(13) In time of temptation.--The form of the temptation (or better, trial) is explained by the "tribulation or persecution" of the other two reports. So St. Luke gives "fall away" where the others give "they are offended."

Verse 13. - They on the rock are they, which, when they hear, receive the Word with joy; and these have no root, which for a while believe, and in time of temptation fall away. These represent natures at once impressionable and excitable; impulsive men and women who, charmed with the beauty, perhaps (to them) the novelty, of the gospel message, receive the Word, take up the Master's yoke with joy, but without thought. These hastily make a religious profession, but they forget altogether to count what the real cost of such a profession amounts to. Upon these superficial but kindly natures come trouble, perplexity, discouragement, perhaps persecution; then quickly the once-loved religion withers away like corn growing on rocky places beneath the burning summer sun. John Mark, the would-be missionary companion of Paul and Barnabas, was one of this impulsive but little-enduring class; and Demas, once the friend of Paul, but who loved too well the present world. Another instance would be the man who offered to follow Jesus "whithersoever thou goest," as he phrased it, till he found, by the Lord's grave answer, that the Master he offered to follow had neither home nor resting-place; then he seems quickly to have turned back.

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.They on the rock are they, which when they hear,.... The seed that fell upon the rock, or stony ground, signify such sort of hearers,

who receive the word with joy. The Ethiopic version reads, "with joy of heart". But, this sort of hearers receive not the word into their hearts, or with their hearts believe it, and from their hearts obey it, only into their heads; and have only, an historical faith of it; nor with hearty, spiritual, solid joy, or joy in the Holy Ghost: for their hearts remain like a rock, unbroken by the word; but with a flash of natural affection, which quickly goes off.

And these have no root; neither "in themselves", as the other evangelists say, they have no true grace in them; nor have they any root in Christ, nor in the love of God:

which for a while believe: their faith is a temporary one, like that of Simon Magus; which shows it is not true faith; for that is an abiding grace, Christ, who is the author, is the finisher of it, and prays for it, that it fail not. The Persic version renders it, "in the time of hearing they have faith"; and such sort of hearers there are, who, whilst they are hearing, assent to what they hear, but when they are gone, either forget it, or, falling into bad company, are prevailed upon to doubt of it, and disbelieve it. The Arabic version renders it, "they believe for a small time"; their faith do not continue long, nor their profession of it, both are soon dropped:

and in the time of temptation fall away: "or go back", as the Vulgate Latin version, they draw back unto perdition; or "forsake that", as the Arabic version reads, the word, they have heard, and received, their faith in it, and profession of it: "and soon become apostates", as the Persic version renders it. By "the time of temptation", is not meant any particular and sore temptation of Satan, but a time of affliction and persecution, as appears from the other evangelists; which is a trying time to professors of religion, and when those who have not the root of the matter in them, fall away.
