Origins of Life
It appears that the problem of evil is not just a particular argument; however, there could be a cluster of arguments that relates to certain concerns and have an identifiable structure. By definition moral evil occurs when human beings deliberately harm each other. Where they sometimes kill, rape, slander or steal from each other, whereas natural evil is where the causes of the problems are beyond our control such as deadly hurricanes, tornadoes, and earthquakes.
The reason as to why there is sin among mankind is because God allowed mankind to have a free will, this is where the argument that if god exist surely he would prevent for this evil to occur. And when we look at the issues of natural evil it is distinct from moral evil because it cannot be attributed to the free will of human beings. The internal consistency is to avoid self-contradiction the law is expressed in precepts. Prohibitions or dictates it is external and on the internal side man is born with an inmate knowledge of God.
In meeting the religious/emotional challenge we must appeal to the truth revealed by God in Scripture. Even for the believing Christian there is no greater test than that of the God who loves us so permits us to suffer, even at times where it could be in some excruciating ways. Thinking on the fact that we have a free will to believe as well as not believe in that of what the word of god teaches, I can see where a dispute can be but without attacking god himself no. The bible teaches us “there is a way that seemeth right unto a man, but the end thereof are the ways of death” (Proverbs 14:12).
