Luke 8:10-13

And he said, Unto you it is given to know the mysteries of the kingdom of God: but to the rest in parables; that seeing they may not see, and hearing they may not understand. Now the parable is this: The seed is the word of God. And those by the way side are they that have heard; then cometh the devil, and taketh away the word from their heart, that they may not believe and be saved. And those on the rock are they who, when they have heard, receive the word with joy; and these have no root, who for a while believe, and in time of temptation fall away.
