And if God is the same yesterday, today and tomorrow then the old testament verse New Testament agreement is void.
God is the same and when he said that he would make a new covenant and that the old would not stand, and that the whole law was to be completed he did not change but kept his word. If the Old law remains then Christ died in vain.
A New covenant will be made:Jeremiah 31:31-34, Isaiah 28:10,13-19, Ezekiel 36:23-27,29-31
The Old Covenant will not stand:Isaiah 28:13-19
The New law will be written in their Hearts:Jeremiah 31:33-34, Ezekiel 36:26; Ezekiel 11:19
On a Tried stone will this Covenant be Made:Isaiah 28:16
This New Covenant will give the People a New Spirit:Ezekiel 36:26-27; Ezekiel 11:19
The New Covenant will be of the Promise of Faith:Isaiah 28:16
The Whole Covenant that was the Book of the Covenant would be Fulfilled:Isaiah 28:15,17
Matt 5:18
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Law completed
Christ Fulfilled the Whole Law of the Covenant:Hebrews 7:18-19,22; Luke 24:25-27, 44-49; Hebrews 9:14-15; Hebrews 8:4-13; Acts 13:38-41; Romans 10:4; Matt 5:17-20; John 19:30; Hebrews 12:2; 2 Timothy 3:15
Handwriting of Ordinances- Colossians 2:14; ,Hebrews 9:1; Hebrews 9:10,11,13,23-28; Ephesians 2:15
Law of Moses- Luke 24:25-27, 44-48; Acts 13:39; Acts 15:5; Acts 28:23; Mark 12:26-27
The Righteousness of the Lord is manifested without the Law of Moses
In the sight of the Lord no flesh is justified by the deeds of the law of moses(Romans 3:19,20,27) being witnessed by the law and the prophets, the righteousness of the lord is manifested without the law of moses(Romans 3:21,22,24,25) within the law of faith that we have received through christ(Romans 3:21,22,24,25,26,27) for if they which are of the Law be Heirs, then faith is made void and the promise of faith along with it(Romans 4:14,15).
Whosoever followeth the law of moses is a debtor to the whole law(Galatians 5:3,4;Galatians 3:10,12) and christ shall profit them nothing for he will become of no effect unto them who keep
the law of the covenant(Galatians 5:2,4;Galatians 3:11;Romans 3:19,20,27) There is no flesh justified by the works of the law of Moses(Galatians 2:16) if we now build again that which is of the law and keep it, that is to say put ourselves back into bondage, we become transgressors(Galatians 2:4,18) for if righteousness came by the law then Christ died in vain(Galatians 2:21).
The Old law is done as the Lord has commanded. We are now under the New law as he has commanded.
