This particular question is what the unbelievers use in trapping most Christians saying
If there truly is a God, why then is there suffering in our world.
Why doesn't it end?
Why do good people die, day in, day out.
The answer, this world as we know it, is under the control of the evil one. And sometimes things happen that is beyond our understanding which further makes it questionable if God truly is for us.
But what can we do in such situations.
We can go back to our scriptures and see what God tells us there.
He says All things work together for good of those that trust in the Lord and we should count every thing as gain and must firmly believe that even though we might see trials we will eventually overcome
