Signpost for Sunday 18th June 2017 (11th in Ordinary Time): Genesis 18:1-15, 21:1-7; Psalm 116:1, 10-17; Romans 5:1-8; Matthew 9:35 – 10:23.
How good it is to get back to the Genesis narratives. Today we have the Yahwist’s account of the announcement of Isaac’s birth, which in some respects is similar to the Priestly writer’s version in chapter 17. Both emphasise the tension between God’s promise of an heir and its fulfilment, in that both Abraham and Sarah are well beyond the age for child-bearing.
Today Sarah overhears the promise made to Abraham and laughs. She laughs to herself but God is not too pleased and chides her (through Abraham, not directly) for not understanding that there is nothing too wonderful for the Lord.
In the preceding chapter it is Abraham who laughs. The incredibly learned 17th century commentator, Matthew Henry, has it that Abraham’s laughter arises from great humility (he falls on his face) and great joy, but Sarah’s laughter is from doubt and mistrust. Although God does not rebuke Abraham as he does Sarah, the context in each version seems to allow the presumption that both of them had their “Yeah, right!” moment. However, Paul, using Abraham as the example in his dissertation on righteousness through faith in Romans 4, tells us that “He did not weaken in faith when he considered his own body, which was already as good as dead… No distrust made him waiver concerning the promise of God …”
Isaac, the second of the great patriarchs, is born and Sarah laughs again (21:6-7), this time in great joy and wonderment for herself and for “everyone who hears”. His name, given to him by God (17:19), means “He Laughs”. Joy is the proper response to the beginning of the creation of that great Nation of which we are now part.
