Dave 1969 - Why bad one�s prosper and why innocent children suffer and why you are sick. For that all,
First of all is the proof that this world is not perfect and there is another world where these things will not happen. In this world it is happening because God has given few things in human control.
Secondly because God knew all this will happen and that is the reason he clearly said that this world is just a test. Test of the people who have Health, Wealth, prosperity and all or most of the worldly blessings. Their test is that how they use that for the benefit of others. With health, do they help the weaker or they attack the weaker because they know they are stronger. With wealth, do they use that to help others or put that in the higher interest account and make poor even poorer.
As for the people who have not got these things, God asks them to be PATIENT. And that�s all and God says that I am with the one who shows patience. Decease in this world shreds your sins because that is when you remember God. Innocent children, they will be rewarded in hereafter anyway. If we have control on any matter out of this, we should try to be good
