Being in Relationship With God

Genesis 17:1-14; 17-22, NRSV

1When Abram was ninety-nine years old, the Lord appeared to Abram, and said to him, “I am God Almighty; walk before me, and be blameless. 2And I will make my covenant between me and you, and will make you exceedingly numerous.” 3Then Abram fell on his face; and God said to him,
4“As for me, this is my covenant with you: You shall be the ancestor of a multitude of nations. 5No longer shall your name be Abram, but your name shall be Abraham; for I have made you the ancestor of a multitude of nations. 6I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you.
7I will establish my covenant between me and you, and your offspring after you throughout their generations, for an everlasting covenant, to be God to you and to your offspring after you. 8And I will give to you, and to your offspring after you, the land where you are now an alien, all the land of Canaan, for a perpetual holding; and I will be their God.” 9God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. 11You shall circumcise the flesh of your foreskins, and it shall be a sign of the covenant between me and you. 12Throughout your generations every male among you shall be circumcised when he is eight days old, including the slave born in your house and the one bought with your money from any foreigner who is not of your offspring. 13Both the slave born in your house and the one bought with your money must be circumcised. So shall my covenant be in your flesh an everlasting covenant. 14Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”
17Then Abraham fell on his face and laughed, and said to himself, “Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?” 18And Abraham said to God, “O that Ishmael might live in your sight!” 19God said, “No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. 20As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation. 21But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.” 22And when he had finished talking with him, God went up from Abraham.
