The NT cannot be properly understood without Torah.
Read the five books.
I don't think the rest necessarily have to be in the order written, but the first five books were given directly to Moses by the Word of YHWH.
To ignore them is to ignore Jesus.
To understand Jesus' life as a human you must know something of His life before He was a human. His presence, though often carefully disguised in translation, is throughout the OT.
God didn't just give judgement to Him when He was "begotten."
He had judgement, I believe, from the beginning.
It was through Jesus that all things were created- nothing that has ever come into being came into being without Him.
And John 1:17- Because the Law was given through Moses grace and truth came into being through Jesus Christ. (I recently started picking through John in the Greek- that is how the Greek reads).
A lot of Christians believe that they are not under the Law, not a point I care to argue here, but also believe that the Law is impossible to keep (which would make no sense since many in the Bible are upheld as righteous and walking blameless in God's Law). Only by reading and contemplating the Law, which actually refers to the ENTIRE TORAH, (which is called "The Law" or "The Book of the Law"), can the NT writings about the Law be in any way understood and appreciated.
If you don't read and know Genesis, then you won't understand that Abraham had a personal relationship with Jesus (read starting at Genesis 15 with John 1:1 firmly in your mind).
You can also read about the New Covenant and see for yourself exactly what God expects from you and what your reward will be. A passage I marked recently relating to this is Jeremiah 31:31. It does not include the gentiles in the ff passages, but it is instructive none-the-less. Ask yourself if Jeremiah 31:34 applies to our times, and carefully consider what God promises.
Jeremiah 32:40 and the surrounding verses are also very instructive regarding God's promise.
Ezekiel 18:21-23 "But if the wicked man turn from his all his sins which he has committed and observes all of My statutes and practices justice and righteousness, he shall surely live; he shall not perish. All his transgressions which he has committed will not be remembered against him; because of his righteousness which he has practiced, he will live. Do I have any pleasure in the death of the wicked," declares the Lord God, "rather than that he should turn from his ways and live?"
It is so essential that the bible be in context.
The New Testament relies on the Old Testament for its foundation.
To not have read the Old Testament at least once before contemplating verse by verse any part of the New is to build your spiritual house on sand.
Bless up!
