Genesis 18:9-15
God’s promises stand firm despite human doubt because His power guarantees their fulfillment.
9 They asked him, “Where is Sarah, your wife?” He said, “There, in the tent.”
10 He said, “I will certainly return to you at about this time next year; and behold, Sarah your wife will have a son.” Sarah heard in the tent door, which was behind him.
11 Now Abraham and Sarah were old, well advanced in age. Sarah had passed the age of childbearing.
12 Sarah laughed within herself, saying, “After I have grown old will I have pleasure, my lord being old also?”
13 Yahweh said to Abraham, “Why did Sarah laugh, saying, ‘Will I really bear a child when I am old?’
14 Is anything too hard for Yahweh? At the set time I will return to you, when the season comes round, and Sarah will have a son.”
15 Then Sarah denied it, saying, “I didn’t laugh,” for she was afraid. He said, “No, but you did laugh.”
God’s promises stand firm despite human doubt because His power guarantees their fulfillment.
To reaffirm the promise of a son through Sarah and confront unbelief with God’s sovereign power.
