The answer is: Obadiah

Only containing one chapter, and notoriously difficult to find in a hurry!

Obadiah may be tiny, but it packs a powerful punch! When you flip to this shortest book in the Old Testament, Don’t be surprised if you miss it because it’s tucked neatly between Amos and Jonah. A one-chapter biblical gem, it's often overlooked: preachers might skip straight from the lengthy books to the more popular stories. Yet Obadiah has a fantastic backdrop — it’s a prophetic vision about the downfall of Edom and exploration of themes like pride and justice.

Interestingly, this 21-verse work delves deep into the relationship between Israel and Edom. Edomites were descendants of Esau, Jacob's brother, so there's a classic sibling tension. The book reminds readers of biblical karma: history can swing back around! Plus, there’s an echo of something insightful—many scholars note how other prophetic books like Isaiah also highlight judgments against nations, weaving a narrative of divine justice throughout the scriptures.

Did you know that since Obadiah is so short, you can often read through it in the time it takes to sip your coffee? Not only does it clarify the destiny of nations, but it also encourages self-reflection on how actions have consequences. So, the next time you come across Obadiah, remember that sometimes the smallest voices carry profound lessons!
