Under the new covenant, what does God promise to do?

Answer

"I will put My law in their inward parts, and write it in their hearts." Jer. 31: 33.
NOTE-The new covenant is an arrangement for bringing man again into harmony with the divine
will, and placing him where he can keep God's law. Its "better promises" bring forgiveness of sins, grace to
renew the heart, and power to obey the law of God. The dissolution of the old covenant and the making of
the new in no wise abrogated the law of God.

To whom does the \"seed\" in these promises refer?
Whose voice had more weight with Saul than had the commandment of God?
And how may we know that we love the brethren?
To whom does vengeance belong?
How enduring did He say the law is?
Under whose influence are the nations to be assembled?
What did the prophet Isaiah predict of Christ?
