Now, when you "suffering", what kind of suffering are you referring to? Are you referring to suffering that is inflicted upon an individual by other individuals, or are you referring to suffering due to nature, which are things that go beyond the mortals control?
If it is the former, then God let's those things go on because we have God given free will, and unfortunately, many of us use our God given free will to do atrocious things.
But, if you're referring to the latter, well, this is not in the mortals control. We cannot stop nature from doing certain things. It's just part of the post Fall and post Flood world in which we're all living in which has been tainted with sin. But when Jesus Christ returns again, He will make everything perfect again!
I'm a proud Christian
