God is not cruel. It wasnt God that did it,be sure of it .God never does such terrible things.But He lets them happen.These things happen because Man wilfully destroys the earth .So man has to be blamed. It is wiser to trust God with the rest of your life .God loves you.He can restore everything back to you.One of His names is "Restorer". You know the God I am referring to.May God take care of you.
