When God Tests What We Trust

Exodus 15:22–27
“So he cried out to the Lord, and the Lord showed him a tree. When he cast it into the waters, the waters were made sweet. There He made a statute and an ordinance for them, and there He tested them,”
‭‭Exodus‬ ‭15‬:‭25‬ ‭NKJV‬‬


Tests from God are designed not to destroy our faith, but to disclose it.”

— Warren Wiersbe

In 1853, before leaving England as a young missionary to China, Hudson Taylor was working as a medical assistant in London. His employer—a busy doctor—often forgot to pay him on time. Taylor was broke, with no money even for food, yet he felt God impressing on him a lesson: “Don’t ask for the money. Pray instead. Let this be your test.”

For days, Taylor prayed silently as hunger grew.

One night, the doctor reached into his pocket and said, “Oh, I meant to pay you—but I have no change. I’ll give it tomorrow.”Hudson Taylor walked home cold, hungry, and discouraged. He wrote later, “That night, God tested my faith almost to breaking.”

Israel has just marched out of the Red Sea triumphantly. Only days before, they saw God split the waters, silence the Egyptian army, and lead them out with a mighty hand. Their hearts were singing; their faith felt strong.

But only three days into the wilderness, everything changes.The sun scorches. The water supply dries up. Hope fades. When they finally reach Marah and find water, the relief turns into frustration—because the water is too bitter to drink. The same people who sang praises now raise complaints.

In that moment, God introduces something they hadn’t faced yet: a test.

Not a test of survival—God already proved He could provide.

Not a test of His power—He already displayed it in Egypt.

This was a test of their heart.

Would they trust Him when the conditions changed?

Would they obey even when the answer was not immediate?

Would they still believe when their expectations collided with reality?

God turns the bitter water sweet, but before doing that, He reveals what was bitter inside them.At Marah, He wasn’t just testing the water—He was testing His people.

The Hebrew word for tested in Exodus 15:25 is נָסָה (nāsâ)—a word that means to test, try, prove, or expose. God was not punishing Israel; He was trying them.Israel needed to learn whether they were people who worshipped occasionally but murmured normally—or people who trusted even when the road grew dry. They had seen miracles, but miracles do not automatically produce maturity. Only testing does that.
Tests reveal:
• What we rely on.
• What we fear.
• What we truly believe when no song is left on our lips.
• Whether our obedience is rooted in convenience or conviction.

God’s tests are not random hardships. They are purposeful opportunities where God shows us what is inside us—and shapes us into who He wants us to become.

At Marah, the question was not, “Can God make bitter water sweet?”
It was, “Can Israel trust God when life tastes bitter?”

End of the story : 

The next morning, unexpectedly, someone knocked at his employer’s door.

A patient had come early—to pay a bill in cash. The doctor immediately handed the full amount to Hudson Taylor, without Taylor ever mentioning his need.

Hudson Taylor wrote:“God was testing whether I trusted Him or human channels. When the test was complete, the provision arrived.”

This became one of the foundational lessons of his life and ministry.For the next 50 years, Taylor depended on God alone to support thousands of missionaries in the China Inland Mission—because God had first tested his trust in that small London room.

Just like Israel at Marah, the test came before the provision.His story mirrors Marah: God tests us to reveal what we trust when nothing seems to be enough.

There are moments when we too arrive at our own “Marah”—bitter situations, disappointing turns, unanswered needs, or delays we did not expect. During these moments, God is not being silent; He is testing us.

He tests our obedience when instructions feel inconvenient.

He tests our faith when the answer is not instant.

He tests our patience when the journey feels long.

He tests our heart when disappointment comes before provision.

These tests do not show God who we are—He already knows.

They show us who we are, so we can grow into who He desires us to be.

Instead of murmuring, we learn to worship.

Instead of doubting, we learn to trust.

Instead of reacting, we learn to obey.

Every test is God shaping our faith, not shattering it.

🙏  Prayer:

Lord, teach us to trust You in every test.When life feels bitter, help us obey Your voice, lean on Your Word, and walk in faith rather than complaint. Shape our hearts through every trial, and make us a people who trust You deeply. Amen.
