"The Lord Almighty has sworn, 'Surely, as I have planned, so it will be, and as I have purposed, so it will stand.'" NIV translation
If God says it, then, it is going to happen and He has His purposes for all things. The Babylon that we saw judged had not even came to power at the time that this prophecy was delivered but it was going to come to fulfill God's purpose. In the same way, God has a plan and a purpose for His people as a group and also as individuals. He has made plans for all of us and they will be fulfilled.
