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.
