And no longer shall each one teach his neighbor and each his brother, saying, 'Know YHVH', for they shall all know me, from the least of them to the greatest, declares YHVH. For I will forgive their iniquity, and I will remember their sin no more.
Jeremiah 31:34

Denominations, missions, etc., are all proof that the New Covenant is not fully in force yet. As long as one person needs to teach another about God and his Law, the New Covenant is still waxing, but not full.

David's covenant didn't cancel Moses' which didn't cancel Abraham's which didn't cancel Noah's. No covenant annuls an older one. Neither does the New Covenant replace the Old. It expands it and restores it to its original purpose.
