Why are the two major parts of the bible called testaments?

Answer 1

This is because there was the time before Christ came to earth and which some of the rules at the Old Testament is followed by Jews and the rules in New Testament in which Christians follow this was the time when Jesus came to earth to die for us. that is why Christians and Jews are two completely different religions, also the New Testament contains happenings from day to day life and relates to us and the future to come.

the old testament is about people getting ready for christ to come and the new testament is about christ.

AND

A testament is an agreement or covenant. God made a covenant with the nation of Israel.

Lev 26:12 I will walk among you and be your God, and you shall be My people.

This is the old covenant / testament

Because the nation of Israel turned away from God and failed to keep their part of the covenant, God made it possible for all people to have a relationship with him through His Son Jesus.

Heb 9:15 And for this reason He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance.

This is the new covenant/ testament

Answer 2

The Old Testament talks about before Jesus's Birth, but the New Testament talks about after.

Answer:
While other reasons may appertain... one reason there are two testaments is because there is "duality" throughout The Bible... and creation. God is revealing His duality through this little-known and understood thread.

God made "two" sexes, which complete each other. The human body was created with "two" eyes, "two" ears, "two" lips, "two" arms, "two" legs, "two" feet, etc... all of which balance and completes the other.

Jesus said: "I and My Father are one..." (John 10:30)... a statement for which the Jews took up stones to kill Him. Nonetheless, He reveals the duality of God to the world - believe it, or not.

The Bible speaks of "two" Adams: "...The first Adam was made a living soul; the last Adam was made a quickening Spirit." (I Cor.15:45)

It speaks of the "two" deaths. The first death is the one all men die (Heb.9:27), but it's the "second" death from which Jesus saves us: "...He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death." (Rev.2:11)

There are "two" Resurrections and "two" Judgments. Those whom God is calling now (He's not trying to save the whole world, yet)... and who are Christ's, are being Judged now: "...for the time is come that Judgment must begin at the House of God..." (I Peter 4:17) -

Christ's saints shall be immediately rewarded according to their works upon His return. But the rest of mankind will be judged a thousand years later, after Christ and His saints rule over the nations, as prophesied.

"...Blessed and Holy is he that hath part in the firstresurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years." (Rev.20:6)

Other examples exist of duality in the Bible... i.e., the "Two Witnesses"... and the "two testaments."

The first testament was bound up in mystery and uncertainty. It was "sealed" from the understanding of men until the last days, when it would be revealed to those whom God is calling to rule His Kingdom with Him.

"...O, Daniel, shut up the words, and seal the book, even to the time of the end... the words are closed up and sealed till the time of the end... none of the wicked shall understand; but the wise shall understand..." (Dan.12:4; 9-10).

The second testament illuminates the first, once clouded in mystery. Jesus Christ is the Spiritual light of understanding that shines in the hearts and minds of those who are His. JESUS CHRIST IS THE REVELATOR - Rev.1:1.

And His disciples have bound up and completed the testimony of God in these last days that only "the wise" will understand (hint: "...the fear of the Lord is the BEGINNING of wisdom..." - Prov.9:10).

"Bind up the testimony, seal the law among My disciples." (Isa.8:16)

The two testimonies complete the Word of God for man's wisdom, knowledge and understanding. The second reveals the Spiritual Truth hidden in the first.

"...Then opened He their understanding, that they might understand the scriptures." (Luke 24:45).

Answer 3

There are two major parts to the bible the old testament and new testament.

Answer:

If you had lived 2000 years ago and had asked the Apostle Peter, Paul or John about the 'Old Testament' or the 'New Testament,' they would have had no idea what you were talking about. These terms were coined by men long after the books of the Bible were written. The 1st use of the term 'New Testament' for the Greek Scriptures is not found until a century or more after the death of the Apostles.

Some people today assume that the Old Testament with a God of wrath, as old or obsolete needing to be replaced by the New Testament with a God of love. This is totally a wrong conclusion as Christ taught we are to live by every word of God and quoted many times from the OT Scriptures (only Scripture around at His time).

Some Bible translations do have a few places where they use the designations 'Old Testament and New Testament' However, the word translated testament is also the word for 'covenant' both Old and New and is a better translation.

Considering that the Bible has 773,000 words and nearly 80% of them are written in the Hebrew Scriptures, it would be illogical to disregard this history of God's revelation, His revealed way of life, future prophecy and the promises He made to all mankind.
