(Read Luke 8:4-21)
There are many very needful and excellent rules and cautions for hearing the word, in the parable of the sower, and the application of it. Happy are we, and for ever indebted to free grace, if the same thing that is a parable to others, with which they are only amused, is a plain truth to us, by which we are taught and governed. We ought to take heed of the things that will hinder our profiting by the word we hear; to take heed lest we hear carelessly and slightly, lest we entertain prejudices against the word we hear; and to take heed to our spirits after we have heard the word, lest we lose what we have gained. The gifts we have, will be continued to us or not, as we use them for the glory of God, and the good of our brethren. Nor is it enough not to hold the truth in unrighteousness; we should desire to hold forth the word of life, and to shine, giving light to all around. Great encouragement is given to those who prove themselves faithful hearers of the word, by being doers of the work. Christ owns them as his relations.
