I’m not sure I understand you. Are you referring to the covenant God made with Israel when He brought them out of Egypt? Or the new covenant in Christ’s blood which He made with His church?
.
The “New covenant” is the renewal of the original covenant that was repeatedly broken, as was prophesied by all of the major prophets.
A broken covenant must be renewed in blood; that renewal was Yeshua’s final task of his earthly ministry. That renewal was not with any “church,” but with his “assembly, the “lost sheep of the House of Israel,” (Ephraim) and those additional gentiles that sojourned with them.
Matthew 15:24 tells who Yeshua was sent to gather, to expand (not ‘build’) his assembly.
Yeshua had no church, his assembly is a mystical body that includes all of his elect, from Adam, to the end, not a building full of ‘treasures’ made with hands.
His first task was the lifting of Satan’s burden of the false torah preached and enforced by the Pharisees.
All of his miracles were performed to accomplish that task.
He took those false laws to the cross with him, ending that burden for his elect.
If you are drawn to him, you are one of those lost sheep, whether of genetic Ephraim, or of those that sojourn with him.
