Q. Your most recent post comparing the God of the OT and NT made me think of a question. What do you see as the relationship between the Mosaic covenants and the new covenant? As far as I can tell from Jeremiah, the new covenant has the same information, it is just that all the previous terms of the Biblical covenants were written on stone and scrolls, where in the new covenant, they will be written on one’s heart. Therefore the new covenant will be better, as we will want to do the stipulations in it.
I think this is basically right. The covenant with Moses had some things that I believe were identity markers for God’s people at the time, such as keeping kosher, observing certain days, etc. The New Testament makes clear that these are no longer obligations for followers of Jesus.
But certainly the ethical imperatives of the covenant, summed up by Jesus as “love the Lord your God with all your heart, and your neighbor as yourself,” remain. As you say, under the new covenant, we now want to fulfill them, as we are given new hearts. Our identity markers as covenant people are love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control—the fruit of the Spirit.
As I believe you’re saying, when seen from the perspective of the character and actions that God wanted to produce all along in His people, there is more continuity than discontinuity between the Mosaic covenant and the new covenant.
