Bad things, really bad things.
Bad things are not from God. Even if they turn out well in the end. He is never the author, cause, or bringer of evil, even if ultimately He can draw a benefit out of it.
You see God has an amazing way of redeeming seemingly unredeemed things. Whether it's people or circumstances, He can bring redemption and restoration out of any and all circumstances, but that doesn't mean He is the One who causes them all.
Don't get caught up in a mixed mentality of Christ and Judaism, Greek, Roman, or Egyptian mythology, and karma.
God = good
Darkness = bad
God = the ultimate Mr. Fix-it
Satan = the ultimate saboteur
It must be tiring to be such a good God and be accused of such bad things by mixed up kids that were taught incorrectly.
