If it were that simple we would all be blind.
Mark 9:47,
And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
Just because there is a page in all Bible's right in front of Matthew that say in big bold letters, "The New Testament" doesn't mean that is where the New Testament actually begins.
First of all, everything written before Jesus' birth was written so that Israel would recognize their redeemer. Jesus came to set up an everlasting kingdom. That is plain to see from reading Genesis to Malachi. Essentially the Bible is a book about Jesus, who in turn reveals God to the world.
Luke 24:27,
And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.
John 5:39,
Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
Of course, despite God's best efforts, Israel, at least the religious leaders, not only didn't recognize Jesus as their redeemer, they actually had him killed. Without the king the kingdom was put on hold. The book of Revelation is all about Jesus' second coming when all promises concerning the promised kingdom will come to pass. It is also spoke of in Jeremiah.
Jer 31:31,
Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
While taught for thousands of years that we are now in the "new testament" Jeremiah clearly indicates that not to be the case. The New Testament is between God and His chosen people, i.e. Israel. Neither the Old Testament nor the New Testament have anything to do with the Gentiles.
So where do the Gentiles come in the picture? They are taken care of in the books of Acts through Jude. Basically, during this period God deals with both Jew and Gentile in a completely different way than He dealt with Israel before Jesus' first coming and how He will deal them at his second coming.
Ephesians offers a good summary of what God is doing in the period between Acts and Jude:
Eph 2:11-22,
11 Wherefore remember, that ye [being] in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition [between us];
15 Having abolished in his flesh the enmity, [even] the law of commandments [contained] in ordinances; for to make in himself of twain one new man, [so] making peace;
16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
17 And came and preached peace to you which were afar off, and to them that were nigh.
18 For through him we both have access by one Spirit unto the Father.
19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner [stone];
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit.
Do a word study on "mystery" in Paul's epistles. The Greek word "musterion" is better translated as secret. Once revealed, a secret can be understood. It'll take time and much thought, but if you do, you will see that Paul reveals to us in this day and time what the resurrection of Jesus really meant for all mankind, not just Israel. After all, wouldn't you think something grand must have happened by the resurrection of a man from the dead? Of course! It was a game changer to the nth degree. The things we have available to us in this period of time were not available before Christ rose from the dead, and they won't be available once he returns to fulfill all the promises God made to Israel concerning and everlasting kingdom. That is the very subject of the secret God revealed to Paul. Prior to that revelation to Paul, nobody had a clue of the secret.
1Cor 2:7,
But we (Paul) speak the wisdom of God in a mystery (secret), [even] the hidden [wisdom], which God ordained before the world unto our (born again believers) glory:
Eph 3:4-9,
4 Whereby, when ye read, ye may understand my knowledge in the mystery (secret) of Christ)
5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
7 Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.
8 Unto me, who am less than the least of all saints, is this grace given, that I (Paul) should preach among the Gentiles the unsearchable riches of Christ;
9 And to make all [men] see what [is] the fellowship of the mystery (secret), which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
I wouldn't blow anything I've said without spending much time in considering what the scriptures I've quoted have to say. If you spend the time to understand the implications of these things it'll change your life and your relationship with God and with His son, our Lord and Saviour Jesus Christ.
Acts 17:11,
These (the Bereans) were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things (that Paul told them) were so.
Paul encouraged them to not just take his word for it. He encouraged them to study the scriptures to see if the things he said were true or not. The very next verse says that because they did what Paul suggested, many of them believed.
Acts 17:11,
These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
When it comes to the words of life, opinions must take a back seat, the seat as far back as possible. When it comes to truth, the only rule of faith and practice ought to be the scriptures and nothing but the scriptures!
God bless...
