Why did Jesus choose to use Parables?  Why would someone who wanted the whole world to come to know God intentionally use stories, metaphors, and language that was often cryptic and hard to understand?  Shouldn’t He have put things in the plainest of language and boiled His Gospel of The Kingdom down into the 5 essential easily understandable points (eg. 1. God made you; 2. God Loves You; 3. You are a sinner; 4. Jesus died for your sins; 5. If you say you believe this you will get to go to heaven some day).  supported by ONE Main Point (eg. God Loves You)?  (Side Note: What about John 17:3? What is The Eternal Life?).  I mean, Matthew 13 with Parable after Parable after Parable after Parable seems like a barrage.  An overload.  A dump truck being dumped on humanity, on God’s children.  A waterfall.  Drinking from a Fire Hydrant.  Yes, exactly His Point.  The Methodology of Jesus, executed Powerfully and with Divine Precision, followed by a counterpunch by Satan, the ruler of the power of the air, our already defeated yet still being conquered enemy… (Revelation 12):

  1. Jesus Tells Parables
  2. Interested People draw close to Jesus to have personal conversation to learn more.
  3. This siphons out the people whose hearts and minds have been opened by The Holy Spirit (Acts 16:14; John 6:60-71; 8:31-38, 43, 47; 18:37)
  4. This prevents Jesus from wasting His Precious Time with those whose hearts are closed and arrogant, who could potentially (from a human perspective) cause a train-wreck of His Plan to produce 12 fully trained obedient disciple learners who would joyfully, intentionally, and powerfully reproduce themselves in others, following the multiplicative example and pattern that Jesus Himself used with them over 3 1/2 years.  (John 2:23-25)
  5. Whalla! The Gospel is off and running bearing multiplying fruit across the whole Roman Empire within 50-70 years.  (John 15:8)
  6. Take That Satan.  (1 John 3:8; John 16:11)
  7. Satan Responds by first killing Christians using the brutal Roman leaders (just like they he used them to crucify Jesus), and then when that had the opposite effect (“The blood of the martyrs is the seed of the church”), he used a sun god-worshipping guy named Emperor Constantine to make “Christianity” the official religion of the Roman Empire.  This brought much morality into the world and made it a more civilized existence for many human beings, but Christianity in my opinion also became weakened in some ways and less mobile/able to multiply quickly:  (the church is not a building.  church is not something you do or go to on Sundays.  the church is a people Called out by God, gathered together into One by God, sent by God to live as The Very Body of Christ with the purpose of healing the whole world by God’s Power working through us.  the church is the priesthood of all believers and the kingdom of God people who are obeying The High King (Jesus) and Great High Priest (Jesus) through listening to The Greatest Prophet (Jesus) who sent all the prophets by The Holy Spirit).

The Parable of the Sower  (Matthew 13)

13 That same day Jesus went out of the house and sat beside the sea. And great crowds gathered about him, so that he got into a boat and sat down. And the whole crowd stood on the beach. And he told them many things in parables, saying: “A sower went out to sow. And as he sowed, some seeds fell along the path, and the birds came and devoured them.Other seeds fell on rocky ground, where they did not have much soil, and immediately they sprang up, since they had no depth of soil,but when the sun rose they were scorched. And since they had no root, they withered away. Other seeds fell among thorns, and the thorns grew up and choked them. Other seeds fell on good soil and produced grain, some a hundredfold, some sixty, some thirty. He who has ears,[a] let him hear.”

The Purpose of the Parables

10 Then the disciples came and said to him, “Why do you speak to them in parables?”11 And he answered them, “To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. 12 For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away. 13 This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand.14 Indeed, in their case the prophecy of Isaiah is fulfilled that says:

“‘“You will indeed hear but never understand,
    and you will indeed see but never perceive.”
15 For this people’s heart has grown dull,
    and with their ears they can barely hear,
    and their eyes they have closed,
lest they should see with their eyes
    and hear with their ears
and understand with their heart
    and turn, and I would heal them.’

16 But blessed are your eyes, for they see, and your ears, for they hear. 17 For truly, I say to you, many prophets and righteous people longed to see what you see, and did not see it, and to hear what you hear, and did not hear it.

The Parable of the Sower Explained

18 “Hear then the parable of the sower:19 When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is what was sown along the path. 20 As for what was sown on rocky ground, this is the one who hears the word and immediately receives it with joy,21 yet he has no root in himself, but endures for a while, and when tribulation or persecution arises on account of the word, immediately he falls away.[b] 22 As for what was sown among thorns, this is the one who hears the word, but the cares of the world and the deceitfulness of riches choke the word, and it proves unfruitful. 23 As for what was sown on good soil, this is the one who hears the word and understands it. He indeed bears fruit and yields, in one case a hundredfold, in another sixty, and in another thirty.”

The Unbelief of the People (John 12)

When Jesus had said these things, he departed and hid himself from them.37 Though he had done so many signs before them, they still did not believe in him,38 so that the word spoken by the prophet Isaiah might be fulfilled:

“Lord, who has believed what he heard from us,
    and to whom has the arm of the Lord been revealed?”

39 Therefore they could not believe. For again Isaiah said,

40 “He has blinded their eyes
    and hardened their heart,
lest they see with their eyes,
    and understand with their heart, and turn,
    and I would heal them.”

41 Isaiah said these things because he saw his glory and spoke of him.42 Nevertheless, many even of the authorities believed in him, but for fear of the Pharisees they did not confess it, so that they would not be put out of the synagogue;43 for they loved the glory that comes from man more than the glory that comes from God.

Jesus Came to Save the World

44 And Jesus cried out and said, “Whoever believes in me, believes not in me but in him who sent me.45 And whoever sees me sees him who sent me. 46 I have come into the world as light, so that whoever believes in me may not remain in darkness. 47 If anyone hears my words and does not keep them, I do not judge him; for I did not come to judge the world but to save the world. 48 The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day. 49 For I have not spoken on my own authority, but the Father who sent me has himself given me a commandment—what to say and what to speak. 50 And I know that his commandment is eternal life. What I say, therefore, I say as the Father has told me.”
