What is New Testament theology?

Answer

New Testament theology involves studying what God has revealed about Himself in the New Testament. It organizes the various truths found in the New Testament books about God in a systematic way. The New Testament reveals the fulfillment of Old Testament prophecies about the Messiah (Isaiah 9), the rejection of the Messiah by Israel, the fulfillment of the Law, the establishment of the New Testament church (the body of Christ), the era of the church, the gospel of Jesus Christ, and guidance for believers in Jesus Christ.

The term “new covenant” (or “new testament”) was spoken by Christ during the Last Supper “Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.”, (Luke 22:20). Paul referred to the new covenant as the essence of the ministry to which he was called “who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.”, (2 Corinthians 3:6). The Old Testament records the calling and history of the Jewish nation, including the Mosaic Law, the Old Covenant that bound Israel for many years. The New Testament addresses the history and application of Christ’s redemption from the Law (Galatians 4:4-5), a redemption He provided through His death on the cross “In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;”, (Ephesians 1:7). As the New Covenant, it surpasses the Old “But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.”, Need a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises. », (Hebrews 8:6,13) «In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.», (Hebrews 8:6,13).

Theology is the study of the doctrines of the Bible, following the progressive revelation that God made to man from the beginning of time to the end of the book of Revelation. New Testament theology primarily deals with the study of Christology, ecclesiology, and soteriology. Furthermore, it enhances our understanding of eschatology, pneumatology, angelology, hamartiology, and other fields of doctrine.
