If the Old Testament is sufficient then why New Testament? Yes, it was sufficient for those to whom it
is given by God. But for us, it is not enough. God has revealed himself fully and finally in His Son,
Jesus Christ. As there is a reason or purpose for every work of God and man so, there are some reasons
to read NT. They are as follows:
1. The Bible as God’s words and His only unified book:
The bible is God‘s words and His only book in this world though there are many writers and 66 books.
It is because God has spoken to His People and the world at many times in many ways through many
people, who have known the prophets, people called by God to receive God‘s words and to
communicate them to the people. And finally, He has spoken through His only Son, Lord Jesus Christ.
The message of the bible is about God‘s particular task, God‘s revelation, God‘s charge or
commandment to His people. Thus, the bible communicates us Jehovah as the only living and true God,
whose glory fills the heavens, but who is ever close to His people. It tells us about sin, which is
considered as a breach of the relationship with God. Finally, the result of this sin is the judgment from
God and also a restoration of God‘s people to his favor and the blessing of the eternal and abundant
life. In other words, God is the Sovereign God above all. He is ruling over all powers of this world to
fulfill His plan throughout all human history. Thus, Bible must be viewed and approached as both
organically unified and historically progressive. To understand them, you must read the Bible.
2 Its historical-Progressive redemptive theme:
The Bible also makes it clear that God has a unified plan for all of history. His ultimate purpose, ―a
plan for the fullness of time,‖ is ―to unite all things in him [Christ], things in heaven and things on
earth‖ (Eph. 1:10), ―to the praise of his glory‖ (Eph. 1:12). ―When the fullness of time had come,‖
when the moment was appropriate in God‘s plan, ―God sent forth his Son, born of woman, born under
the law, to redeem those who were under the law‖ (Gal. 4:4–5). Thus, the bible is the revealed record of
God‘s redeeming purpose and accomplishment. All human history is set within this purpose. The
biblical addresses are relevant to the revelation of redemption and its instruction about the person and
the will of God. Therefore, revelation is the interpretation of redemption; it must, therefore, unfold
itself in installments as redemption does. It is because God is the central protagonist in the biblical
record, yet He reveals Himself primarily through the lives and lips of men. Little of the Old Testament
consists of stories about God. God is observed in historical events and circumstances. Hence, the
theocentricity of the Old Testament is seen in its anthropocentricity. But now redemption could not be
otherwise than historically successive, because it addresses itself to the generations of mankind coming
into existence in the course of history (Vos).4
Finally, we can see the final realization and fulfillment of
God‘s redemptive purpose, which has begun in OT, in the incarnation, ministry, death, resurrection,
ascension, and glorification of Immanuel, Our Lord Jesus Christ.
3. NT as the Fulfillment of Old and the beginning of New:
After the fall of Adam and Eve, the representative of all creations before God, his descendants were not
able to keep the Law of God, instead, they invented all sorts of sins. Thus, God killed all human beings
except Noah and his family. As the number of people increased, they have sinned against God. They
started to build the tower, which was not according to His will. And God confused their language. Still,
they did not learn any lesson from it. God left them in their sinfulness. Again God chose Abraham
instead of killing everyone to make a nation called Israel to reflect His Holiness to the world. Also, the
people of Israel failed to represent God before the world so God sent them to be a save of Egyptians.
After 400 years, God delivered them from the Egyptians slavery and gave them the written Laws. They
promised to keep them. But they could not obey God. This story of ―People‘s Promise to keep the Law
and their Disobedience to the Law and the punishment of God‖ repeated again and again through the
promise to send the Messiah was clear in the Law, Prophets, and Psalms. But they did not wait for
God‘s time. It happened because they could not have firm faith in God. In the fullness of time, God did
not send His Son to pay the ransom of sin but He also crucified the sins for all the times. In this way,
God redeemed His people from the bondage of sins by fulfilling the Law. Also, He began NCC to
fulfill His promises in His ways by Himself. Now OT for us is for example (Rom. 15:4; 1 Cor. 10:11).
Thus, Jesus Christ came to this world to fulfill to establish NC.
4. To behold Jesus Christ and His Glory with the unveiled face:
―… For this day, when they read the OLD COVENANT, that same VEIL remains unlifted, because
only through Christ is taken away. Yes, to this day when Moses is read a veil lies over their hearts. But
when one turns to the LORD, the veil is removed. Now the LORD is the Spirit, and where the Spirit of
the LORD is, there is freedom. And we all, with UNVEILED FACE, BEHOLDING the glory of the
LORD, are being transformed into the same image from one degree of glory to another. For this comes
from the LORD who is the Spirit. (2 Cor. 2: 14-18).‖5
This passage of NT tells about the superiority of
NT over OT. To show you the full scope of NT, let me bring the teachings of the Four Apostles, Paul,
Peter, John, and James, who are very close to the LORD.
5. Testimony of the Holy Spirit and Apostles about NT:
Paul, an apostle of faith and for gentiles, explains NT as the words of salvation. He, in his speech in
the synagogue at Antioch, provides us a clear picture of the exaltation of the New Testament. After the
customary reading of the Law, He rehearsed a bit of Jewish history. At the very mention of Jesus in
Acts 13:26, he said, brothers, sons of the family of Abraham, and those among you, who fear God, to
us has been sent the Message (the word) of this salvation (emphasis added). The word of salvation
comes to the world only through the New Testament of Jesus Christ. It is the word of truth, the gospel
of your salvation (Eph. 1:13). Similarly, Peter, an apostle of Hope and for Jews, see NT as the means
to eternal life. Hearing the Master, he quickly said that Jesus has the words of eternal life (John 6:68).
Again, after the Jews rejected Paul‘s words, he spoke to Gentiles. And when the Gentiles heard this,
they began rejoicing and glorifying the word of the Lord, and as many as were appointed to eternal life
believed (Acts 13:48 ESV). The way to have eternal life is revealed in this word of salvation (2
John, an apostle of Love, perceives NT as words of true joy and happiness. He wrote, ―And we are
writing these things so that our joy may be complete or full (1 John 1:4; See also 1 John 5:11). Many
documents have been written on the pursuit of happiness, but it is this wonderful New Testament that
gives reality to happiness and peace with God. Jesus said, I have said these things to you, that in me
you may have peace. In the world, you will have tribulation. But take heart or be of good cheer; I have
overcome the world (John 16:33). He left us his word of peace and happiness in the New Testament for
us to study and obey.
James, an apostle of work, says ―faith without work is dead (Jam.1: 26)‖. It means ―faith works.‖ Faith
must be proven by the works. Mere faith or dead faith cannot produce justification. Also, works
without Faith in God (dead works) cannot justify anyone before God. Faith and works according to

faith must go together. It is like two sides of a coin. In the absence of one side, a coin is no longer a
coin. It means it is useless or equal to nothing.
Again Peter says NT as all man needs to be right with God (2 Pet. 1:3). All that pertains to life and
godliness has been revealed to us. Peter said he would not be negligent to put his readers in
remembrance of things they knew and in which they were well established. It was the present truth of
which he continued reminding them (verse 12). The Old Testament is truth, but it is past truth. It
furnishes the foundation for New Testament truth. Thus, NT reveals the faith (Gal. 3:22-25). Becoming
obedient to the gospel, thousands of Jews and Gentiles obeyed the faith (Acts 6:7). Saving faith comes
by hearing the message of faith. Consequently, faith comes from hearing the message, and the message
is heard through the word of Christ (God) (Rom. 10:17, NIV). NT is the faith must be studied
consistently to be in the faith (2 Cor. 13:5). It is also that which Christians will defend against any
attack (Jude 3).
