Genesis 21:1-7 New Revised Standard Version (NRSV)
The Birth of Isaac
21 The Lord dealt with Sarah as he had said, and the Lord did for Sarah as he had promised. 2 Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him. 3 Abraham gave the name Isaac to his son whom Sarah bore him. 4 And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5 Abraham was a hundred years old when his son Isaac was born to him. 6 Now Sarah said, “God has brought laughter for me; everyone who hears will laugh with me.” 7 And she said, “Who would ever have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
Romans 6:1-11 New Revised Standard Version (NRSV)
Dying and Rising with Christ
6 What then are we to say? Should we continue in sin in order that grace may abound? 2 By no means! How can we who died to sin go on living in it? 3 Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 Therefore we have been buried with him by baptism into death, so that, just as Christ was raised from the dead by the glory of the Father, so we too might walk in newness of life.
5 For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his. 6 We know that our old self was crucified with him so that the body of sin might be destroyed, and we might no longer be enslaved to sin. 7 For whoever has died is freed from sin. 8 But if we have died with Christ, we believe that we will also live with him. 9 We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. 10 The death he died, he died to sin, once for all; but the life he lives, he lives to God. 11 So you also must consider yourselves dead to sin and alive to God in Christ Jesus.
