Key Verse: Genesis 17:1-2
"When 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, that I may make my covenant between me and you, and may multiply you greatly.’”
Genesis 17 is a pivotal chapter in the story of Abraham. Thirteen years have passed since the birth of Ishmael, and Abram is now 99 years old. He has waited decades for the promise of a son through Sarai, and at this point, it may have seemed impossible. But God appears to him again, reaffirming His covenant and introducing a new requirement—circumcision.
God Introduces Himself as "El Shaddai" (God Almighty)
For the first time in Scripture, God reveals Himself as El Shaddai, which means "God Almighty." This name emphasizes that nothing is impossible for Him. Abram had spent years trying to figure things out on his own, but now God reminds him that the promise does not depend on human ability, but on divine power.
God calls Abram to walk before Him and be blameless. This does not mean perfection, but wholehearted devotion and obedience. Abram had faltered in trusting God’s timing, but now God is asking him to fully surrender and walk in faith.
A New Name: Abram Becomes Abraham
God changes Abram’s name to Abraham, which means “father of many nations.” This is significant because Abraham still has no son with Sarai, yet God calls him what he will become. God’s promises are so sure that He speaks of them as if they are already fulfilled.
God also changes Sarai’s name to Sarah, meaning “princess.” This name signifies that she is not just the wife of Abraham, but the mother of kings and nations. Though she is 89 years old and barren, God confirms that she will give birth to a son.
The Covenant of Circumcision
God then gives Abraham a physical sign of the covenant—circumcision. Every male in his household, including himself, must be circumcised as an outward sign of their relationship with God. This act set Abraham’s descendants apart from the surrounding nations and symbolized a heart set apart for God.
Circumcision was a reminder that God’s people were to be holy, obedient, and different from the world. It was not just an external ritual but pointed to something deeper—the need for a circumcised heart, a heart fully devoted to God.
Later, in the New Testament, Paul explains that true circumcision is not of the flesh but of the heart (Romans 2:29). This foreshadows how Jesus would bring a new covenant, not based on physical rituals but on transformation through faith.
Abraham Laughs at God’s Promise
When God tells Abraham that Sarah will bear a son, he laughs. Not in mockery, but in disbelief—he is 99, and Sarah is 89. From a human perspective, it seems absurd. But God responds in Genesis 18:14, “Is anything too hard for the Lord?”
This is a powerful moment. God is not limited by human impossibility. What seems laughable to Abraham is completely possible for God. This is a reminder that God’s promises are not based on what we see, but on His power.
God tells Abraham that his son will be named Isaac, which means “he laughs.” This name would forever remind Abraham and Sarah that God turns doubt into joy.
What About Ishmael?
Abraham, still thinking practically, asks God to bless Ishmael, his son with Hagar. God does promise to bless Ishmael, making him into a great nation. However, the covenant will be fulfilled through Isaac, not Ishmael. God’s plan was always to bring the promised son through Sarah, not through human effort.
Abraham Obeys Immediately
After God speaks, Abraham does not hesitate—he circumcises himself, Ishmael, and every male in his household that very day. This shows his faith and obedience. Even though the promise had not yet been fulfilled, Abraham acted on God’s word.
Lessons from Genesis 17
God’s timing is perfect, even when it seems impossible. Abraham waited for years, but God’s promise did not fail. Even when circumstances seemed hopeless, God was still working.
God calls us to a life set apart. Circumcision was a physical sign of commitment to God, but today, He calls us to a heart that is fully devoted to Him.
Faith requires action. Abraham obeyed immediately. When God speaks, we must trust Him enough to respond. Delayed obedience is disobedience.
God’s power is greater than our doubts. Abraham laughed, but God’s response was clear: “Is anything too hard for the Lord?” Whatever seems impossible in your life, God is able to do more than you can imagine.
Are We Trusting God's Promises Even When They Seem Delayed?
Abraham waited decades for the promise. In the waiting, he made mistakes, doubted, and even tried to help God along. But in the end, God fulfilled His word in His way and in His time.
If you are waiting on a promise from God, remember that He is El Shaddai—God Almighty. His timing may not match yours, but He is never late. The question is—will you trust Him even when the promise seems impossible?
