Jamieson-Fausset-Brown Bible Commentary

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!
