Genesis 12:1-3 (New Revised Standard Version)
Now the Lord said to Abram, "Go from your country and your kindred and your father's house to the land that I will show you. I will make of you a great nation, and I will bless you, and make your name great, so that you will be a blessing. I will bless those who bless you, and the one who curses you I will curse; and in you all the families of the earth shall be blessed."
Romans 3:28-31 (New Revised Standard Version)
For we hold that a person is justified by faith apart from works prescribed by the law. Or is God the God of Jews only? Is he not the God of Gentiles also? Yes, of Gentiles also, since God is one; and he will justify the circumcised on the ground of faith and the uncircumcised through that same faith. Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
