We can say Jesus perfected the existing standards of holiness, but the new yardstick was brought only after the cross.
Let's see Jesus' response in Matthew 12:11, when He was accused of breaking the Sabbath:
11 He said to them, “If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? 12 How much more valuable is a person than a sheep! Therefore it is lawful to do good on the Sabbath.”
If the Law was no longer in force at that time Jesus would have responded with something like: "I have already released you all from the bondage of the Law". There would be no need for any other justification at all. When Jesus says "it is lawful to do good on the Sabbath" He is perfecting the law of Moses.
“The Law and the Prophets were until John".
Luke doesn't say here that the Law was in force only until John and evidently it was in force throughout Jesus' earthly ministry because He said "obey the scribes and the Pharisees".
My view is from heaven to man.
Your view is from man then lateral.
You take what you think "is" then apply it under a need to stand in the concept that the gospels are part of the ot.
That is what drives your view.
You are needing the ministry of Jesus to change nothing.
You need everything he stood for to be " under the law"
Because of the priesthood changing,the new covenant was set in motion.
That is being totally,completely left out.
