Theme

Understanding God’s covenant relationship through Noah, Abraham, and David

Lesson Objective

By the end of this lesson, participants should understand what a biblical covenant is, recognize the promises God made to Noah, Abraham, and David, and see how these covenants reveal God’s faithfulness and ultimately point toward Jesus Christ.

Introduction: What Is a Covenant?

We live in a world of agreements.

We sign contracts for houses. We enter agreements for cars. We accept terms for employment. We even click “I agree” on our phones without reading what we just agreed to!

But when we come to Scripture, we encounter something deeper than a contract. We encounter a covenant.

A contract is primarily an agreement based upon conditions and obligations.

A biblical covenant is a solemn, binding relationship established by God involving promises, commitments, and often a sign.

Throughout Scripture, God repeatedly reveals Himself as a covenant-making and covenant-keeping God.

And that’s important because the Bible is not simply a collection of disconnected stories. Noah, Abraham, David, the prophets, the birth of Jesus, Calvary, and the resurrection are connected pieces of God’s redemptive plan.

Today we’re going to examine three major covenants:

Noah — A Covenant of Preservation
Abraham — A Covenant of Promise
David — A Covenant of a King

And when we put all three together, we discover that God always keeps His word.

Point 1: NOAH — GOD’S COVENANT OF PRESERVATION

Scripture: Genesis 9:8–13

After the flood, Noah stepped out of the ark into a completely different world.

God had judged human wickedness through the flood, but afterward God established a covenant with Noah, his descendants, and every living creature.

Genesis 9:11 declares:

“Neither shall all flesh be cut off any more by the waters of a flood…”

God promised that He would never again destroy the earth with a flood.

The Covenant Was Initiated by God

Notice that Noah didn’t approach God with a proposal.

God approached Noah.

God said:

“I establish my covenant with you…”

This teaches us something fundamental about biblical covenants: God takes the initiative.

Grace begins with God.

God reaches toward humanity before humanity can ever reach toward Him.

The Covenant Extended Beyond Noah

God’s promise wasn’t limited to one man.

It extended to:

Noah

Noah’s descendants

Every living creature

Future generations

God was establishing stability in the created order so His redemptive plan could continue.

The Sign Was the Rainbow

Genesis 9:13

“I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.”

The rainbow became a visible reminder of God’s promise.

Every time the storm came and the rainbow appeared, it testified:

God remembers His covenant.

That’s a powerful picture.

The rainbow doesn’t mean storms will never come again.

It means the storm does not cancel the promise.

You can experience rain and still have a promise.

You can experience storms and still have a covenant.

You can experience difficult seasons and still know:

God has not forgotten what He said.

Discussion Question

Why do you think God gave Noah a visible sign of His covenant? How can remembering God’s promises strengthen us during difficult seasons?

Point 2: ABRAHAM — GOD’S COVENANT OF PROMISE

Scripture: Genesis 12:1–3

Years later, God called a man named Abram.

God told him:

“Get thee out of thy country…”

Abraham didn’t know every detail of where he was going.

He simply had a word from God.

And with that command came an extraordinary promise.

God promised Abraham:

Land.

Descendants.

Blessing.

And ultimately:

“In thee shall all families of the earth be blessed.”

This covenant wasn’t only about Abraham becoming prosperous.

God was beginning something through Abraham that would eventually bless the entire world.

The Promise Required Faith

There was one major problem.

God promised Abraham descendants, but Abraham and Sarah had no children.

As time passed, God’s promise appeared increasingly impossible.

Yet Genesis 15:5 says God brought Abraham outside and told him:

“Look now toward heaven, and tell the stars…”

Then God said:

“So shall thy seed be.”

Abraham couldn’t see the fulfillment yet.

But God allowed him to see a picture of the promise.

Genesis 15:6 says:

“And he believed in the LORD; and he counted it to him for righteousness.”

That’s faith.

Faith says:

“I don’t know how God is going to do it, but I believe God is going to do what He said.”

The Covenant Was Bigger Than Abraham

God later changed Abram’s name to Abraham.

Abram meant exalted father.

Abraham meant father of many nations.

Every time someone called his new name, they were speaking God’s promise over his life.

But the greatest fulfillment went beyond Isaac.

Matthew begins the genealogy of Jesus by identifying Him as:

“The son of David, the son of Abraham.”

Through Abraham’s family line eventually came Jesus Christ.

Paul explains in Galatians 3 that God’s promise to Abraham ultimately finds its fulfillment in Christ.

So when God told Abraham:

“All nations will be blessed through you,”

God was already pointing toward Jesus.

Discussion Question

Abraham had to trust God’s promise before he could see its fulfillment. What makes waiting on God’s promises difficult, and what can Abraham teach us about trusting God while we wait?

Point 3: DAVID — GOD’S COVENANT OF A KING

Scripture: 2 Samuel 7:12–16

Now the covenant story moves from Noah…

to Abraham…

to David.

David wanted to build God a house.

But God essentially told David:

“You’re talking about building Me a house, but I’m going to build you a house.”

Not merely a physical house.

A dynasty.

God promised David:

“And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.”

That’s an enormous promise.

David’s descendants would rule after him.

His son Solomon would sit upon the throne.

But God’s promise stretched beyond Solomon.

Because earthly kings eventually died.

Kingdoms eventually fell.

Jerusalem was eventually conquered.

So how could David’s throne be established forever?

The answer comes in Jesus.

Jesus Is the Promised King

When the angel Gabriel announced Jesus’ birth to Mary, he said:

Luke 1:32–33

“The Lord God shall give unto him the throne of his father David…”

And:

“Of his kingdom there shall be no end.”

There’s the Davidic covenant.

God didn’t forget David.

Hundreds of years had passed.

Generations had come and gone.

Circumstances had changed.

But God’s covenant remained.

Jesus Christ came as the promised Son of David and everlasting King.

Discussion Question

What does God’s faithfulness to David across many generations teach us about God’s timing compared with our timing?

PUTTING THE THREE COVENANTS TOGETHER

Now look at the progression.

Noah — God Preserves

God preserves the world so His redemptive purpose can continue.

The sign: the rainbow.

Abraham — God Promises

God chooses a family through whom all nations will ultimately be blessed.

The sign: circumcision.

David — God Establishes a King

God promises a kingdom and throne that will ultimately endure forever.

The fulfillment: Jesus Christ, the Son of David.

Do you see the movement?

Noah — preservation.

Abraham — promise.

David — kingdom.

And they are all moving toward Christ.

THE NEW COVENANT — JESUS

Scripture: Luke 22:20

At the Last Supper, Jesus took the cup and said:

“This cup is the new testament in my blood, which is shed for you.”

The word translated testament is also the word associated with covenant.

Jesus was announcing:

A new covenant is being established through My blood.

God’s redemptive plan wasn’t abandoned.

It was reaching its climax.

The covenant promises running through Scripture ultimately lead us to Calvary.

At the cross, Jesus shed His blood for our sins.

He died.

He was buried.

And on the third day…

He got up from the grave.

And because He lives, everyone who places faith in Christ can receive forgiveness, reconciliation with God, and eternal life.

Three Truths to Remember

God Initiates the Covenant

Noah didn’t invent the covenant.

Abraham didn’t invent the covenant.

David didn’t invent the covenant.

God did.

God has always been reaching toward humanity.

God Remembers His Covenant

Generations may change.

Circumstances may change.

People may change.

But God’s character doesn’t change.

If God said it, He remains faithful to His word.

God’s Covenants Point Toward Christ

The covenant story isn’t simply about Noah’s rainbow, Abraham’s descendants, or David’s throne.

It ultimately leads us to Jesus.

Jesus is connected to Abraham’s promised blessing.

Jesus is David’s promised King.

And through Jesus we enter the blessings of the New Covenant.

Final Discussion

Looking at Noah, Abraham, and David together, what do these three covenants teach us about the character of God?

How does understanding these covenants change the way you read the Old Testament and understand Jesus?

Which aspect of God’s covenant faithfulness—preservation, promise, or kingship—speaks most strongly to where you are in your walk with God today, and why?

Closing Thought: God Keeps His Word

Church, that’s the thread running through every covenant:

God keeps His word.

When Noah saw the rainbow — God kept His word.

When Sarah gave birth to Isaac — God kept His word.

When David received the promise of an everlasting throne — God kept His word.

And when Jesus was born in Bethlehem…

When He walked toward Calvary…

When He died on the cross…

When they placed Him in the tomb…

And when Sunday morning came and He rose with all power in His hands…

God was still keeping His word.

So when you read about the covenants, don’t just study what God promised them.

Learn something about the God who made the promise.

Because the God of Noah, Abraham, and David is still a faithful, covenant-keeping God.
