I want to clear up a misconception some people have because the Bible is divided into two parts (The Old Testament and The New Testament).
The Bible has to be one of the most attacked books in history, it’s validity has been questioned numerous times, it’s writings have been twisted more than anything written. Among some of those who are willing to admit it is from God there are people who have decided to only believe some and throw the rest out (**though there are scriptures that teach us what is applicable for today from what is not, we still need to be aware of all that is written**). There are Orthodox Jews and wanna be Jews (BHI) who hold the Torah (Books written by Moses) to be the most sacred and the only thing we are to follow, they disregard the writings of Paul and the other Apostles. Then there are also those from certain sects who think we are to keep the ten commandments and cherry pick out of the other hundreds of laws a few they feel we are to follow. They focus primarily on the Sabbath, not eating pork or any shellfish, not wearing make-up (which isn’t a law), and end time prophecies in the Book of Revelation and Daniel. Though when it comes to this sect’s teachings I wonder to myself, what is the point in being able to understand or believing you fully understand what’s going to happen at the end of the world yet have little to absolutely no understanding of the difference between the Old and New Covenant and what all we have gained in Christ, what all we have been liberated from, what all we have been given?
The first 39 books of the Bible is not the Old Covenant, the first 39 Books of the Bible are the writings of Moses and the Prophets BUT it is (within) these first 39 Books we have the Old Covenant, but all 39 books itself are NOT in total the actual Old Covenant. The actual Old Covenant are (ALL) the (Laws given to Moses on Mount Sinai). (Hebrews 9:8-22, Exodus 24:7-8, Galatians 4:21-31, Hebrews 8:7-13) shows this but to get a better understanding of what the Old Covenant is, it is beneficial to study Romans, Galatians, and Hebrews thoroughly especially to see how Christ fulfilled the law. The Books in the Old Testament that have the actual Old Covenant Laws and Principles are Exodus. Leviticus, Numbers, Deuteronomy. Most of the Books in the Old Testament however are during the time when people were living under those laws because Christ had not yet been born of a virgin, crucified, died, and resurrected ushering in and establishing the New Covenant and making obsolete the Old Covenant (Hebrews 8:13). I think because the two parts of the Bible are called testaments that has some people a bit confused, but this wasn’t intended to confuse the readers but I think these were to really present a timeline so people are able to know when the events in each half of the Bible happened, kind of how we have BC and AD.
Yes, within the first 39 books we have the laws of Moses BUT there are also writings from Prophets warning the Jews on various occasions to repent or they would be taken into bondage (which happened) or their land would experience plagues from God, (which also happened) all because of disobedience and disbelief. The Old Testament also has prophesy about the appearance of Christ by virgin birth Isaiah 7:14-16, Isaiah 9:6-7). Also these Prophets prophecy what will be fulfilled during times after the old covenant has already been established, that would be our times. Important to note that The New Covenant was mentioned in both halves of the Bible, (Jeremiah 31:31-35, Hebrews 10:16, Hebrews 8:10)
The last 27 Books of the Bible are not the New Covenant, however (within) these books we are taught the meaning of the New Covenant and how to live under this covenant. Among the pages of these 27 books we have the virgin birth, crucifixion, death, burial and resurrection of Jesus Christ, He who came to fulfill the law and establish the New Covenant. We also have the 4 eyewitness accounts of all of this (though there were of course far more than 4 people who witnessed these events), we know that by the word of 2 or 3 witnesses every word is established (2 Corinthians 13:1), so we know why we have these 4 accounts of the same story, it is so that every word may be established, plus we have the writings of Paul, Peter, Jude and of John which also bears witness of Jesus Christ as being the Son of God and our Lord whose precious blood is what redeems us from our sins and who brings mercy and forgiveness to all who repent 1 John 1:9.
These 27 books are a collection of writings that show us the revelation of the Christ prophesied of in the first 39 books of the Bible. These 27 Books also teach and reveal to us what all Christ had to suffer and why He suffered. Within these 27 Books we see that it was God Himself in Christ reconciling the world to Himself. (2 Corinthians 5:19). These 27 Books also shows us what He requires of us today in our conduct in order to truly be living by faith (Romans 1:17, Galatians 3:11, Hebrews 10:38), righteous, godly, holy(1 Peter 1:16, 2 Peter 3:11), and perfect(Matthew 5:48) in His eyes. Also we are taught the greatest of all commandment which is to love God with all of our heart, mind, soul, and strength(Luke 10:27, Matthew 22:37), and to love others the way He loves us (John 13:34). Within these 27 Books we have revealed to us grace and truth brought through Jesus Christ (John 1:17).
Within these 27 Books we see that righteousness is not obtained through the works of the law but is only achieved through faith in Jesus Christ alone, He who was the only one able to meet all the righteous requirements of the Law and whose imputed righteousness we have if we abide in Him, (Romans 3:20, Romans 3:28, Galatians 2:16, Galatians 2:21, Hebrews 10:11-14). And within these books we have the testimony of the Father that Jesus Christ is His Son in whom He is well pleased (Matthew 3:17, Matthew 17:5), we also have the Father’s testimony that Eternal life is ONLY through His Son Jesus Christ, (1 John 5:9-13). God the Father wants us to listen to His Son, He who is far greater than Moses and the Prophets has come and God has spoken from heaven in the presence of Moses (Law) and Elijah(Prophets), (Peter, James and John being at a distance but serving as witnesses), telling us to listen to His son. “Then a cloud appeared and enveloped them, and a voice came from the cloud: “This is My beloved Son. Listen to Him!” Mark 9:1-8. Sadly, today many listen and obey the traditions and commandments of men, but we know that those who are indeed of Christ only listen to Christ and follows Him alone, (John 10:27). In the last Book in the New Testament we see the return of Jesus Christ.
Although as believers in Christ saved by grace through faith so we are not are not under the laws of Moses, it is still great to have an understanding of the laws that Christ came to fulfill, so we don’t throw out even those books because even they point to that which is greater than Moses and his laws, Jesus Christ. Also, in the New Testament it is said in 1 Corinthians 10:11 that all of what was written is for our admonition, to warn us basically so we do not follow in the steps of those who rebelled against God. So that is an additional reason out of many why the first 39 Books of the Bible is not only relevant but necessary for us to read and understand, it’s not to be disregarded or just glanced at barely for the sake of boasting that you have read the entire Bible. Boasting about reading the entire Bible is nothing, I have seen atheist do that (though I don’t believe them), what matters is having a perfect understanding of the word of God and (doing) what God wants us to do today and that is live by faith, believe in Jesus Christ His only begotten Son, love God with all our heart, mind, soul and strength, and love others the way He loves us.
In conclusion, in order to understand the will of God, in order to understand what all we have gained in Christ, we must read all 66 Books of the Bible, not merely glossing over it, but carefully reading it and understanding it all in it’s (proper context), this is vital in order to not be led astray by various winds of doctrine that are coming from all over the place to deceive those who have not come to know and believe the truth.
“I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, which is not another; but there are some who trouble you and want to pervert the gospel of Christ. But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed.” Galatians 1:6-9
