Romans 15:13 May the God of hope fill you with all joy and peace in believing, so that by the power of the Holy Spirit you may abound in hope.
In the 1950s, a Harvard psychologist named Dr. Curt Richter conducted a now-famous experiment involving rats and buckets of water. At first glance, it was a grim study, but a profound truth about the human spirit was buried within it.
In his initial test, Richter placed rats in water to see how long they could swim before giving up. On average, they lasted just 15 minutes before succumbing to exhaustion. But then something remarkable happened, he added the possibility of hope to see the results.
Just before the rats were about to drown, Richter would reach in, pull them out, dry them off, let them rest, and then return them to the water.
And this time?
They didn’t just swim another 15 minutes.
They lasted hours with one rat that continued to swim for an astonishing 60 hours.
What changed? Richter concluded “the rats quickly learn that the situation is not actually hopeless” and that “after elimination of hopelessness the rats do not die.”
Because they had been rescued once, the rats now believed they might be rescued again—and that hope gave them the strength to endure far beyond what they were capable of before.
Let that settle in your heart for a moment: hope kept them swimming.
If hope can keep a tired rat going for 60 hours, imagine what hope in God can do in your life.
Difficult seasons are inevitable. But the crushing weight of hopelessness is far more dangerous than hardship itself.
Hope doesn’t deny the difficulty — it gives us strength in the middle of it. It lifts our eyes off the storm and fixes them on the Savior. And sometimes, that small flicker of hope is all we need to keep swimming.
That’s why Scripture reminds us that the God of hope is able to fill us with joy and peace as we trust in Him—so that, by the power of the Holy Spirit, we can overflow with hope even in the hardest moments.
Perhaps you feel like you’re treading water, moments from going under. Maybe someone close to you is silently struggling to stay afloat. Never underestimate the power of hope, especially the kind rooted in Yeshua (Jesus). It can carry you further than you ever imagined.

Jonah now acknowledges that God put him where he is, and he accepts His discipline. “Sheol” is the “grave”, the “pit” or the “abode of the dead”. Did Jonah die, or was he only nearly dead from three days of fish stomach acid, and little or no air? The text doesn’t say; only that if he didn’t actually leave his body, he came as close as a man can get to it; three days worth. In this nebulous and miserable place Jonah cried out, probably from the deepest depths of his agonized soul…he cried out to the Lord.
While most read the story of Jonah focusing on Jonah’s journey, I want to pause and examine the lives of the pagan sailors. What a journey they were on! We see the hand of God touching them providentially through Jonah’s disobedience. Talk about God bringing good from evil.
So the captain came to Jonah, and said to him, “What do you mean, sleeper? Arise, call on your God; perhaps your God will consider us, so that we may not perish.” At this point the captain (who probably worshiped Baal and Yamm, god of the sea) has more faith than Jonah.
It must have been a bad storm. These men were experienced, hardened sailors who had seen it all at sea. If they were scared, this could have been the first “perfect storm” since Noah’s flood. So they started the first interfaith prayer meeting in the Bible, each man crying out to his own god. As the ship groaned and creaked in howling wind and massive waves, and the men threw cargo overboard in a desperate attempt to save it, where was Jonah? On deck helping them? Confidently praying to His own God? Shaking with fear and paralyzed with deep conviction? No, he’s taking a nap down below…
Back in the third century Cyprian the Bishop of Carthage wrote to his friend Donatus: “It is a bad world, Donatus, an incredibly bad world. But I have discovered, in the midst of it, a quiet and holy people who have learned a great secret.
For the next week or so we’ll be looking closely at the life of Jonah the prophet. Jonah was told to “preach against the city of Nineveh”, that was in the ancient kingdom of Assyria. Nineveh was a major city on the banks of the Tigris River about 500 miles north and east of where Jonah was; located on a contemporary map in modern Iraq, about 300 miles north of Baghdad. Archaeologists have found the ruins of ancient Nineveh right outside the Iraqi city of Mosul. Yes, the same Mosul that was taken last week by jihadists!
So Jonah goes and begins to preach in this pagan city. His message is very simple. “Forty more days and Nineveh will be overthrown”(v. 4). That’s it. That was his whole message. It’s eight words in English; only 4 words in Hebrew.
