You do understand that the New Covenant under which we live is promised in the OT and is a new, better and living covenant right?
How can you deny it on one hand and then supposedly embrace it on the other?
I do.
I do not reject that God interacts through covenants. I believe this obvious.
BUT I am not talking about biblical covenants. I am talking about Covenant Theology.
Scripture also talks about dispensations. By your criteria one must affirm Dispensationalism or reject Scripture.
Both Covenant Theology and Dispensationalism are frameworks developed within Calvinist circles to provide structure to the Economy of Salvation (Divine Economy).
I simply do not believe such a framework is necessary. Each emphasizes some aspect of Scripture (covenants or dispensations) while at best minimizing the other.
Also, we risk diminishing important periods in biblical history. The Dispensationalist may ignore the significance of a covenant to a specific people, but the Covenant theologian may minimize a dispensation where God withdraws or interacts in a different way under the same covenant).
I reject the idea we should look through Scripture and organize God's Words by importance. It is ALL important.
