Some people argue that if their really was a god then how could he let suffering to go on as well as death, the truth is that suffering and death are natural consequences of sin. Just as a pregnancy is often the product or the consequence of procreation. During the days of Moses up until the days of Jesus, Mosaic Law was often used to condemn people to death. It was inacted as law just like God instructing Adam and Eve not to eat the fruit from the tree of knowledge of Good and Evil or they would surely die. Mosaic Law was meant to confirm this among mankind that if they sin then there will be such consequences. God did not mean for us to go around killing each other for religious reasons but he wanted to instill in us that such actions committed willfully are in direct violation of his will and do carry with them as their reward very serious consequences, up to and including death and ultimately eternal seperation from God’s mercy and grace.
We were meant to make and do the best with what he has given us. And just as their are people who go with out their are also those that continually over indulge themselves in the laviciousness of this world. And Just as their are also those who were born with handicaps their was also those born with exceptional capabilities.
There are people with great handicaps that are able to excel and then there is also people born with all their facilities but are completely helpless. There are also those who were born into affluence that are a shame to their families just like there are those who go from not having anything to great wealth who make their parents very proud.
The closer we get to becoming like God the more we will be scrutinized by others because we are moving closer to the direct presence of God.
