JMHO & YMMV
For me the basic Covenant in the New Testament revolves around Jesus reduction of the vast host of Laws in the OT to two, and in the fact that the Covenant is in reality, Bilateral.
John 3:16
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
There is no contract as seen in the OT.
The OT contract is between GOD and a people. It seperates that People from all others. The Covenant in the NT however is between God and the individual, a personal relationship. It is not with a people, it is not with a place, it is not even with a religion or sect.
As I read John 3:16, it says quite clearly that if you believe in GOD (some Christians try to make the word HIM in the verse point only to Jesus, but that falls apart unless Jesus is a seperate entity than GOD), then you will have everlasting life.
So, you will not find the mass meeting, the voting, the sign on the dotted line Covenant in the NT. It is simply not required. The NT Covenant is between YOU, the very individual YOU, and GOD. If you believe in GOD, then you fulfill your side of the contract.
The LAWs mentioned in the NT boil down to two. The first is what is needed for you to fulfill your half of the Covenant,
"Thou shalt love the Lord thy God". The second is how you should lead your life and exist in the kinship of man,
"Thou shalt love thy neighbor as thyself".
