Genesis 15:1-6, 21:1-3; Psalm 104 (105):1 -6. 8-9; Hebrews 11:8,11 -12, 17 -19; Luke 2:22-40
God responds to Abram’s concern at his lack of heirs by promising him countless descendants. Even before male circumcision became a sign of this covenant, Abram was held righteous because he trusted in the Lord’s promise. Such was his faith that he travelled to a new land, and believed God’s promise of a son even in his old age. Sarah named their son Isaac, meaning “he who laughed”: Sarah had laughed at God’s promise that she would bear a son – now she perhaps feels the laugh is on her, caring for a new-born child in her nineties.
The psalm praises God’s goodness to his people, recounting His promises and care for them.
The letter to the Hebrews describes how Abraham’s faith was strong enough for the supreme test: would he sacrifice his son – his only son – to God? Just as God sacrificed his only son on the Cross to show how much he loves us.
Luke’s description of the consecration to God of Jesus, as Mary’s first-born son, links Jesus’ birth to God’s promises: the promised redeemer has come, and Abraham’s descendants in faith will indeed be as numerous as the stars. But God is always faithful to his promises and, in his justice, innermost thoughts will be revealed.
Psalm Response: He, the Lord, is our God. He remembers his covenant for ever.
