Day 161 of the Women’s Bible Plan: Read Genesis 21:1-7 and reflect on the birth of Isaac, the child God had promised. Through Sarah’s experience of bearing a son in her old age, this devotional helps families see children as testimonies of God’s faithfulness, not as objects of parental control, comparison, anxiety, or personal achievement.
The arrival of a child often brings joy, responsibility, wonder, and many unknowns. For some families, a child is the answer to long years of prayer. For some parents, raising a child is filled with challenges, worries, waiting, and tears. We love our children deeply, yet it is easy to place our expectations, comparisons, fears, and unfinished dreams upon them.
Genesis 21:1-7 shows us a very special birth story: Isaac is born. This child did not come at the time people would have considered most reasonable, but at the time God had appointed. He was not received by human strength, but given according to God’s promise.
Sarah had laughed before. She had wondered, questioned, and doubted. Abraham and Sarah were both old, and from a human point of view, the possibility of bearing a son had long passed. Yet God did not forget what He had spoken. Isaac’s birth was not only the joy of one family; it was a testimony of God’s faithfulness.
Genesis 21:1-7 records that the Lord visited Sarah as He had said, and the Lord did unto Sarah as He had spoken. Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken. Abraham named the child Isaac and circumcised him on the eighth day, as God had commanded.
From the very beginning of this passage, Scripture repeatedly emphasizes one truth: God fulfilled what He had spoken. Isaac’s birth was not a coincidence, nor simply the success of human planning. It was God faithfully remembering and fulfilling His promise. After many years of waiting, Sarah conceived and bore a son, proving that God’s word had not failed and His timing had not been late.
From the perspective of parenting and family, Isaac’s birth reminds us that children are not first of all a source of parental achievement, a symbol of family status, or someone to be compared, controlled, or used to fill an empty place in a parent’s heart. A child is a life given by God, a sign of His faithfulness, and a precious trust placed in the hands of parents to love, nurture, guide, and bring before Him.
Sarah said, “God hath made me to laugh, so that all that hear will laugh with me.” The name Isaac itself carries the meaning of laughter. The laughter that once may have been unbelieving, bitter, or hidden was transformed by God’s faithfulness into grateful and joyful testimony. God can turn tears from years of waiting into joy within a family. He can turn human impossibility into a sign of His grace.
Today’s theme, “The Birth of Isaac: The Child of Promise,” invites us to reflect: How do we view children? Do we see them as our plan, our achievement, our continuation, or do we receive them as testimonies of God’s faithfulness and lives entrusted to us by Him? Whether we are raising children, walking with children, praying for children, or serving the next generation within our families and communities, God invites us to receive this calling with faith and gratitude.
1 Scripture says that the Lord visited Sarah as He had said and did unto Sarah as He had spoken. Have you ever experienced waiting, delay, or uncertainty in matters related to family or children? How does this passage remind you that God’s promise does not lose power just because time has passed?
2 Isaac’s birth was a testimony of God’s faithfulness, not only the joy of his parents. Are you sometimes tempted to see children as your achievement, your hope, or your source of security? Is God inviting you today to entrust children back to Him and acknowledge that their lives belong first to Him?
3 Sarah said, “God hath made me to laugh.” Are there situations in your family that once caused sighing, tears, or a sense of impossibility, yet later became testimonies of God’s grace? Even if you are still waiting now, are you willing to believe that God can still turn tears into joy?
As you read Genesis 21:1-7 today, do not only see the joy of Isaac’s birth. See also how God fulfilled His word after a long season of waiting. May this passage help us learn again in parenting and family life: children are not life projects for us to control, but precious lives entrusted by God and testimonies of His faithfulness.
Take a quiet breath before you begin. Bring your feelings about children, family, parenting, waiting, anxiety, and hope before the Lord, and let His Word meet you there.
“For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.”
— Genesis 21:2
21 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken.
2 For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
3 And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
4 And Abraham circumcised his son Isaac being eight days old, as God had commanded him.
5 And Abraham was an hundred years old, when his son Isaac was born unto him.
6 And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7 And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.
✨ Thank you for walking through today’s Scripture with us, dear sister.
Genesis 21:1-7 shows us that God visited Sarah as He had spoken and gave Isaac according to His promise. The birth of this child was not only joy in the household of Abraham and Sarah; it was a testimony of God’s faithfulness. Now, let us bring our families, children, parenting responsibilities, prayers in waiting, and hidden anxieties before the Lord.

Trusting That God Fulfills What He Has Spoken
Father, thank You for reminding me through Isaac’s birth that You are the faithful God who keeps covenant. Just as You visited Sarah according to Your word and fulfilled what You had spoken, You still watch over our families today with wisdom, timing, and love.
Lord, so often I look at circumstances, age, limitations, and visible realities, and my heart becomes anxious, doubtful, or discouraged. Help me not only to look at the difficulties before me, but to remember Your Word. Whether in my child’s growth, my family’s needs, the healing of relationships, or long-prayed prayers, give me faith to believe that Your timing is not late and Your promise does not fail. May I not rush You with fear, but wait for Your good will with trust. Amen.

Not Treating Children as My Own Achievement
Lord, Isaac was the child of promise, a life given by You. Please remind me that children are not trophies for parents, not objects of comparison, and not tools for fulfilling dreams I could not complete myself. Children belong first to You. They are lives entrusted to families to love, nurture, guide, and bless.
Please forgive me for the times I have turned anxiety into control, love into pressure, and expectation into burden. Help me see children with Your eyes—not only looking at grades, behavior, personality, or future success, but seeing lives made in Your image and in need of shepherding by grace. Teach me to have wisdom in discipline, patience in companionship, surrender in worry, and love that leads children toward You. Amen.

Letting the Family Become a Testimony of God’s Faithfulness
Father, Sarah said, “God hath made me to laugh, so that all that hear will laugh with me.” Lord, You can turn sighing into joy, long waiting into testimony, and impossibility into a sign of grace. Please work this way in my family also.
If my family is walking through pressure, conflict, waiting, or uncertainty, help me not to lose hope. If I have shed tears over children, marriage, parent-child relationships, or family responsibilities, comfort me personally and reveal Your grace in Your time. May my home not be a place that pursues outward success only, but a place where Your faithfulness is spoken of, Your mercy is experienced, love is learned, and hearts turn together toward You. Amen.

Praying for Children and Families
Compassionate God, I also pray for children and families around the world. I pray for children growing up in poverty, war, sickness, displacement, broken homes, and lack of care. I also pray for parents who carry overwhelming pressure, have little support, and bear responsibility alone. You know every child’s name, and You see every family’s tears.
Lord, protect children. Cover them in danger, provide for them in need, and comfort them in brokenness. Raise up compassionate people, families, churches, and resources to support the weak, walk with wounded families, and help parents have strength for their calling. May more children grow in love, may more families experience Your healing and faithfulness, and may this world learn to treasure life, protect the next generation, and receive children as precious gifts from You. Amen.
After reading Genesis 21:1-7, we see that Isaac’s birth was not merely a joyful family event. It was the fulfillment of what God had spoken. Sarah had waited long and once thought it impossible; but at the set time God had spoken of, He visited her, gave life, and turned sighing into laughter.
As we close this page and return to our family life, children’s growth will not always follow our plans, and parent-child relationships will not always be easy. We will worry, wait, make mistakes, and learn to release control. But remember this: children are not report cards for parents to prove themselves. They are lives entrusted by God and testimonies of His faithfulness and grace.
May today’s Scripture remind you to replace control with gratitude, anxiety with prayer, and comparison with trust. As you raise, accompany, pray for, and watch over the next generation, may you see more and more of God’s faithfulness, and may your family become a place that tells of His grace.
