Jeremiah 3:14-17 proves the 10 commandments were to be abolished when Christ came.
"'Return, O faithless sons,' declares the Lord; 'For I am a master to you, And I will take you one from a city and two from a family, And I will bring you to Zion.' "Then I will give you shepherds after My own heart, who will feed you on knowledge and understanding. "It shall be in those days when you are multiplied and increased in the land," declares the Lord, "they will no longer say, 'The ark of the covenant of the Lord.' And it will not come to mind, nor will they remember it, nor will they miss it, nor will it be made again. "At that time they will call Jerusalem 'The Throne of the Lord,' and all the nations will be gathered to it, to Jerusalem, for the name of the Lord; nor will they walk anymore after the stubbornness of their evil heart. " (Jeremiah 3:14-17)
This verse is a messianic prophecy fulfilled at the cross.
Jer 3:14-17, Jeremiah is speaking to backsliding Israel who will come back. God will give her shepherds according to His own heart who will feed her with knowledge and understanding (v. 15). As a result of this good teaching, people will multiply "in those days" (v. 16) and will say "no more, 'The ark of the covenant'" (v. 16). In fact, it will not even come to mind, be remembered, visited nor made any more (ibid.). Jeremiah is speaking of this in an approved way, contextually. What was in the ark of the covenant? The 10 Commandments correct? The 10 Commandments were the covenant (Deut. 4:13; 9:9; 9:11) and the ark contained them (1 Kin. 8:21). Now if the "ark" doesn't come to mind, is not visited or "made" any more, then that which is in the ark is not "made" any more either. Do you see my point? Further, Jeremiah tells us when the ark will not be remembered or visited or made in 3:17, "At THAT TIME (what time?) Jerusalem shall be called the Throne of the Lord, and all the nations shall be gathered to it. . .No more shall they follow the dictates of their evil hearts." When was Jerusalem the "Throne of the Lord" and when did "all nations gather to it" and when did Israel stop following the dictates of their heart? Was it not when God made a new covenant (Jer. 31:31-34) which was "not according" to the first covenant (i.e., 10 comm)? Was Jerusalem not the throne when the law came from there, "For out of Zion shall go forth the law, and the word of the Lord from Jerusalem. He shall Judge between the nations. . ." (Is. 2:3, 4). The first covenant came from Sinai the second came from Jerusalem. This is a "Pentecost pointer" as I believe Foy Wallace would once express. All of this tells us that the 10 commandment Covenant was abolished and not given to the church. It doesn't' enter our mind because we are not under it.
