First, let me say that converting to Christianity - to me - sounds way too much like someone converting to some religion. Religion, and its practices are generally man made ritualistic attempts to reach the Creator. Bah! I am speaking of the act of our Creator having already reached down from heaven to offer each of us the gift of salvation to those who would simply and sincerely accept that gift.
But again, what of those innocent who suffered at the hands of the brutal regime? As I stated, each person has an inborn knowledge of the Creator. Apart from children under the age of reason, if these people chose to embrace the Creator through a personal relationship then they too would enter heaven as well. The tragic manner in which these innocent victims experienced death has no bearing on whether or not they entered heaven. Like you and me, it is what an individual personally chooses to do with the knowledge of the Creator that is the sole determining factor as to whether or not one enters eternity in heaven.
I realize that these things are not easy to grasp, but nonetheless they are the truth and are reasonable upon close examination and consideration.
Utterly disgusting.
