The faith of Abraham and Sarah is a central theme in the biblical narrative, illustrating profound trust and obedience to God's promises. Their account is primarily found in the Book of Genesis, with further reflections in the New Testament, highlighting their significance in the history of salvation.

Abraham's Call and Promise

Abraham, originally named Abram, is introduced in Genesis 11:27-32. His journey of faith begins in Genesis 12:1-3, where God calls him to leave his homeland and promises to make him a great nation: "Go from your country, your people and your father's household to the land I will show you. I will make you into a great nation, and I will bless you" (Genesis 12:1-2). Abraham's response to God's call is immediate and obedient, demonstrating his faith as he departs with his wife, Sarai, and his nephew, Lot, without knowing their destination.

The Covenant and the Promise of a Son

God's covenant with Abraham is a pivotal moment in the biblical narrative. In Genesis 15, God reassures Abraham of His promise, despite Abraham's childlessness: "Look now at the heavens and count the stars, if you are able... So shall your offspring be" (Genesis 15:5). Abraham's belief in God's promise is counted to him as righteousness (Genesis 15:6), underscoring the foundational role of faith.

The promise of a son is reiterated in Genesis 17, where God changes Abram's name to Abraham, meaning "father of many nations," and Sarai's name to Sarah. Despite their advanced age, God promises that Sarah will bear a son, Isaac, through whom the covenant will continue: "I will bless her and will surely give you a son by her" (Genesis 17:16).

Sarah's Faith and Laughter

Sarah's journey of faith is marked by both doubt and belief. Initially, she laughs at the prospect of bearing a child in her old age (Genesis 18:12), yet her faith ultimately prevails. Hebrews 11:11 commends her faith: "By faith Sarah herself received power to conceive, even when she was past the age, since she considered Him faithful who had promised" .

The Testing of Abraham

The ultimate test of Abraham's faith occurs in Genesis 22, where God commands him to sacrifice Isaac. Abraham's willingness to obey, even in this heart-wrenching command, exemplifies his unwavering trust in God. As he prepares to sacrifice his son, God intervenes, providing a ram as a substitute: "Do not lay a hand on the boy... Now I know that you fear God, because you have not withheld from Me your son, your only son" (Genesis 22:12). This event foreshadows the sacrificial love of God in the New Testament.

New Testament Reflections

The New Testament frequently references the faith of Abraham and Sarah, emphasizing their role as exemplars of faith. Romans 4:3-5 highlights Abraham's faith as the basis for righteousness: "Abraham believed God, and it was credited to him as righteousness" . James 2:21-23 underscores the active nature of Abraham's faith, demonstrated through his works.

In Galatians 4:22-31, Paul uses the account of Sarah and Hagar to illustrate the difference between living under the law and living by faith. Sarah, the free woman, represents the covenant of grace and the promise fulfilled through faith.

Legacy of Faith

The faith of Abraham and Sarah is foundational to the Judeo-Christian tradition, symbolizing trust in God's promises and the righteousness that comes through faith. Their account is a testament to the power of faith to transcend human limitations and fulfill divine purposes.
