Genesis 18:1-15

And the LORD appeared to him near the oaks of Mamre, as he sat at the entrance of his tent in the heat of the day.

² He lifted up his eyes and looked, and see, three men were standing in front of him. When he saw them, he ran from the tent door to meet them and bowed himself to the ground

³ and said, “O Lord, if I have found favor in your sight, do not disregard your servant.

⁴ Let a little water be brought, and wash your feet, and rest yourselves under the tree,

⁵ while I bring a piece of bread, that you may refresh yourselves, and after that you may pass on- since you have visited your servant.” So they said, “Do as you have said.”

⁶ And Abraham went quickly into the tent to Sarah and said, “Now! Three seahs of fine flour! Knead it, and make cakes.”

⁷ And Abraham ran to the herd and took a calf, tender and exceptional, and gave it to a young man, who prepared it quickly.

⁸ Then he took curds and milk and the calf that he had prepared, and set it before them. And he stood beside them under the tree while they ate.

⁹ They said to him, “Where is Sarah your wife?” And he said, “She is in the tent.”

¹⁰ The LORD said, “I will surely return to you about this time next year, and Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him.

¹¹ Now Abraham and Sarah were old, by many years. The way of women had ceased to be with Sarah.

¹² So Sarah laughed to herself, saying, “After I am worn out, and my lord is old, shall I have this pleasure?”

¹³ The LORD said to Abraham, “Why did Sarah laugh and say, ‘Shall I really bear a child, now that I am old?’

¹⁴ Is anything too tough for the LORD? At the appointed time I will revisit you – about this time next year, and Sarah will have a son.”

¹⁵ But Sarah denied it, saying, “I did not laugh,” for she was afraid. He said, “No, you really did laugh.”

Honor and trust

It was not difficult for Abraham and his household to honor the three mysterious visitors who appeared near the oaks of Mamre. Hospitality was woven into the fabric of their life, and they recognized that this was no ordinary encounter. The presence of the LORD was unmistakable. What proved far more difficult was believing the message the LORD delivered. The promise that Sarah would bear a son within a year collided with everything she knew about herself. She had long accepted that “the way of women” had ceased. She had made peace with age and barrenness. She was content to cradle Ishmael, the child born through Hagar, and had quietly surrendered the hope of ever holding a child of her own flesh.

Sarah’s instinctive laughter at the promise is not foreign to the human heart. Before assigning blame to her, it is necessary to examine the patterns of thought that rise within every soul. The LORD promises a new birth to all who trust Him, a work of renewal that does not depend on youth, strength, or human possibility. Yet the inward reaction often resembles Sarah’s: a quiet, respectful posture on the outside, paired with an inward skepticism that wonders how such transformation could ever occur. Honor toward God is one thing; confidence in His power to create new life within is another.

Sarah described herself as “worn out,” a phrase used for garments that have been stretched thin, frayed, and exhausted by years of use.[1] Many hearts echo that sentiment. The soul can feel threadbare, weary from failure, disappointment, or long seasons of dryness. The promise of new birth is not distasteful; it simply feels unreachable. The mind rehearses limitations, and the heart whispers that renewal is for others, not for one who feels so spiritually tattered.

Yet the LORD does not measure His power by human frailty. He fulfills what He promises. Sarah and Abraham had to move beyond their self-assessment and trust the One who speaks life into what is dead. The same movement is required of all who hear the promise of new birth. Honor toward God must grow into reliance on His ability to accomplish the miraculous work He has planned.

LORD, our belief rests in the promise of new birth You have spoken. Strengthen the places where our unbelief still lingers. Grant us confidence in the astonishing future You intend to bring forth.
