Hi Titus! I wouldn’t disagree that God gave his covenant to Israel, and it was then fulfilled by Jesus, but I think, perhaps, we have different understandings of some terms. Jesus came and died that we might become part of God’s people, correct? In which case, would we not also be considered part of Israel? Additionally, Jesus came to fulfill the law of sin and death — would that then cause the entirety of the Mosaic covenant to be completed, or simply part of it? I’d be very interested to hear your thoughts!
