* You do not add new cloth to an old garment (Mt. 9:16).
* You do not put new wine in an old wineskin (Mt. 9:17).
* A faithful teacher recognizes the difference between the "old" and the "new" (Mt. 13:52).
* The Jews sacrificed animals, but Christ is our Sacrifice (Mt. 26:28).
* "Tongues" were not necessary for the Jew because they did not evangelize; "tongues" were for the Church Age (Mk. 16:17; 1 Cor. 12 - 14).
* The New Testament sums up all of the Law in a single commandment (Mt. 5:43-48; 7:12; 22:40; Rom. 13:8-10; 1 Thes. 3:11-13; 1 Tim. 1:5; 1 Jn. 3:23).
* The New Testament believer is indwelt by the Holy Spirit (Jn. 14:17).
* The fact that there is a New Testament (Heb. 9:15).
* Jesus has provided the Church with a "new and living way" (Heb. 10:12-20).
* In Christ, the members of His Body, the Church, are themselves new (2 Cor. 5:17).
Notice that in Christ, both Jew and Gentile cease to be identified with their "race," and become a new "race": Christians (Gal. 3:28). Today, we have three categories of people: Jews, Gentiles, and Christians. Prior to Acts 2, there were only two: Jews and Gentiles. When the Church is "caught up to meet the Lord in the air," there will, once again, be only Jews and Gentiles remaining.
The Law is the Old Covenant; the New Covenant of Grace came by Jesus Christ!
