Covenant of Grace

Therefore Christ is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, now that He has died to redeem them from the transgressions committed under the first covenant.

What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise.

Because of this oath, Jesus has become the guarantee of a better covenant.

The Scripture foresaw that God would justify the Gentiles by faith, and foretold the gospel to Abraham: “All nations will be blessed through you.”

And He has qualified us as ministers of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.
