God knows everything...not just what could happen but what will actually happen (tons of scripture back that up).
How does God know everything? Because He is the source of everything (tons of scripture back that up) since He has predestined everything (tons of scripture back that up) and governs everything (tons of scripture back that up).
God even causes evil (God is the source of everything and evil is a thing) to come about, yet he is not evil (tons of scripture back that up) and does no evil (tons of scripture back that up) despite causing it.
The 1689 London Baptist Confession of Faith says it best:
"God has decreed all things that occur, and this he has done in himself, from all eternity, by the perfectly wise and holy counsel of his own will, freely and unchangeably.
Yet he has done this in such a way that God is neither the author of sin, nor does he share with anyone in sinning, nor does this violate the will of the creature, nor is the free working or contingency of second causes taken away but rather established."
