In this episode of In the Garden, we explore Genesis 17 and the profound meaning of covenant obedience. God calls Abraham to a radical act: circumcision as the sign of His covenant (Genesis 17:10–11, 23–27). This physical mark was not just a ritual—it represented total surrender of self to God, beginning even with the body and extending to all of life.
Abraham had previously tried to fulfill God’s promise through human means by fathering Ishmael with Hagar (Genesis 16). Like Adam before him, Abraham momentarily placed human reasoning above God’s word. Yet God calls him back into covenant faithfulness, demonstrating that obedience cannot be partial or delayed. Genesis emphasizes that Abraham obeyed “that very day” (Genesis 17:23, 26), at ninety-nine years old, along with his son Ishmael, who was thirteen.
Even though Ishmael was born outside the covenant line God intended to establish through Isaac (Genesis 17:19), Abraham’s love for Ishmael is evident:
“Oh that Ishmael might live before you!” (Genesis 17:18)
And God blesses Ishmael as well, promising to make him a great nation. His inclusion reminds us that God’s love and blessing extend beyond the covenant line, even to those born through human missteps.
The act of circumcision foreshadows a deeper spiritual truth. God later calls His people to circumcise the heart:
“Circumcise therefore the foreskin of your heart, and be no longer stubborn.” (Deuteronomy 10:16)
Paul reinforces this in the New Testament, highlighting that covenant obedience requires faith and total commitment:
“Present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.” (Romans 12:1)
Jesus brings this principle to its fullest expression:
“If your right hand causes you to sin, cut it off… If your right eye causes you to sin, tear it out.” (Matthew 5:29–30)
He teaches that no part of our lives is neutral—our hands, our minds, our bodies, and our choices are all under God’s authority.
Through Abraham and Ishmael, we see that God’s covenant requires immediate, costly, whole-life obedience, yet His love and blessing are never limited by our mistakes. Circumcision points forward to baptism and the call to offer our entire selves to God, marking us not only physically or ritually, but spiritually as His children.
