Download Lesson NoteTopic: God’s Promises And Fulfilment. The Birth Of Isaac

Behavioural Objectives:
By the end of the lesson, pupils should be able to:
- State the name of the man God made a special promise to.
- Narrate the story of the birth of Isaac as a fulfillment of God’s promise.
- List at least three promises God made to Abraham.
- Explain why it is important to trust God’s promises using biblical and classroom examples.
Instructional Materials:
- Bible (Genesis 17:1–22; Genesis 21:1–7)
- Chart showing Abraham’s family tree
- Visual aid: Picture of a baby (Isaac)
- Drawing of stars and sand (to illustrate God’s promise)
- Flashcards with keywords: Promise, Faith, Fulfillment, Obedience
Entry Behaviour:
Pupils have previously learned about God’s faithfulness and basic Bible stories.
Set Induction (Introduction):
Teacher shares this short story to build interest:
“Imagine someone promises you a beautiful gift on your birthday, but it doesn’t come immediately. You wait and wait – maybe for days or months. But one day, when you least expect it, the gift arrives! That’s how God’s promise to Abraham was fulfilled – it took time, but God kept His word.”
Lesson Development:
Step 1: Who Was Abraham?
About Abraham:
- Abraham was a faithful servant of God
- God chose him to be the father of many nations
- God made a covenant (a strong promise) with Abraham
Classroom Example: Teacher shows a poster of Abraham’s family and says, “Just like your father takes care of you, God took care of Abraham’s family too.”
Step 2: The Promises God Made to Abraham
God made several promises to Abraham:
- He would be the father of many nations.
- His descendants would be as many as the stars in the sky and the sand on the seashore.
- He would have a son even though he and his wife Sarah were old.
- God would give his family a promised land (Canaan).
- Through him, all nations would be blessed.
Bible Reading: Genesis 17:1–8
Step 3: The Birth of Isaac – God Fulfills His Promise
The Fulfillment:
- Abraham was 100 years old when Isaac was born.
- Sarah, his wife, had laughed when God first made the promise because she thought it was impossible.
- But in Genesis 21:1–7, we see that God kept His promise – Isaac was born!
Classroom Discussion Question: “Why do you think Sarah laughed when she heard the promise?” (Expected response: She was old and didn’t believe it at first.)
Step 4: Lessons from the Story
Key Lessons:
- God always keeps His promises – even if it takes time.
