Len, Tim, Ro and others have made some good comments here. I agree that 'All scripture is God-breathed and useful...
... It is of great value to have a good understanding of all scripture.
That being said, Your questions are very important. I believe ALMOST ALL doctrinal differences and denominational splits are caused by one major misunderstanding:
There have been several major 'plot twists' in the Bible, as God has been illustrating spiritual truth thru human history. The one that confuses people most is that until the 'dispensation of grace' given to the world thru Paul,
the world was under the law, or the 'circumcision dispensation', which would include the scriptures of the
Old Testament, the Gospels, Hebrews, and the epistles of Peter, James, John and Jude.
While there are good teachings throughout the Bible, where the confusion comes in, is trying to mix these teachings together that are directed at 2 different groups.
Trying to mix 'Law & Grace' is a recipe for disaster! (Many a believer has 'shipwrecked their faith' this way.)
Due to a lack of understanding many today try to put Believers under the law, or unbelievers under grace,
adding to the confusion.
It is in the epistles of Paul and the 'transitional' book of Acts that God repealed the law of circumcision for
the Body of Christ. So they should be considered not more important, but more relevant for day-to-day living for members of the Body of Christ, in my opinion.
I'm sorry for all these questions. I just don't know these things.
There's the old testament and the new testament. Jews and Greeks. Circumcision and uncircumcision. Law and grace. Old covenants and new covenants. It's all so confusing.
It seems that different parts of the bible apply to different people at different times.
What part of the bible am I suppose to be following today? I mean, what part of the bible is still relevant to living life in our modern society?
Dee, I don't believe I've seen you post here, since I have been, so I don't know if you will see this, but I believe I have answered your question. All scripture is important to understand, but you are right that it applies to different groups at different times. God wants us to see the 'big picture, & the entire plot,' as it teaches us a great deal.
As far as your last question about relevancy today: Read The Pauline Epistles.
But don't forget what the others said about other parts of scripture.
I love to read: Genesis, Exodus, Leviticus, Isaiah, Psalms, Proverbs, John, Acts, Romans, and all the Pauline epistles.
I always love to read the words of Jesus as well, you just have to keep in mind, in general, He was speaking to Israel,
(those under the law) that should help you avoid confusion, even though the general principles are relevant and so much can be gleaned from the parables.
