We ARE in covenant, covenant with Christ, the new covenant in His blood.
It is similar to Yeshuas parable of the man who built on sand.
The *rock* is Jesus*.
1 Corinthians 10:4 For I do not want you to be unaware, brothers, that our fathers were all under the cloud, and all passed through the sea, and all were baptized into Moses in the cloud and in the sea, and all ate the same spiritual food, and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ.
>> “We ARE in covenant, covenant with Christ, the new covenant in His blood.” <<
.
Only if we “endure to the end.”
And that is the Renewed covenant in his blood. The same covenant with the same people and the same outcome, but now assured by the acceptable sacrifice.
One can break covenant, if one is willing to pay the price. Yeshua says many will do that.
