The meaning of parable of the sower

Luke 8:11-15

11 Now the meaning of the parable is this: The seed is the Word of God.

12 Those along the traveled road are the people who have heard; then the devil comes and carries away the message out of their hearts, that they may not believe ( acknowledge Me as their Savior and devote themselves to Me) and be saved [here and hereafter].

13 And those upon the rock [are the people] who, when they hear [the Word], receive and welcome it with joy; but these have no root. They believe for a while, and in time of trial and temptation fall away (withdraw and stand aloof).

14 And as for what fell among the thorns, these are [the people] who hear, but as they go on their way they are choked and suffocated with the anxieties and cares and riches and pleasures of life, and their fruit does not ripen (come to maturity and perfection).

15 But as for that [seed] in the good soil, these are [the people] who, hearing the Word, hold it fast in a just ( noble, virtuous) and worthy heart, and steadily bring forth fruit with patience.

I've been considering this parable for the past two weeks.  My biggest concern is

that my heart is good soil.  My son's Bible (New International Reader's Version)

says the good ground is an "honest and good heart". 

I'm also preoccupied with the thought that we can have ears that do not hear, eyes

that do not see/perceive, and a heart that does not understand.

Jesus said,

Luke 8:8

8 And some seed fell into good soil, and grew up and yielded a crop a hundred times [as great]. As He said these things, He called out, He who has ears to hear, let him be listening and let him consider and understand by hearing!

We have been given the chance to understand the secrets of God's kingdom.

I want to be ready to "hear" from God, so that I can produce fruit a hundred fold.

Luke 8:10

10 He said to them, To you it has been given to [come progressively to] know (to recognize and understand more strongly and clearly) the mysteries and secrets of the kingdom of God, but for others they are in parables, so that, [though] looking, they may not see; and hearing, they may not comprehend. [Isa 6:9,10; Jer 5:21; Ezek 12:2.]

We've been warned of what can happen.

Isa 6:10

10 Make the heart of this people fat; and make their ears heavy and shut their eyes, lest they see with their eyes and hear with their ears and understand with their hearts and turn again and be healed.

I'm not sure how it affects you, but when I consider where we can be without ears

to hear - it's frightening. Selah.  [pause, and calmly think of that]!

Well, I've got to go - kids and husband are running all around me.  It's Friday night

at the McDonald house.
