Why "mysterious ways" don't matter.

[Mudhammam]

It would make a better argument for objective moral values.

1. If God exists, objective moral values exist
2. God exists
3. Therefore objective moral values exist.

Now, if you'll excuse me, I'm going to go wash my hands.

Why would God's existence imply that moral values are objective?

God could be like Yahweh, in which case he would appear to embody both qualities that human beings typically consider good and evil. But what grants him authority over what we might consider a rational ground for moral value? Because he says so? That argument appears to me to be nothing but sophistry, plain and simple.
