The Old Testament reading is taken from the book of Genesis, chapter 17, verses 1-7 & 15-16
The covenant of circumcision
17 When Abram was ninety-nine years old, the Lord appeared to him and said, ‘I am God Almighty; walk before me faithfully and be blameless. 2 Then I will make my covenant between me and you and will greatly increase your numbers.’
3 Abram fell face down, and God said to him, 4 ‘As for me, this is my covenant with you: you will be the father of many nations. 5 No longer will you be called Abram; your name will be Abraham, for I have made you a father of many nations. 6 I will make you very fruitful; I will make nations of you, and kings will come from you. 7 I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you.
15 God also said to Abraham, ‘As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. 16 I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.’
This is the word of the of the Lord
®Thanks be to God
The Epistle is taken from Paul’s letter to the Romans, chapter 4, verses13-25
13 It was not through the law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith. 14 For if those who depend on the law are heirs, faith means nothing and the promise is worthless, 15 because the law brings wrath. And where there is no law there is no transgression.
16 Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring – not only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all. 17 As it is written: ‘I have made you a father of many nations.’He is our father in the sight of God, in whom he believed – the God who gives life to the dead and calls into being things that werenot.
18 Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, ‘So shall your offspring be.’ 19 Without weakening in his faith, he faced the fact that his body was as good as dead – since he was about a hundred years old – and that Sarah’s womb was also dead. 20 Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, 21 being fully persuaded that God had power to do what he had promised. 22 This is why ‘it was credited to him as righteousness.’ 23 The words ‘it was credited to him’ were written not for him alone, 24 but also for us, to whom God will credit righteousness – for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification.
