The Lord covenanted with Abraham and Sarah that through them, the heir of worlds would come. In fact, he changed both of their names in light of his covenant promise, Abram to Abraham (father of many nations), and Sarai (princess) to Sarah (mother of many nations). Though only a minor change, God assured them that their seed would produce kings (v. 16; cf. v. 6), and both Abraham and Sarah laughed at the prospect that a ninety-nine-year-old man and a barren ninety-year-old woman would give birth to a child of promise who would save his people, and bless the families of the earth (Gen. 12.1-3).After angelic visitors came to Abraham and assured him that one year from their visit Sarah would bear a son, Sarah laughed in her heart. The Angel of the Lord, which the text declares to be a theophany (appearing) of the Lord himself (cf. 16.7), rebuked her reply, suggesting rhetorically, “Is anything too hard for the Lord?” This personal visit to Abraham and Sarah announces the fulfillment of his promise, that the time had come, and that he was capable of doing the impossible. Not aged parents, not a dead womb, not even disbelieving laughter can interfere with the covenant promise of God for those to whom he has granted his promise.The book of Hebrews summarizes the actions of Sarah as a faithful response to God’s promise. By faith she received power to conceive, even though she was well past the age of childbearing, for “she considered him faithful who had promised.” And, the account concludes, “Therefore from one man, and him as good as dead, were born descendants as many as the stars of heaven and as many as the innumerable grains of sand by the seashore” (Heb. 11.11-12). Sarah, through it all, considered the Lord faithful, and trusted him, even in light of the impossibility of her giving birth. She trusted in the God that can do the impossible among the absolutely unlikely.
Invocation: Our Prayer of Acclamation
Eternal God our Father, Abraham and Sarah clung to your covenant promise for a son even though they were long past the age of bearing children together. They trusted in you, and you fulfilled your promise to them, enabling them to give birth to Isaac, the child of the promise. Sarah counted you faithful in spite of the condition of her body, so help us to do the same as you continue to lead us into your will. In Christ’s name, amen.

Come then, Lord, and help your people, bought with the price of your own blood, and bring us with your saints to glory everlasting.

Affirmation from the Psalms
Remember the wondrous works that he has done, his miracles, and the judgments he uttered,  O offspring of Abraham, his servant, children of Jacob, his chosen ones!  He is the LORD our God; his judgments are in all the earth.  He remembers his covenant forever, the word that he commanded, for a thousand generations,  the covenant that he made with Abraham, his sworn promise to Isaac,  which he confirmed to Jacob as a statute, to Israel as an everlasting covenant,  saying, “To you I will give the land of Canaan as your portion for an inheritance.”
~ Psalm 105.5-11
