From the Gospel of Matthew 13:23
23 “But he who received seed on the good ground is he who hears the word and understands it, who indeed bears fruit and produces: some a hundredfold, some sixty, some thirty.”
From the work, Arcana Coelestia 3310.2
That the “seed” is the Word of the Lord, thus truth, which is said to be of faith, and that the “good ground” is the good which is of charity, is evident, for it is the good in man that receives the Word; the “hard way” is falsity; a “stony place” is truth that has no root in good; “thorns” are evils.
From the work, Arcana Coelestia 1940.3
 Now unless the rational submits itself to the Lord’s goods and truths, it either suffocates, or rejects, or perverts the things that flow in; and this is still more the case when they flow into the sensuous knowledges of the memory. This is what is meant by seed falling on a highway, or upon a rocky place, or among thorns, as the Lord teaches (Matt. 13:3-7; Mark 4:3-7; Luke 8:5-7). But when the rational submits itself and believes the Lord, that is, His Word, the rational is then like good ground or earth, into which the seed falls and bears much fruit.

The first rational, in the beginning, knows no other love than that of self and the world; and although it hears that heavenly love is altogether of another character, it nevertheless does not comprehend it. But then, when the man does any good, he perceives no other delight from it than that he may seem to himself to merit the favor of another, or may hear himself called a Christian, or may obtain from it the joy of eternal life. The second rational, however, with which he is gifted by the Lord through regeneration, begins to feel some delight in good and truth itself, and to be affected by this, not for the sake of anything of his own, but for the sake of the good and truth; and when he is led by this delight, he disclaims merit, till at length he rejects it as an enormity. This delight grows with him step by step, and becomes blessed; and in the other life it becomes happiness, and is itself his heaven. Hence it is now evident how it is with each rational in the man who is being regenerated.

He who is being regenerated is led by means of truth to the intent that he may come to good, that is, may know it, and then will it, and finally do it. But when he is being led to good by means of truth, he first comes to the good in which the truths of faith have not yet been implanted; for truths cannot be implanted until he is in good. Before this they are indeed known, because they are in the memory, but at this time they are not in good, but are outside of good. Afterward when the man receives new life, which he first receives when he is in good, the truths of faith are implanted, and as it were enter upon a marriage with good in the internal man.

For during man’s regeneration he is first purified from the falsities which spring from the evil of the loves of self and of the world, which is effected by his receiving instruction concerning evil, hell, and damnation, and also concerning good, heaven, and eternal happiness; and by his thus suffering himself to be withheld from doing, willing, and thinking evils. When the soil has been thus prepared, then the truths of faith are sown, for before this they are not received. But the truths which are sown must be implanted in good, because they have no soil anywhere else, nor can they strike root anywhere else. They are implanted in good when the man wills the truth, loves it, and does it. This state of regeneration, or of liberation from damnation, is signified by this feast, which is called “the feast of the harvest of the first fruits of thy works;” for “harvest” signifies truths producing good.
