Jeremiah 31:31-34 (NKJV)
A New Covenant
31 “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah
Yes the old covenant of animal sacrifices was replaced with the blood of Christ in the New Covenant, so now Christ blood covers our sins instead of animals. But you can fight it all you want, but the New Covenant was made with Israel, not the Gentiles. We are simply grafted into Israel when we get saved.
Paul says Salvation is for everyone.
Romans 1:16(NKJV)
The Just Live by Faith
16 For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek.
So its clear there is one law we are to follow and there is no such thing as Jew command and Gentile commands, yet on this forum, people are quick to say .... well , the gentiles arent commanded to do so and so, when the bible clearly states we all have the same law in the new covenant.
Acts 15:20-21(NKJV)
20 but that we write to them to abstain from things polluted by idols, from sexual immorality, from things strangled, and from blood. 21 For Moses has had throughout many generations those who preach him in every city, being read in the synagogues every Sabbath.”
Acts 15 made it pretty clear that outside of the basic couple of things the gentiles were to refrain from as new followers of Christ, since these were big issues that they had as previously pagans, they will learn the rest as the continue to grow when they go to the synagogues every Saturday. Its no different than your job, in which on the first day you are given the basic rules and as time goes on, you will learn the rest of the rules.
