I. Background and Calling (Genesis 11–12)
Who he was
- Born Abram in Ur of the Chaldeans, a sophisticated Mesopotamian city
- Son of Terah, married to Sarai (later Sarah), who was barren
- Part of a polytheistic culture — his calling was a radical departure from everything familiar
The initial call (Genesis 12:1–3)
- God commands him to leave his country, his people, and his father’s household
- Promise given: a great nation, a great name, blessing to all peoples through him
- No destination given — he was to go to a land God would show him
II. Successes of Faith
1. Leaving Ur — the foundational act (Genesis 12:1–4)
- Left at 75 years old with no map, no guarantee, no explanation beyond God’s word
- Hebrews 11:8 says he “went, not knowing where he was going”
- The New Testament holds this up as the defining moment of his faith
2. Separating from Lot in peace (Genesis 13)
- When conflict arose between their herdsmen, Abram let Lot choose first
- Gave up the right of the elder, trusting God to provide
- Immediately after, God reaffirmed the land promise — faith honored
3. Rescuing Lot and refusing the king’s reward (Genesis 14)
- Assembled 318 trained men and defeated a coalition of four kings to rescue his nephew
- Refused to take any plunder from the king of Sodom — “not a thread or sandal strap”
- Did not want anyone to say a pagan king had made him rich
4. Believing God’s promise of a son (Genesis 15)
- God takes him outside and says: count the stars — so shall your offspring be
- Romans 4:20–21 says he “did not waver in unbelief” but was “fully convinced”
- God counted this faith as righteousness — the theological cornerstone of Paul’s entire argument in Romans and Galatians
5. Interceding for Sodom (Genesis 18)
- One of the most remarkable prayers in Scripture — bold, persistent, respectful
- Negotiated God down from 50 righteous to 10 before stopping
- Shows mature faith that understood God’s justice and mercy simultaneously
6. Offering Isaac on Mount Moriah (Genesis 22)
- The supreme test — commanded to sacrifice the very son through whom all promises were to come
- Hebrews 11:17–19 says he reasoned God could raise Isaac from the dead
- Obeyed without recorded argument or delay — rose early the next morning
- God stopped him and provided the ram — “the LORD will provide” (Jehovah Jireh)
- Called the friend of God (James 2:23); this moment sealed his legacy
III. Failures of Faith
1. The Egypt deception — Sarah as his sister (Genesis 12:10–20)
- Famine came and Abram went to Egypt without recorded consultation with God
- Told Sarai to say she was his sister, fearing the Egyptians would kill him for her
- Pharaoh took Sarah into his household; God afflicted Pharaoh with plagues
- Abram was rebuked by a pagan king — a humiliating reversal
- Fear drove him to sacrifice his wife’s honor to protect himself
2. Hagar and Ishmael — taking matters into his own hands (Genesis 16)
- Ten years had passed since the promise with no son
- Sarai proposed using her Egyptian servant Hagar as a surrogate — a culturally accepted practice
- Abram agreed without seeking God
- Result: Hagar conceived, despised Sarai, was mistreated and fled
- Ishmael was born — and the conflict between his descendants and Isaac’s echoes through history to this day
- This is the classic pattern of engineering a solution rather than waiting for God
3. The Egypt deception — repeated in Gerar (Genesis 20)
- Years later, same failure — told King Abimelech that Sarah was his sister
- More remarkable because by this point he had walked with God for decades and had seen God’s faithfulness repeatedly
- Abimelech also rebuked him; Abraham’s excuse was weak (“she is my half-sister”)
- Shows that old patterns of fear can resurface even in mature faith
4. Laughing at the promise (Genesis 17:17)
- When God told him Sarah would bear a son, Abraham fell on his face — and laughed
- Said in his heart: “Shall a child be born to a man who is a hundred years old?”
- A moment of doubt buried in the text, easily overlooked
- Sarah also laughed (Genesis 18:12) — then denied it when confronted
IV. What His Life Teaches About Faith
- Faith is a journey, not a single moment. Abraham’s greatest act (Genesis 22) came decades after his calling. The failures were part of the formation.
- The same fears recur. He lied about Sarah twice, years apart. Faith doesn’t eliminate weakness permanently — it requires continual recommitment.
- God works despite the failures. Ishmael was not the plan, but God blessed him too (Genesis 17:20). The deceptions could have derailed everything, but God protected the promise even when Abraham didn’t.
- Waiting is the hardest part. Nearly every failure stems from impatience — moving ahead of God’s timing rather than outright rebellion.
- He is called righteous, not perfect. Romans 4 holds Abraham up as the model of faith-based righteousness precisely because his record is mixed. The righteousness was credited, not earned.
