Do Protestant Christians believe the 'new covenant' prophecy in Jeremiah 31 has come true?

### Introduction In the Christian New Testament, *The Epistle to the Hebrews* cites Jeremiah 31:33 to inaugurate a "new covenant". Jeremiah 31:33 and it's immediate context reads: > See, a time is coming—declares GOD—when I will make a new covenant > with the House of Israel and the House of Judah. > It will not be like > the covenant I made with their ancestors, when I took them by the hand > to lead them out of the land of Egypt, a covenant that they broke, > though I espoused them—declares GOD. > But such is the covenant I will > make with the House of Israel after these days—declares GOD: > **I will put My *Torah* into their inmost being and inscribe it upon their** > **hearts. Then I will be their God, and they shall be My people.** > **No longer will they need to teach one another** and say to one another, > “Heed GOD”; for all of them, **from the least of them to the greatest**, > **shall heed Me**—declares GOD. **For I will forgive their iniquities,** **And** > **remember their sins no more**. This "new covenant" in Jeremiah appears to involve the following: - The *Torah* is written on the hearts of Israel and Judah - Affirmation of Israel and Judah as God's people - A cessation of needing to teach each other to follow God - All of Israel and Judah (from the least to the greatest) will follow God - Forgiveness of their sins ### Question Do *Sola Scriptura*/Protestant Christians believe that this new covenant has taken effect? Do they believe only parts of the covenant are in effect? If so, which parts?
