Day 10 of the Women’s Bible Plan: Read Genesis 21:1–7 and reflect on how God fulfilled His word in His appointed time. Through Sarah giving birth to Isaac, this devotional helps women see that God does not forget His promises. Even when the waiting feels long, the answer delayed, and hope almost impossible, God remains faithful to His word and His timing.
Some seasons of waiting last for a year or two. Others stretch so long that we almost stop daring to speak about them. Sarah’s life was marked by a long season of waiting. She followed Abraham away from her homeland into the unknown. She experienced fear, weakness, disappointment, and the painful reality of barrenness. She even laughed when she first heard God’s promise, because the promise seemed far beyond what human eyes could believe.
But God had not forgotten.
Genesis 21:1–7 shows us that the Lord visited Sarah as He had said, and did unto Sarah as He had spoken. Isaac’s birth was not only the birth of a child; it was a sign of God’s faithfulness. The human body grows weak, faith can tremble, and tears may gather over many years—but the word of God does not fail. He may not fulfill His promise according to our expected schedule, but He always fulfills it according to His appointed time.
JANUARY 10 / Day 10
In today’s Scripture, the Lord visits Sarah as He had said and fulfills what He had promised. Sarah conceives and bears Abraham a son in his old age, at the set time of which God had spoken. The child is named Isaac, a name connected with laughter. What was once a laugh of disbelief becomes a testimony of grace-filled joy.
This short passage is filled with comfort. It reminds us that God is not only the God who gives promises from afar; He is also the God who fulfills His word when the appointed time has come. Sarah’s story tells us that waiting does not mean God has forgotten, and delay does not mean God has failed. God’s silence is not His absence, and His timing is never random.
Today’s theme is “Sarah: The Birth of Isaac,” and our focus is to see that God fulfills His word in His appointed time. Perhaps you, too, are waiting for an answer, a turning point, a healing, a restored relationship, or a breakthrough in life. May Sarah’s story remind you that the God you trust is the God who remembers, the God who acts according to His word, and the God who can turn tears into laughter.
1 Sarah waited a long time for God’s promise to be fulfilled. Is there a long waiting season in your life that has moved from expectation to weariness, or even from hope to hesitation? How does today’s passage remind you that God still remembers what He has spoken?
2 Scripture says that Sarah gave birth “at the set time of which God had spoken.” Have you ever felt anxious, disappointed, or doubtful because God did not work according to your timeline? Are you willing to surrender your schedule to Him again?
3 Sarah said, “God hath made me to laugh.” Is there an area of your life where you once thought only regret remained, but where you still want to believe that God can bring new joy and testimony?
As you read Genesis 21:1–7 today, do not only look at the result. Look also at the faithfulness of God through the long years of waiting. Isaac in Sarah’s arms was more than a child; he was a reminder that God is responsible for what He has spoken, and that His appointed time carries His perfect wisdom.
Take a quiet breath before you begin. Bring before the Lord the things you have waited for, the hopes that feel tired, and the disappointments you rarely speak aloud. Let His Word meet you in the waiting.
“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
Today’s verse reminds us that God’s promise is not a vague comfort, but a word He fulfills in His own time. Sarah did not receive Isaac when believing was easy. She received him when human possibility seemed to have reached its end. May this verse strengthen our hearts as well: God’s timing may not feel fast, but it is never late. His word may require waiting, but it will never fail.
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 the Lord visited Sarah as He had said and fulfilled what He had promised. Now, let us bring our waiting, anxiety, disappointment, and hope before the Lord in prayer.

“Father, thank You for reminding me through the birth of Isaac that You are the God who remembers. You did not forget Sarah, and You did not forget the word You spoke to Abraham. Lord, I confess that when waiting becomes long, I often grow weary, doubtful, and afraid that I have been forgotten by You.
Help me trust Your faithfulness even when I cannot see the outcome. Help me hold on to Your word when my circumstances have not yet changed. When my heart begins to grow discouraged, lift my eyes back to You. Teach me not only to wait for an answer, but to know You more deeply in the waiting. Remind me that Your silence does not mean You are absent, and Your delay does not mean You have failed. Amen.”

“Lord, Genesis 21 tells us that Sarah gave birth at the set time of which You had spoken. You have Your own appointed time, and Your wisdom is greater than my understanding. Yet I often want things to happen according to my schedule, my plan, and my way. When You do not answer according to my expectations, I easily become anxious, disappointed, or restless.
Forgive me for wanting to control what belongs in Your hands. Teach me to surrender my timeline to You again. Help me believe that You know the right time, the right way, and the deeper purpose behind Your work. Keep me from being swallowed by anxiety or disturbed by comparison. Let my heart rest in this truth: what You have spoken, You will fulfill; what You have promised, You will faithfully carry out. Amen.”

“Father, I also pray for the sisters around me who are waiting. Some are waiting for change in their marriage. Some are waiting for their children to grow and return. Some are waiting for physical healing, a job opportunity, a restored relationship, or a new beginning. Some have waited so long that their hearts carry weariness, tears, and disappointments they can hardly express.
Lord, comfort them personally. Let their waiting not lead them into bitterness, but draw them closer to You. Let them not sink into despair, but receive fresh hope from Your presence. Help us also become gentle companions to one another. Keep us from offering shallow words or pressuring others to “just have faith.” Instead, teach us to walk with them through prayer, tenderness, patience, and real love. Amen.”

“Compassionate Father, I also pray for people around the world who are living in long seasons of waiting. Some are waiting for war to end. Some are waiting for justice to be done. Some are waiting to be reunited with family. Some are waiting for food, shelter, healing, and safety. For many, waiting has not lasted a few days, but has stretched into months or years with no clear end in sight.
Lord, have mercy on this broken world. Let Your justice come to the oppressed. Let Your comfort reach the grieving. Let Your provision come to those in need. Let Your peace enter places of violence and fear. Raise up people who are willing to serve as vessels of help, hope, and healing in Your hands. May more people come to know that You are the God who fulfills His word in due time, and the Lord who can turn weeping into joy. Amen.”
As we finish Genesis 21:1–7, we see a child born out of impossibility and a God who never fails His word. Isaac’s birth was not only Sarah’s personal joy; it was a living sign that God keeps His promises. The long years of waiting, the silence after disappointment, and even the laughter that once carried doubt were all transformed by God into laughter that testified to His faithfulness.
As we close this page, we return to real life. Some circumstances may still be unchanged. Some prayers may still feel unanswered. Some waiting may still continue. But remember this: God’s timing is not always the timing we can understand, and His silence is not proof that He has forgotten.
Sarah’s story reminds us that God takes responsibility for what He has spoken, and He fulfills what He has appointed in His time. When something feels too late, too hard, or too impossible, gently tell your heart: “God has not forgotten me. His word will not fail. He can turn tears into laughter.”
May today’s Scripture become strength for your waiting. May you walk through this day with quiet faith, trusting the God who fulfills His word in His appointed time.
