Omniscient -- all knowing. In God's case, he knows everything about everything and holds on to all of it always. (Unlike us, who have something like a mental filing cabinet, where we pull out information we do know, when we need it, but it's not there at any given moment. It gets put back for further use when done. Or, in my case, sometimes flies out of the brain all together. lol) Fits perfectly with foreseen because he sees and knows everything always.
Sovereign -- the supreme ruler. Nothing happens -- ever -- without his say-so, and what he wants to happen happens every single time. Actually, that's technically not it, because he's outside of time, so it happens as he wants always.
During creation God created fish. Out of those fish came more and more fish. And the fish lived their fishy lives. If fish had a collective memory, they would probably remember the year when the whole earth was underwater. Then again, I don't think they have collective memories. But that was a weird year for fish. Mostly they go where they go to eat or mate, and marine biologists have determined sometimes that's thousands of miles for a particular meal.
But one day, one huge fish was under a ship when sailors threw a man over during a storm, and that fish swallowed that man. Then the fish went about its fishy business for three days, found something interesting near land, got a belly ache, and vomited out that man. Jonah landed on shore right in front of Nineveh, right at that moment when he decided he'd do what God wanted him to do.
Tell me you don't think God predestined that.
THAT is the full sovereignty of God!
There is no either/or. There is God. He is both plus so much more!
