This is simply the classic "if man is not in control and leading God, then God causes evil" red herring. You are free to accept the claims of Islam as being potentially equally true to those of Christianity. That is your choice. I suppose if one's faith is blind, then why not? With no foundation for faith, then Islam really shouldn't be any better or worse than any other faith. We, of course, do not look at it that way because we do have a foundation for our faith.
As I noted in my last post, God uses the evil of others for the greater good of His plan. I know you probably think that all the events that had to come together for Jesus to be able to sacrifice Himself for us were probably just a huge collection of accidents, a huge collection of individual free will choices that by chance just happened to come together so that today we may be saved. I, of course, say that the whole thing was orchestrated by God because He loves us and would not leave anything to chance when it came to the salvation of His children. I don't believe in luck, but I know that many do, and even base their faiths on it.
You can't have it both ways, FK. We can't be living under a delusion of freedom if everything we do is God's will. Worse, we can't be condmened for something that was preordained before we even existed.
If we are simply actors in God's divine soap opera, then we are simply acting out the script and our roles are not real us, nor are our words "our" words.
The fact that God in the Bible holds us repsonsible for our acts and words means that they are not his but ours. If they are in harmony with God's will, they are good. If they are contrary to God's will they are evil. That can be true only if they are our choices, not God's.
