Isaac and Rebekah – Living Between Promise and Fulfilment

(Genesis 21–27)

Isaac and Rebekah are shaped by promises made a generation before them and by a future that will be carried forward through their children. They show us both the quiet faithfulness and the hidden fractures that can exist within a believing family.

Isaac – The Child of Promise

Isaac is the long-awaited son of Abraham and Sarah, born when hope seemed impossible (Gen. 21:1–7). His very existence testifies to God’s faithfulness. Yet Isaac’s life is largely lived in the shadow of his father’s dramatic journey of faith.

Isaac appears less as a man of bold initiative and more as a steady, quiet, peaceful figure. He reopens the wells his father had dug, rather than striking out in new directions (Gen. 26:18). This quiet continuity matters. God’s promises are preserved not only by great risk-takers, but also by those who faithfully maintain what has been entrusted to them.

Isaac and the Near-Sacrifice

The defining moment of Isaac’s early life is what has been called ‘the binding on Mount Moriah’ (Gen. 22) in which Abraham feels God tells him to sacrifice Isaac. Though the focus in this story is on Abraham’s faith, Isaac is not a passive child. He carries the wood, asks the crucial question, and submits to his father’s obedience.

This event leaves a deep mark on his story. Isaac is a son who is, in a sense, given back from death (Heb. 11:17–19), pointing ahead to God’s own provision of a Son. Isaac’s life thereafter carries the weight of having been spared by grace.

Rebekah – Chosen and Willing

Rebekah enters the story as a young woman who responds generously and decisively to God’s unfolding plan (Gen. 24). She shows kindness to Abraham’s servant and his camels, and she willingly leaves her family to journey into the unknown.

Rebekah’s story reminds us that God’s purposes often advance through courageous decisions made in ordinary moments. Her ‘I will go’ (Gen. 24:58) echoes the faith of Abraham himself.

A Marriage Marked by Prayer and Pain

Isaac and Rebekah’s marriage begins with tenderness and comfort after loss (Gen. 24:67), but it is not free from struggle. Rebekah is barren for many years, and Isaac prays earnestly for her (Gen. 25:21). God answers, but the pregnancy is difficult, foreshadowing conflict to come.

God reveals that the twins within her womb represent two nations, and that the older will serve the younger (Gen. 25:23). From the beginning, this family lives with a divine promise that overturns human expectation, but also with the potential of conflict.

Favouritism and Family Division

As the children grow, Isaac favours Esau, while Rebekah favours Jacob (Gen. 25:28). This divided loyalty fractures the family. Later, Rebekah orchestrates Jacob’s deception of Isaac to secure the blessing (Gen. 27).

Rebekah acts to fulfil what she believes is God’s purpose, but she does so through manipulation rather than trust. Isaac, meanwhile, clings to his preference for Esau despite God’s earlier word. Both parents fall short, one through passivity, the other through control.

The result is lasting damage: Jacob flees, Esau is embittered, and Rebekah never sees her favourite son again.

God’s Faithfulness Through Human Weakness

The story of Isaac and Rebekah shows how God’s promises move forward even through flawed relationships and poor choices. God remains faithful, not because the family gets everything right, but because his purposes are larger than their failures.

Isaac eventually affirms Jacob’s blessing knowingly (Gen. 28:1–4), showing a late but genuine alignment with God’s plan.

4. Trust God’s promises without manipulation.
   Rebekah’s story warns us against trying to force God’s purposes through control.
5. God remains faithful despite human failure.
   The covenant continues, not because Isaac and Rebekah are perfect, but because God is.
