Leave it to God 

Will not the Judge of all the earth do right?"
Genesis 18:25
 
The context of the above verse is the situation in Sodom and Gomorra. 
You can read about it in Genesis 18.
 
The question of accountability and human responsibility for sin is often debated.
 
I find Abraham’s rhetorical question very helpful in this discussion.
 
Surely the Judge of all the earth has a handle on all this
and He will do the right thing in every case.
 
We can find peace by leaving all of this to God.
 
In the meantime, lets endeavour to ‘be holy as God is holy’. [1 Peter 1:16]
