What, you don't think we have a copy of the scriptures??? That wasn't it...Jesus knew they didn't believe anything...Jesus knew that they didn't believe he was the Messiah...Jesus knew that from the beginning...
Which He said about 5 or 6 times, so they couldn't miss it.
Luk 8:10 And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.
Luk 10:21 In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight.
Psa 25:14 The secret of the LORD is with them that fear him; and he will shew them his covenant.
Mat 11:25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
Mat 13:10 And the disciples came, and said unto him, Why speakest thou unto them in parables?
Mat 13:11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
Mat 13:12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
Mat 13:13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
Mat 13:14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
Mat 13:15 For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
Mat 13:16 But blessed are your eyes, for they see: and your ears, for they hear.
And THAT is why Jesus didn't call them back to tell them the truth...
Mat 16:17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
1Co 2:7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
1Co 2:8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
1Co 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
1Co 2:10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
WHY do we ‘need’ any NT at ALL??
Did not Jesus say, “...they have Moses and the prophets...”?
Didn’t Paul ‘reason with them from the (OT) Scriptures’?
Were not THOUSANDS converted and their names written in the Lamb’s Book of Life LONG before the NT was assembled?
