Then the disciples came and said to him, "Why do you speak to them in parables?"
 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.
 For to him who has will more be given, and he will have abundance; but from him who has not, even what he has will be taken away.
 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.
 With them indeed is fulfilled the prophecy of Isaiah which says: `You shall indeed hear but never understand,
and you shall indeed see but never perceive.
 For this people's heart has grown dull,
and their ears are heavy of hearing,
and their eyes they have closed,
lest they should perceive with their eyes,
and hear with their ears,
and understand with their heart,
and turn for me to heal them.'
 And when he was alone, those who were about him with the twelve asked him concerning the parables.
 And he said to them, To you has been given the secret of the kingdom of God,
but for those outside everything is in parables;
 so that they may indeed see but not perceive, and may indeed hear but not understand; lest they should turn again, and be forgiven.
Matt.15You will observe that these words (Matt. 15:16) were spoken in a similar context, where he has quoted Isaiah 29:13,14. Yes, if one reads only Mark's version, predestination is suggested. But when one goes to Matthew and Isaiah, things come to Light.
 And he said, Are you also still without understanding?
 As they heard these things, he proceeded to tell a parable, because he was near to Jerusalem, and because they supposed that the kingdom of God was to appear immediately.
 He said therefore, A nobleman went into a far country to receive a kingdom and then return.
 Calling ten of his servants, he gave them ten pounds, and said to them, `Trade with these till I come.'
 But his citizens hated him and sent an embassy after him, saying, `We do not want this man to reign over us.'
 When he returned, having received the kingdom, he commanded these servants, to whom he had given the money, to be called to him, that he might know what they had gained by trading.
 The first came before him, saying, `Lord, your pound has made ten pounds more.'
 And he said to him, `Well done, good servant! Because you have been faithful in a very little, you shall have authority over ten cities.'
 And the second came, saying, `Lord, your pound has made five pounds.'
 And he said to him, `And you are to be over five cities.'
 Then another came, saying, `Lord, here is your pound, which I kept laid away in a napkin;
 for I was afraid of you, because you are a severe man; you take up what you did not lay down, and reap what you did not sow.'
 He said to him, `I will condemn you out of your own mouth, you wicked servant! You knew that I was a severe man, taking up what I did not lay down and reaping what I did not sow?
 Why then did you not put my money into the bank, and at my coming I should have collected it with interest?'
 And he said to those who stood by, `Take the pound from him, and give it to him who has the ten pounds.'
 (And they said to him, `Lord, he has ten pounds!')
 `I tell you, that to every one who has will more be given; but from him who has not, even what he has will be taken away.
 But as for these enemies of mine, who did not want me to reign over them, bring them here and slay them before me.'
It is all about Israel, about a collection of people who had, of their own free will, closed their minds to Truth. It was for reasons of their own doing that the kingdom was not given to them.
