Is the old Testament necessary today?

We all hear it said. We have even said. “That’s old Testament stuff.” We say it as though the old Testament is no longer relevant. We say it as though it is something we have progressed past.
Old Testament is a term that came from the Biblical referral to the old covenant which required animal sacrifice, and the new covenant which is Jesus’s sacrifice. Calling the books that went from Genesis to Malachi old Testament and the books that went from Matt. To Revelation New Testament, began in 130 AD by a Bishop who was separating the books this way for clarity in a letter he was writing. Shows as easily things catch on.

We see old as a bad word. A subversive content that we need to avoid. I actually heard a girl the other day, (she was probably 14yrs old,) say, after looking at a designation plaque that honored an old lady who had passed away after being a patriarch of the area we were in, “why would they give that to her?” (Tone is everything in the illustration so try and hear the degrading whine in the voice) her mom explained the memorial. She then said, “so what? They just give these to old people. I don’t want her to have it.”
Welcome to 2023. Anyway. This is how old is seen. Not relevant or valuable. So the term ‘old’ being used for the pre-Jesus covenant marks the book unfairly.
So many who are confronted by the Old Testament want to do away with it. They do the, “Jesus made it irrelevant. Paul said it’s the law of death.” Thing. Yet Jesus Himself said:
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
Matt. 5:17 NIV
And Paul was addressing learned Jewish men as well as gentiles when he was speaking. These statements were for these men who were using the law to empower themselves and contorting it to fit their own agendas. The law they commanded was the law of death Paul meant. I would even go so far as to say that what is being preached in certain Churches today, that has been contrived from scripture and then mutilated to fit certain non offensive agendas, has become a law of death too. It’s no longer the Truth that guides you to Heaven, it’s just nice platitudes that fills seats and not souls. Working the Bible to your own life and choices is what the Pharisees and Sadducees did that caused many problems and eventually led Paul to make his bold statement. The Pharisees and Sadducees started out as great people. Dedicated to God and on the right path, until they slid off that path and started using their positions to further themselves instead of God. Sounds like many preachers today, doesn’t it?
However we are now off track. Jesus quoted the Old Testament when battling the devil. Paul himself often quoted the Old Testament. Matt. Mark. Luke and John quoted the Old Testament. If the guys who established the New Testament found the Old relevant enough to refer to it and quote it, then what makes us think that we have moved to a place of spiritual enlightenment that we can throw it away? It’s because a lot of the hard truths are in the Old Testament, truths we want to hide from so we ignore them. Yet most of those truths, rules and warnings were reestablished by either Jesus Himself or one of the New Testament writers.  And Don’t forget. If you throw out the Old Testament you also lose all the Psalms. How many of us rely on those Psalms to get us through a tough week?
Jesus made it clear with His own words that the Old Testament is still relevant and valuable and necessary, who are we to argue with Him?
