One-Year Bible Reading Plan  : Seekers & New Believers |  September 30 | Genesis Chapter 21: The Birth of Isaac, Hagar in the Wilderness, and the Everlasting God at Beersheba 

🦌 Opening Today’s Reading 

Dear brothers, sisters, and friends, peace be with you in the Lord!

Welcome to Day 13 of our Old Testament journey! Today, we explore Genesis Chapter 21.

After 25 long years of waiting since God's first call in Genesis 12, the long-awaited dawn arrives in Chapter 21: "And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken." One-hundred-year-old Abraham and ninety-year-old Sarah embrace Isaac, the son of promise, whose name means "Laughter."

Yet alongside this holy joy, Chapter 21 records a painful departure—Hagar and Ishmael are sent into the wilderness of Beersheba, where God dramatically intervenes to save them. The chapter closes with Abraham making a covenant with Abimelech and planting a tamarisk tree, calling upon Jehovah as El Olam—the Everlasting God.

Let us step into today's passage with joyful gratitude and reverence.

📖 Context Snapshot 

Previously in Genesis: Judgment on Sodom & Preserved in Gerar (Ch. 19–20)

Chapter 19 detailed God's judgment upon Sodom and Gomorrah, while Lot escaped. Chapter 20 recounted Abraham's journey to Gerar and his compromise regarding Sarah; God intervened in a dream to King Abimelech, protecting Sarah and restoring Abimelech's household.

Chapter 21 brings the appointed time of God's promise to pass.

Today's Story: Isaac's Birth, Hagar's Rescue, and the Well of Beersheba

1. The Birth & Circumcision of Isaac (v. 1–7): The Lord visited Sarah at the set time whereof God had spoken to him. Abraham named his son Isaac ("Laughter") and circumcised him on the eighth day as God commanded. At 100 years old, Abraham celebrated with Sarah, who proclaimed: "God hath made me to laugh, so that all that hear will laugh with me."

2. The Weaning Feast & Departure of Hagar (v. 8–14): At Isaac's weaning feast, Sarah saw Ishmael (son of Hagar) mocking. Sarah demanded: "Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac." Though Abraham was grieved, God instructed him to listen to Sarah, for "in Isaac shall thy seed be called," while also promising to make Ishmael a nation. Abraham rose early, gave provisions and a bottle of water to Hagar, and sent them away.

3. God Hears in the Wilderness (v. 15–21): Wandering in the wilderness of Beersheba, the water was spent. Hagar placed the child under a bush and sat a bowshot away, weeping. God heard the voice of the lad, and the Angel of God called to Hagar: "Fear not; for God hath heard the voice of the lad where he is." God opened her eyes to see a well of water. God was with the lad as he grew up in the wilderness of Paran as an archer.

4. Covenant at Beersheba & El Olam (v. 22–34): Abimelech and Phichol acknowledged God's presence with Abraham and sought a treaty of peace. After resolving a dispute over a well of water, Abraham set aside seven ewe lambs as a witness that he had dug the well, naming the place Beersheba ("Well of the Oath"). Abraham planted a grove (tamarisk tree) in Beersheba and called there on the name of the LORD, the Everlasting God (El Olam).

💡 Questions to keep in mind while reading today:

1. On God's Timetable: After 25 years, God fulfilled His promise precisely as He had spoken. How does this encourage your patience in waiting on God's answers?

2. On the Flesh vs. the Promise: Galatians 4 interprets Ishmael as born of the flesh and Isaac born of the Spirit/promise. What habits or self-reliant schemes might God be calling you to cast out today?

3. On "The Everlasting God" (El Olam): Abraham planted a slow-growing tamarisk tree and worshiped El Olam. How does anchoring in an eternal God give you peace over your present and future?

💡 Today’s Scripture Verse - Genesis 21

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.

8 And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned.

9 And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.

10 Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.

11 And the thing was very grievous in Abraham's sight because of his son.

12 And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called.

13 And also of the son of the bondwoman will I make a nation, because he is thy seed.

14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.

15 And the water was spent in the bottle, and she cast the child under one of the shrubs.

16 And she went, and sat her down over against him a good way off, as it were a bow shot: for she said, Let me not see the death of the child. And she sat over against him, and lift up her voice, and wept.

17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.

18 Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.

19 And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink.

20 And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer.

21 And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt.

22 And it came to pass at that time, that Abimelech and Phichol the chief captain of his host spake unto Abraham, saying, God is with thee in all that thou doest:

23 Now therefore swear unto me here by God that thou wilt not deal falsely with me, nor with my son, nor with my son's son: but according to the kindness that I have done unto thee, thou shalt do unto me, and to the land wherein thou hast sojourned.

24 And Abraham said, I will swear.

25 And Abraham reproved Abimelech because of a well of water, which Abimelech's servants had violently taken away.

26 And Abimelech said, I wot not who hath done this thing; neither didst thou tell me, neither yet heard I of it, but to day.

27 And Abraham took sheep and oxen, and gave them unto Abimelech; and both of them made a covenant.

28 And Abraham set seven ewe lambs of the flock by themselves.

29 And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?

30 And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.

31 Wherefore he called that place Beersheba; because there they sware both of them.

32 Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines.

33 And Abraham planted a grove in Beersheba, and called there on the name of the Lord, the everlasting God.

34 And Abraham sojourned in the Philistines' land many days.

🌟Daily Heart-Check: From "Promised Laughter" to "The Everlasting Oasis" 

Synchronized with the core questions from our reading guide:

• God's Promises Are Guaranteed by His Character:
  Genesis 21:1 emphasizes God's absolute truthfulness: "as He had said... as He had spoken." The 25-year delay was not divine neglect, but divine preparation. When God's appointed hour strikes, sorrow yields to holy laughter. No word from God will ever fail.

• Separating Self-Reliance from Divine Promise:
  Ishmael represented the product of human effort and compromise, while Isaac represented God's miraculous gift. In our spiritual walk, God calls us to relinquish fleshly striving and control, allowing the life of Christ's promise to take total precedence in our hearts.

• El Olam — The God Who Sees, Hears, and Endures Forever:
  In the dry sands of Beersheba, God heard the crying child and opened Hagar's eyes to a hidden well. Later, Abraham planted a shade tree and worshiped El Olam (The Everlasting God). A tamarisk tree grows slowly, offering shade for generations to come. Abraham had learned to rest in a God who transcends human time and keeps His covenant forever.
