Mathematics

You know the basic rules of maths. 2+2=4 You never question that.
When somebody asks you a maths question you don't know, do you suddenly doubt the very existence of maths? No. You simply accept that you don't know maths well enough to know the answer.
A 5 year old gets that they just aren't able to do quadratic equations. So why can't we accept that we aren't wise enough to comprehend all of God.
We know that God is good but when somebody throws an earthquake or cancer or floods into the equation, suddenly we start calling the basic rules into question.
Why do we do this?
God IS good and 2+2=4
That stuff doesn't change.
