When the will is enslaved to a desire, it will in turn enslave the mind.

Education (the institution) has now adopted values, attitudes, and practices that make any rigorous understanding of the human self and life impossible.

What Paul is clearly saying is that if anyone is worthy of being saved, they will be saved. At that point many Christians get very anxious, saying that absolutely no one is worthy of being saved. The implication of that is that a person can be almost totally good, but miss the message about Jesus, and be sent to hell. What kind of a God would do that? I am not going to stand in the way of anyone whom God wants to save. I am not going to say 'he can't save them.' I am happy for God to save anyone he wants in any way he can. It is possible for someone who does not know Jesus to be saved.

Apart from Christian spiritual formation as described here, I believe there is little value in claiming exclusiveness for the Christian way.
