...And when much people were gathered together,
and were come to Him out of every city,
[Jesus] spake by a parable:
A sower went out to sow his seed; and as he sowed,
some fell by the way-side; and it was trodden down,
and the fowls of the air devoured it.
And some fell upon a rock; and as soon as it sprang up,
it withered away, because it lacked moisture.
And some fell among the thorns;
and the thorns sprang up with it, and choked it.
And others fell on good ground,
and sprang up, and bore fruit a hundredfold...
And when he had said these things, He cried,
He that hath ears to hear, let him hear.
And His disciples asked Him, saying,
What might this parable be?
And He said...
Now the parable is this:
The Seed is the Word of God.
Those by the wayside are they that hear; then cometh the devil,
and taketh away the Word out of their hearts,
lest they should believe and be saved.
They on the rock are they, which, when they hear,
recieve the Word with joy;
and these have no root, which for awhile believe,
and in time of temptation fall away.
And that which fell among the thorns are they, which,
when they have heard, go forth,
and are choked with cares and riches and pleasures of this life,
and bring forth no fruit to perfection.
But that on the good ground are they,
which in an honest and good heart, having heard the Word,
keep it, and bring forth fruit with patience.

From Luke, Chapter 8
