4:1-20 This parable contained instruction so important, that all capable of hearing were bound to attend to it. There are many things we are concerned to know; and if we understand not the plain truths of the gospel, how shall we learn those more difficult! It will help us to value the privileges we enjoy as disciples of Christ, if we seriously consider the deplorable state of all who have not such privileges. In the great field of the church, the word of God is dispensed to all. Of the many that hear the word of the gospel, but few receive it, so as to bring forth fruit. Many are much affected with the word for the present, who yet receive no abiding benefit. The word does not leave abiding impressions upon the minds of men, because their hearts are not duly disposed to receive it. The devil is very busy about careless hearers, as the fowls of the air go about the seed that lies above ground. Many continue in a barren, false profession, and go down to hell. Impressions that are not deep, will not last. Many do not mind heart-work, without which religion is nothing. Others are hindered from profiting by the word of God, by abundance of the world. And those who have but little of the world, may yet be ruined by indulging the body. God expects and requires fruit from those who enjoy the gospel, a temper of mind and Christian graces daily exercised, Christian duties duly performed. Let us look to the Lord, that by his new-creating grace our hearts may become good ground, and that the good seed of the word may produce in our lives those good words and works which are through Jesus Christ, to the praise and glory of God the Father.See the notes at Matthew 13:18-23. 16. And these are they likewise which are sown on stony ground, &c.—"Immediately" the seed in such a case "springs up"—all the quicker from the shallowness of the soil—"because it has no depth of earth." But the sun, beating on it, as quickly scorches and withers it up, "because it has no root" (Mr 4:6), and "lacks moisture" (Lu 8:6). The great truth here taught is that hearts superficially impressed are apt to receive the truth with readiness, and even with joy (Lu 8:13); but the heat of tribulation or persecution because of the word, or the trials which their new profession brings upon them quickly dries up their relish for the truth, and withers all the hasty promise of fruit which they showed. Such disappointing issues of a faithful and awakening ministry—alas, how frequent are they!Ver. 17. See Poole on "Mark 4:3"

And have no root in themselves,.... The word has no root in their hearts, only in their natural affections: nor is the root of grace in them; there is no heart work, only speculative notions, and flashy affections:

and so endure but for a time: they continue hearers and professors of the Gospel but for a small season; like the Jews, who rejoiced in the ministry of John the Baptist for a while, and then left him:

afterward, when affliction or persecution ariseth for the word's sake, immediately they are offended. As soon as any small degree of trouble comes upon them, and especially when there is a hot persecution of the professors of religion, because of the Gospel they have embraced; such hearers are stumbled at these things, and cannot bear the loss of any thing, or endure any thing severe for the sake of the word they have professed a pleasure in; and therefore, rather than suffer, they relinquish at once their profession of it.

And have no root in themselves, and so endure but for a time: afterward, when affliction or persecution ariseth for the word's sake, immediately they are offended.
