What does Isaiah 46 say about God's control over the nations?

In Isaiah 46, God reveals His absolute sovereignty over the nations and history. He declares, 'I have spoken it, I will also bring it to pass; I have purposed it, I will also do it.' This reflects His authority to orchestrate events and leaders according to His divine plan. Notably, God named Cyrus, a foreign king, as His instrument to accomplish His purposes by delivering His people from Babylonian captivity. This underscores that God can and does use whom He chooses, even those who do not acknowledge Him, to fulfill His will. Understanding His control over history reassures believers that God is providentially working for their good and His glory throughout time.
