The New Testament in Prophecy
The whole notion that the New Testament does away with the Law is contrary to the prophecies of what the New Testament represents. It may be what Paul claims happened, but Paul's words cannot be accepted at odds with the prior Holy Scripture. Inspired scripture taught that the New Testament revitalizes the Law (given Moses):
“Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.” (Jeremiah 31:31–34, ESV. See also Exodus 20:6; Deuteronomy 5:10; Ezekiel 11:19-21)
Ezekiel, who lived around the same time as Jeremiah, adds that God will give a new spirit, and the Holy Spirit will cause believers to walk in God’s statutes and obey His rules.
26 And I have given to you a new heart, And a new spirit I give in your midst, And I have turned aside the heart of stone out of your flesh, And I have given to you a heart of flesh. 27 And My Spirit I give in your midst, And I have done this, so that in My statutes ye walk, And My judgments ye keep, and have done them. (Ezekiel 36:26-27 YLT.)
The New Covenant is a new heart of flesh on which is written His Law by the Spirit. Jeremiah and Ezekiel were written about 600 years before Christ, so everyone knew what “my Law” and "My statutes" meant. It is none other than the living oracles (as Stephen called them in Acts 7:38) given at Mt. Sinai by God through Moses.
Thus, instead of the Law being some horrible thing we must flee from, supposedly because it makes us a 'legalist' (Paulinists speaking again), the Law is always spoken everywhere else very highly:
It is love (John 15:10, 12-14), light and lamp (Proverbs 6:23; Psalm 119:105; Isaiah 8:20; Revelation 21:23, 22:5); life (Deuteronomy 4:1, 32:46-47; Proverbs 1:17, 8:33-36; Matthew 19:16,17); seed (Matthew 13:18-23), instructions (Isaiah 1:10; Exodus 16:4 24:12; Jeremiah 35:13; Job 22:22, 36:10; Psalm 78:1; Zephaniah 3:1-7; Malachi 2:1-9, Proverbs 1:2,3,7,8 4:1,2); law (Jeremiah 6:18-19; Zechariah 7:12; Deut 5:5 17:11, 27:1-3, 26, 30:10,14, 32:46,47; John 15:25; Acts 6:2-4,7 13:44,48,49, 28:23); commands, judgments, teachings & ways (Isaiah 2:3; Proverbs 5:12 7:2 8:10 1:8 4:2 3:1 6:20-23; Jeremiah 32:33; Deuteronomy 4:1; 2 Chronicles 15:1-7; Matthew 4:23 7:28,29 9:35 13:54 15:9 28:20; Acts 2:42 4:2 18:11); wisdom, and truth (Psalm 119:43,44,142 138:2; Proverbs 23:23; Malachi 2:6; 1 Kings 2:3-4; John 17:17, 18:37-38, 8:31-32; James 1:18, 21-23,25). It is the straight paths for our feet and a light to our way. (This list is taken from WholeBible.com.)
