El Olam: The God Who Never Changes

God reveals Himself in Genesis 21 as El Olam, the eternal God who never changes. The text begins with God doing exactly what He said He would do. Sarah bears Isaac at the very time God promised, and the laughter that once sounded impossible becomes a house full of joy. Abraham tried to get ahead of God at eighty-six, but at one hundred he is changing diapers because nothing is too hard for God. God is never late. He is always on time, even when His timetable does not look anything like man’s.

God’s plans also prove better than anything Abraham and Sarah could have drawn up. Isaac means laughter, because God took what looked like a joke and turned it into a miracle. God does not need man’s help to make His promises happen. He calls for obedience, then He works in such a way that He gets all the credit and all the glory.

God’s standards never change either. Ishmael represents Abraham’s attempt to bypass God’s plan, and his continued stirring up of strife cannot remain in the household of promise. Abraham loves Ishmael, so sending him away hurts deeply. Yet God shows that there are Ishmaels in life that must go if God’s people are going to be and do all He has called them to be. Familiar habits, media, relationships, addictions, and compromises may feel dear, but nobody can stay where they are and go forward with God.

God’s grace never changes. Hagar is separated, destitute, helpless, and hopeless in the wilderness. Yet God sees her pain, hears the boy crying, and opens her eyes to water that had been there all along. The well becomes a picture of Jesus, the living water for thirsty souls. Salvation is available, but it must be received. God opens blind eyes, but each person must turn from sin and self and come to Christ.

Abraham’s tamarisk tree becomes a living reminder that circumstances change, but God does not. The cross gives the greatest declaration of El Olam. God’s promises never fail, His holy standard is never lowered, and His grace never runs out. Jesus bears sin because man could never meet God’s standard, and God’s love is put on full display because Christ pays what sinners could not pay.

Key Takeaways

• 1. God is always right on time God’s timing can feel late when the waiting gets long and the situation looks dead. Isaac’s birth and Lazarus’s resurrection both show that God is never scrambling to catch up. God works on an appointed timetable, and His delay never means His absence. [48:23]
• 2. Some Ishmaels have to go Ishmaels are the things born from impatience, compromise, or trying to make life work apart from God’s way. They can be deeply familiar and painful to release, which is why Abraham was distressed. Yet God’s call to move forward often requires sending away whatever keeps a life divided. [53:30]
• 3. God opens eyes to living water Hagar could not see the well even though it was near her in the wilderness. Spiritual thirst can leave people searching through money, pleasure, substances, and relationships while Christ stands as the only water that satisfies. God graciously opens eyes, but each person must come and drink. [58:03]
• 4. God’s holiness and grace meet at Calvary The cross proves that God did not lower His standard to excuse sin. Sin had to be paid for, and Jesus became sin so that sinners could stand before God dressed in His righteousness. The cross shows both the seriousness of sin and the depth of God’s love. [1:05:30]

Bible Reading

Genesis 21:1-33
“The LORD visited Sarah as he had said, and the LORD did to Sarah as he had promised. And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him. Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac. And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. Abraham was a hundred years old when his son Isaac was born to him. And Sarah said, 'God has made laughter for me; everyone who hears will laugh over me.' And she said, 'Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.' And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned. But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing. So she said to Abraham, 'Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.' And the thing was very displeasing to Abraham on account of his son. But God said to Abraham, 'Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. And I will make a nation of the son of the slave woman also, because he is your offspring.' So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba. When the water in the skin was gone, she put the child under one of the bushes. Then she went and sat down opposite him a good way off, about the distance of a bowshot, for she said, 'Let me not look on the death of the child.' And as she sat opposite him, she lifted up her voice and wept. And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, 'What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.' Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow. He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt. At that time Abimelech and Phicol the commander of his army said to Abraham, 'God is with you in all that you do.' Abraham planted a tamarisk tree in Beersheba and called there on the name of the LORD, the Everlasting God.” [38:24]

John 4:13-14
“Jesus said to her, 'Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” [58:03]

John 7:37
“On the last day of the feast, the great day, Jesus stood up and cried out, 'If anyone thirsts, let him come to me and drink.” [58:03]

Observation questions

1. What repeated phrases in Genesis 21:1–7 emphasize that Sarah’s pregnancy and Isaac’s birth happened exactly as God had promised? [47:01]
2. What details show both the joy surrounding Isaac’s birth and the surprising nature of God’s provision for Abraham and Sarah?
3. What happens between Ishmael and Isaac’s family at the feast, and how does Abraham respond when Sarah asks for Hagar and Ishmael to leave? [52:09]
4. What does God do for Hagar and Ishmael after their water is gone in the wilderness, and what does Hagar have to do after God opens her eyes? [57:44]

Interpretation questions

1. Why does the passage make such a point that Isaac arrived at the exact time God promised? What does this show about God’s timing when His people have waited a long time? [48:07]
2. Ishmael was deeply loved by Abraham, yet his presence was bringing strife into the household of promise. How does this help explain why releasing a sinful or unhealthy attachment can be painful but necessary? [53:02]
3. Hagar could not see the well until God opened her eyes. In what ways do John 4:13–14 and John 7:37 explain the well as a picture of the spiritual life Jesus gives? [58:41]
4. How does the cross show both that God does not lower His standard for sin and that His grace is fully available to sinners? [01:05:17]

Application questions

1. Where is the waiting especially difficult right now—perhaps in a family situation, health concern, unanswered prayer, or major decision? What would it look like to trust that God is not late, even without knowing His timetable? [48:23]
2. Has there been a time when trying to force a solution, control an outcome, or get ahead of God created more trouble? What might patient obedience look like in that area now? [50:01]
3. An “Ishmael” can be a familiar habit, form of media, relationship, addiction, or compromise that keeps a person from moving forward with God. Is there anything in life that has become too dear to release even though it is pulling the heart away from God? What wise, concrete step could help address it? [01:09:24]
4. Hagar’s well was already there, but she needed God to open her eyes. Where might someone be looking for satisfaction in things that cannot truly satisfy—such as money, achievement, pleasure, substances, or relationships? How can the group encourage one another to keep coming to Jesus, the living water? [58:03]
5. Abraham planted a tamarisk tree as a reminder that God is eternal and unchanging. What regular reminder—a Scripture, prayer practice, note, conversation, or visible object—could help keep God’s faithfulness in view when circumstances shift? [01:02:48]
6. Would people who know the group members well see evidence that God is at work in their homes, relationships, priorities, and responses to hardship? What is one area where a clearer witness to God’s presence could grow this week? [01:01:29]
