The New Testament of the Bible literally means “The New Covenant.” The word covenant means an arrangement made by one party, which another party involved could accept or reject but could not altar. We can accept or reject Jesus, but we can’t change or altar who He is, or what He accomplished. Religions try. People try. But it doesn’t change a thing.
The whole second half of the Bible teaches us about the new covenant given to us in Jesus. The Old Testament primarily records God’s dealings with Israel on the basis of the covenant given through Moses, while the New Testament describes the new arrangement of God with men through Christ on the basis of the New Covenant. The Old Covenant revealed the holiness of God in the righteous standard of the law and promised a coming Redeemer; the New Covenant shows the holiness of God in His righteous Son. The New Testament, then, contains those writings that reveal the content of this New Covenant
The message of the New Testament Centers on:
Thus the central theme of the New Testament is salvation. The Gospels introduce the Savior. The book called Acts describes the spread of the good news about His salvation. The letters (Romans-Jude) give details of the blessings of that salvation (and the practical application of Christian doctrine to life situations) , and Revelation describes the ultimate triumph of Jesus Christ and His people in the future.
We are now under the New Covenant of Jesus Christ who brings us from glory to glory each day through His unwavering grace. We are a chosen people belonging to God who called us out of a darkness into His wonderful light. We must declare His praises! (see 1Peter2:9) We are no longer at sin’s every beck and call. We get included in Christ’s sin conquering death and we also get included in His life-saving resurrection.
When Jesus died, He took sin down with Him, but alive He brings God down to us
From now on, think of it this way: Sin speaks a dead language that means nothing to you; God speaks your mother tongue, and you hang on every word. Sin doesn’t get a vote. You are dead to sin and alive to God. THAT’s what Jesus did. See Romans 6:1-23 MSG.
What will you do then with this Jesus? Accept or reject Him?
