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.

Dallas WillardWhat we can do with these means (our own unassisted strength) is still very small compared to what we could do in acting in union with God himself, who created and ultimately controls all other forces.
Dallas WillardThat's the secret of Jesus. You watch Jesus and you see he never did "withdraw" and then "attack." All of the time people wanted him to do it and in many ways, but he would not. Then to the body of believers he said, "This will show everyone that you are my disciples, if you love one another," but he had already said, "Love one another as I have loved you." So that's the model.
