Genesis 17:5-16

⁵ No longer will your name be called simply Abram, but your name will be Abraham, for I have made you the father of a noisy crowd of nations.

⁶ I will make you exceedingly productive, and I will make you into nations, and kings shall issue from you.

⁷ And I will institute my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be your personal God and to your offspring after you.

⁸ And I will give to you and to your offspring after you the land of your travels, all the land of Canaan, for an everlasting possession, and I will be their personal God.”

⁹ And God said to Abraham, “As for you, you will keep my covenant, you and your offspring after you throughout their generations.

¹⁰ This is my covenant, which you will abide by, between me and you and your offspring after you: Every male among you shall be circumcised.

¹¹ You all will be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you all.

¹² He who is eight days old among you will be circumcised. Every male throughout your generations, whether born in your house or bought with your money from any outsider who is not of your offspring,

¹³ both he who is born in your house and he who is bought with your money, will surely be circumcised. So shall my covenant be in your flesh an everlasting covenant.

¹⁴ Any uncircumcised male who is not circumcised in the flesh of his foreskin, that soul will be cut off from his people by death; he has broken my covenant.”

¹⁵ And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah.

¹⁶ I will bless her, and what is more, I will actually give you a son by her. I will bless her, and she shall become nations; kings of peoples shall come from her.” _________________________________________

New

From the vastness of eternity, God steps once more into the unfolding story of Abraham and Sarah. Their lives appear small on the surface—an aging couple in an obscure land—but God’s intention for them is anything but small. He marks the turning point of their future by giving them new names. These names are not cosmetic changes or symbolic gestures; they announce the roles they will play in the world God is shaping. Their identities are now tied to a future in which nations, tribes, and kings will trace their origins back to them. What begins as a family becomes a multitude, a noisy and diverse assembly of peoples spread across the earth.

Yet the promise is not merely about influence or legacy. God binds Himself to Abraham and Sarah in a personal way. The relationship is not distant or abstract. It is covenantal—rooted in commitment, loyalty, and shared responsibility. Covenant is the word Scripture uses to describe the bond between God and His people, a bond in which God pledges His faithfulness and protection, and His people pledge obedience and trust. It is relational and moral, intimate and binding.

To seal this covenant, God gives a physical sign: circumcision. Though it may appear harsh or primitive to modern eyes, it carried profound meaning in its original context. It marked the body in a way that symbolized belonging, identity, and continuity. It represented the passing down of the covenant from father to son, generation after generation. The sign was placed at the very point of human reproduction, emphasizing that the relationship with God was not merely individual but communal and enduring. It carried both privilege and obligation, reminding every descendant of Abraham that covenant life involved both rights and responsibilities.

In the new covenant established through Christ, the corresponding sign is believer’s baptism. Baptism does not mirror circumcision in form, but it mirrors it in meaning. It symbolizes the cutting away of the old life dominated by the flesh and the entrance into new life through the death and resurrection of Jesus. Colossians 2:11–17 explains this connection clearly: baptism marks participation in Christ’s victory, the forgiveness of sins, and the beginning of a transformed life. It is the sign of belonging to the people of God in the age of the gospel.

LORD, we accept our new names and the new sign, recognizing the relationship, rights, and responsibilities implied by it.
