Moses and Israel Sing to the Lord — Exodus 15:1–3

After witnessing the miraculous crossing of the Red Sea and the destruction of Pharaoh’s army, Moses and the Israelites responded with worship. They did not remain silent after experiencing God’s deliverance. They turned their experience into a song of praise.

Moses led the people in celebrating the Lord’s victory:

“The LORD is my strength and my song, and He has become my salvation.”

The Israelites recognized that their victory did not come from their own strength. They had been trapped between Pharaoh’s army and the sea, but God Himself had made a way for them.

Their song became a testimony of what God had done.

• God had delivered them from slavery.
• God had protected them from Pharaoh’s army.
• God had opened the Red Sea.
• God had brought them safely to the other side.
• God had defeated the enemy they could never have defeated themselves.

Their worship reminded them that the Lord was not merely a God they had heard about. He was their Deliverer.

Pharaoh’s Army Is Defeated — Exodus 15:4–12

The song then remembers what happened to Pharaoh and his army.

The Israelites praise God because Pharaoh’s chariots and soldiers were thrown into the sea. The powerful Egyptian army that had terrified them only moments earlier had disappeared beneath the waters.

The song describes the Egyptian soldiers sinking like stones into the depths.

The people understood that this was not an ordinary military victory. Israel had no army capable of defeating Egypt. God had fought on their behalf.

They declare:

“Your right hand, O LORD, glorious in power…”

God’s power had shattered the enemy.

This is an important part of their worship. They were not simply celebrating that a difficult situation had ended. They were celebrating who God is.

“Who Is Like You, O Lord?” — Exodus 15:11–13

The song reaches a beautiful declaration:

“Who is like you, O LORD, among the gods?”

The Israelites had seen the greatness of God with their own eyes. Egypt had many gods, but none of them could rescue Pharaoh or stop the God of Israel.

The Lord was:

• Majestic in holiness
• Awesome in glorious deeds
• Powerful in wonders
• Faithful in His love
• Mighty to save

The Israelites recognized that God had not simply rescued them and abandoned them. His purpose was to lead them forward.

The song says that God had led His redeemed people in His steadfast love.

God Will Bring His People Home — Exodus 15:13–18

The song looks beyond the Red Sea toward the future.

The Israelites had only just escaped Egypt, yet they were already singing about God bringing them into the land He had promised.

They believed that the God who had begun their deliverance would also complete it.

The song speaks of God bringing His people to His mountain and establishing them in the place He had prepared.

Then comes a powerful declaration:

“The LORD will reign forever and ever.”

This is the ultimate truth behind their celebration. Pharaoh’s kingdom had fallen, but God’s reign would never end.

Human rulers rise and fall. Powerful nations come and disappear. But the Lord remains King forever.

Miriam Leads the Women in Worship — Exodus 15:19–21

Miriam, the sister of Moses and Aaron, also led the women of Israel in worship.

She took a tambourine, and the women followed her with tambourines and dancing.

Miriam sang:

“Sing to the LORD, for He has triumphed gloriously.”

The entire community joined in celebrating God’s salvation.

Their worship involved singing, music, movement, and joyful remembrance. They were making sure that this great act of God would remain part of their collective memory.

From Celebration to Testing — Exodus 15:22–24

After such a powerful experience, the Israelites began their journey into the wilderness of Shur.

They had just seen the Red Sea divided.

They had just watched Pharaoh’s army disappear.

They had just sung a powerful song declaring God’s greatness.

But only three days later, they faced another problem.

There was no water.

For three days they travelled without finding anything to drink. Eventually, they came to a place called Marah.

They finally found water—but it was bitter and could not be consumed.

The people immediately became upset and began grumbling against Moses:

“What shall we drink?”

This moment reveals how quickly fear and frustration can replace faith.

God Makes the Bitter Water Sweet — Exodus 15:25–26

Moses cried out to the Lord.

Instead of abandoning His people, God showed Moses what to do. He directed him to a piece of wood, which Moses threw into the water.

The bitter water became drinkable.

Once again, God demonstrated His ability to provide for His people in a situation they could not solve themselves.

Marah became another lesson in trusting God.

God then gave Israel instructions concerning obedience. He called them to listen carefully to His voice, do what was right, and follow His commands.

He reminded them that He was the Lord who heals and protects His people.

The wilderness was going to teach Israel something they had not yet fully learned in Egypt: freedom requires trust and obedience.

From Marah to Elim — Exodus 15:27

After Marah, God led the Israelites to Elim.

What a contrast!

At Marah, there was water, but it was bitter.

At Elim, there were twelve springs of water and seventy palm trees.

God had not forgotten His people.

The difficult place was not their final destination.

Marah was part of the journey, but it was not the end of the journey.

Do Not Forget the Red Sea

One of the strongest lessons from Exodus 15 is how quickly people can forget God’s faithfulness.

Three days earlier, Israel had witnessed one of the greatest miracles recorded in Scripture.

They had stood before the Red Sea with no visible escape.

God opened the sea.

They walked through on dry ground.

Pharaoh’s army was destroyed.

They sang about God’s power.

Yet three days later, when they encountered bitter water, they were already complaining.

This is something we can easily recognize in ourselves.

When God solves one problem, we feel relieved and grateful. But when another problem appears, we may immediately become anxious again.

We remember the current difficulty more clearly than the previous miracle.

Remember God’s Faithfulness — Application

The Israelites teach us the importance of remembering.

When a new difficulty comes, we should not allow the new problem to erase the memory of God’s previous faithfulness.

If God helped us before, His character has not changed.

If He provided before, He is still able to provide.

If He opened a way before, He can open another way.

When we feel ourselves becoming discouraged, we can deliberately remind ourselves:

• “God has helped me before.”
• “God has carried me through difficult seasons.”
• “God has answered prayers before.”
• “God has provided when I did not know how things would work out.”
• “This problem is new, but God is not new.”
• “The God who was faithful yesterday is still faithful today.”

Preach God’s Faithfulness to Yourself

Sometimes faith means reminding ourselves of what we already know.

When fear says, “There is no way,” remember the Red Sea.

When anxiety says, “God has forgotten you,” remember His past faithfulness.

When a new Marah appears in life, remember that God has already brought you through other difficult places.

Israel’s mistake was not that they had a problem. Their mistake was allowing the problem to make them forget the God who had already delivered them.

We will all encounter our own “Marah” moments—situations that feel bitter, disappointing, confusing, or impossible.

But Marah does not mean God has abandoned us.

Sometimes the next Elim is closer than we realize.

Final Application

Exodus 15 begins with a song of victory and quickly moves into a test of faith.

That is often how life works.

We can experience God’s goodness one day and face a completely different struggle the next. The presence of a new difficulty does not cancel the faithfulness of God.

So, when the waters become bitter, remember the Red Sea.

Remember what God has already done.

Remember His kindness.

Remember His promises.

And instead of becoming a complainer at every new difficulty, learn to preach God’s past faithfulness to your own heart.

The God who brought Israel through the sea was still with them at Marah—and the God who was faithful yesterday is still faithful today.
