1. Carefully observe this interaction between Abram and God. Review your understanding of "righteous" and "justify." What is this covenant relationship?

After these things the word of Yahweh came to Abram in a vision, saying,
"Do not fear, Abram,
I am a shield to you;
Your reward shall be very great."
And Abram said, "O Lord Yahweh, what will You give me, as I go on being childless, and the heir of my house is Eliezer of Damascus?" And Abram said, "Since You have given no seed to me, behold, one born in my house is my heir." Then behold, the word of Yahweh came to him, saying, "This one will not be your heir; but one who will come forth from your own body, he shall be your heir." And He brought him outside and said, "Now look toward the heavens, and number the stars, if you are able to number them." And He said to him, "So shall your seed be." Then he believed in Yahweh; and He counted it to him as righteousness. (Gen 15:1-6, LSB)

And He said to him, "I am Yahweh who brought you out of Ur of the Chaldeans, to give you this land to possess it."
And he said, "O Lord Yahweh, how may I know that I will possess it?"
So He said to him, "Bring Me a three year old heifer, and a three year old female goat, and a three year old ram, and a turtledove, and a young pigeon." Then he brought all these to Him and split them into parts down the middle and laid each part opposite the other; but he did not split apart the birds. Then the birds of prey came down upon the carcasses, and Abram drove them away.
Now it happened that when the sun was going down, a deep sleep fell upon Abram; and behold, terror and great darkness fell upon him. Then God said to Abram, "Know for certain that your seed will be sojourners in a land that is not theirs, and they will be enslaved and mistreated four hundred years. But I will also judge the nation to whom they are enslaved, and afterward they will come out with many possessions. As for you, you shall go to your fathers in peace; you will be buried at a good old age. Then in the fourth generation they will return here, for the iniquity of the Amorite is not yet complete." Now it happened that the sun had set, and it was very dark, and behold, there appeared a smoking oven and a flaming torch which passed between these pieces. On that day Yahweh cut a covenant with Abram, saying,
"To your seed I have given this land,
From the river of Egypt as far as the great river, the river Euphrates: (Gen 15:7-18, LSB)

2. While God made a covenant with Abraham, what does the apostle Paul say to New Testament Believers? How can a sinful person be justified (proven right and acquitted of sin) before the holy God? Is there a covenant relationship with the New Testament Believer and God?

Just as Abraham believed God and it was counted to him as righteousness, so know that those who are of faith, those are sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, proclaimed the gospel beforehand to Abraham, saying, "All the nations will be blessed in you." So then those who are of faith are blessed with Abraham, the believer. (Gal 3:6-9, LSB)
