What I see here is you altering the idea we have been discussing.
At first it was this:
In other words, a non-believer accepting Christ has been "deceived" into thinking that he has been saved by believing in Christ as his Lord and Savior.
Now, it's this:
I simply find no basis for thinking that everything Christ preached about salvation being made possible for people who come to him, believe in Him, trust in his promises, find a new life, etc. IN HIM is not the purpose of the Incarnation, the Cross, and His glorious resurrection and ascension.
