Well to be fair the problem with the Jews was that their tradition had put scripture in second place. Their learned interpretations and opinions of scripture were in error and they had lost their way because of tradition.
But once Christ began to teach them that their tradition was screwing things up, many began to REALLY read the scriptures without the prism of incorrect tradition screwing things up.
The wool fell off from their eyes.
Oh for sure.. the lessons to be learned is how the Jews, save small groups of people and small tribes, did not obey the voice of God, and when Jesus came in flesh, he told us to look at the Spirit of the Law, not the letter of the law. That is why he was making his stand as a Rabbi from the House of Hillel and walking out the gospel, his ministry and then dying a powerful death- making the story complete. BUT it started at the beginning and then with the Jews- and ended with Jesus. It is a full and complete story. We can’t start in the middle. We have to read the beginning to see where they made their error and WHO made the error. There were always small groups of people who obey the commandment to follow the voice of God. When the word became flesh- and gave sound and blood to the word- we have a good map of what to do.
There is a reason why we see how hard it was for them to follow the voice, before the word became flesh. It is for our benefit to contemplate that very thing. :)
God loves us- so he imparts these things to us.
But don’t disregard all of their traditions and festivals and teachings either.. I should have said, because you will miss a lot of understanding.
There is a reason for everything Jesus said and did in the NT, and the answers are in the OT.
Jesus did come to uphold those laws. So don’t throw them away. Think about them. You will be blown away at what you come to realize. I promise. :)
