Why does God allow bad things to happen to us?

In a man’s life are both good and bad. And good things and bad things. And joy and suffering.
God let me go through all of us to educate and train in order to better lives. The believer must know that: nothing bad happens on the ground without God knowing.
And if he knows, that means allowed it for a purpose, and that purpose can not be understood by us now.
