Are the faith-alone Christians right that if we are saved, we won't be tempted, and if tempted we aren't saved?

No. In Christian teaching, a request for forgiveness involves genuine repentance. If you steal something with the intention of asking forgiveness for it so that you can get away with it, then you are not genuinely repentant.

You might fool some people, but you will not fool God.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
