Luke 8:13

13 `And those upon the rock: They who, when they may hear, with joy do receive the word, and these have no root, who for a time believe, and in time of temptation fall away.

Luke 8:13 Meaning and Commentary

Luke 8:13

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.

Luke 8:13 In-Context

11 `And this is the simile: The seed is the word of God,
12 and those beside the way are those hearing, then cometh the Devil, and taketh up the word from their heart, lest having believed, they may be saved.
13 `And those upon the rock: They who, when they may hear, with joy do receive the word, and these have no root, who for a time believe, and in time of temptation fall away.
14 `And that which fell to the thorns: These are they who have heard, and going forth, through anxieties, and riches, and pleasures of life, are choked, and bear not to completion.
15 `And that in the good ground: These are they, who in an upright and good heart, having heard the word, do retain [it], and bear fruit in continuance.
