Matthew 13:10-17
10 Then the disciples came to Him and asked, “Why do You speak to the crowds in parables?”
11 Jesus replied to them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted. 12 For whoever has [spiritual wisdom because he is receptive to God’s word], to him more will be given, and he will be richly and abundantly supplied; but whoever does not have [spiritual wisdom because he has devalued God’s word], even what he has will be taken away from him. 13 This is the reason I speak to the crowds in parables: because while [having the power of] seeing they do not see, and while [having the power of] hearing they do not hear, nor do they understand and grasp [spiritual things]. 14 In them the prophecy of Isaiah is being fulfilled, which says,
‘You will hear and keep on hearing, but never understand;
And you will look and keep on looking, but never comprehend;
15
For this nation’s heart has grown hard,
And with their ears they hardly hear,
And they have [tightly] closed their eyes,
Otherwise they would see with their eyes,
And hear with their ears,
And understand with their heart, and turn [to Me]
And I would heal them [spiritually].’
16 But blessed [spiritually aware, and favored by God] are your eyes, because they see; and your ears, because they hear. 17 I assure you and most solemnly say to you, many prophets and righteous men [who were honorable and in right standing with God] longed to see what you see, and did not see it, and to hear what you hear, and did not hear it.
Mark 4:10-12
10 As soon as He was alone, those who were around Him, together with the twelve [disciples], began asking Him about [the interpretation of] the parables. 11 He said to them, “The mystery of the kingdom of God has been given to you [who have teachable hearts], but those who are outside [the unbelievers, the spiritually blind] get everything in parables, 12 so that they will continually look but not see, and they will continually hear but not understand, otherwise they might turn [from their rejection of the truth] and be forgiven.”
Luke 8:9-10
9 Now His disciples began asking Him what this parable meant. 10 And He said, “To you [who have been chosen] it has been granted to know and recognize the mysteries of the kingdom of God, but to the rest it is in parables, so that though seeing they may not see, and hearing they may not understand.
