The Great Commission of Jesus Himself teaches us to proclaim the Good News, to make converts and disciples, and water baptizing them who have received Jesus as Lord. Also, is the Abrahamic Covenant the same as the NC or not?True.
I understand this and thought you would take the argument in that direction. I also acknowledge my Baptist argument for the New Covenant is not a solid argument. I have admitted that for some time
I think the argument is a little more nuanced than this for Reformed Baptists. The 1689 Baptist Confession 7:3 says "This covenant is based on the eternal covenant transaction between the Father and the Son concerning the redemption of the elect". So a Reformed Baptist can say first and foremost it is something God does.
I agree with this point.
