Matthew 13:23

Beareth fruit; he receives the truth into the heart, and acts under its abiding influence. This represents the pious, the friends of God and men. They are all useful, but some more so than others. These truths, as to the various effects of the gospel, it was important that his disciples, who were to be preachers of it, should understand. They desired to understand them, and to them the understanding of them was given; while to his opposers, who did not wish to understand them, it was not given.
