"He also that received seed among the thorns is he that heareth the word; and the care of this world, and the deceitfulness of riches, choke the word, and he becometh unfruitful." Matthew 13:22
The gospel seed often falls among thorns and noxious weeds; and if there is not a moral transformation in the human heart, if old habits and practices and the former life of sin are not left behind, if the attributes of Satan are not expelled from the soul, the wheat crop will be choked. The thorns will come to be the crop, and will kill out the wheat.
Grace can thrive only in the heart that is being constantly prepared for the precious seeds of truth. The thorns of sin will grow in any soil; they need no cultivation; but grace must be carefully cultivated. The briers and thorns are always ready to spring up, and the work of purification must advance continually. If the heart is not kept under the control of God, if the Holy Spirit does not work unceasingly to refine and ennoble the character, the old habits will reveal themselves in the life. Men may profess to believe the gospel; but unless they are sanctified by the gospel their profession is of no avail. If they do not gain the victory over sin, then sin is gaining the victory over them. The thorns that have been cut off but not uprooted grow apace, until the soul is overspread with them.
Christ specified the things that are dangerous to the soul. As recorded by Mark He mentions the cares of this world, the deceitfulness of riches, and the lusts of other things. Luke specifies the cares, riches, and pleasures of this life. These are what choke the word, the growing spiritual seed. The soul ceases to draw nourishment from Christ, and spirituality dies out of the heart. COL 50, 51
Riches do not endure forever. Proverbs 27:24 (New International Version)
