What does the Bible say about the transience of earthly power?

Scripture repeatedly emphasizes the transient nature of earthly power and success. For example, Psalm 39:5 states, 'Surely every man walks about like a shadow; surely they busy themselves in vain; he heaps up riches, and does not know who will gather them.' This reflects the idea that worldly achievements and stature do not endure. The account of the Duke of Sully illustrates this truth; despite his wealth and influence, he faced great personal struggles and ultimately met a sad end, affirming that worldly laurels are ephemeral. Thus, the Christian is reminded to seek treasures that are eternal, rather than those that are temporary and corruptible, as seen in Matthew 6:19-21.
