Au contraire. Those facts all support salvation ... as Theophilus seemed to say. If those facts are not accurate, salvation is unnecessary anyway.
Many cold rational people *have* come to salvation after examining the facts or engaging in true philosophizing.
CS Lewis (once an atheist), Francis Schaeffer (once an agnostic), Don Bierle, etc...
But it only works if the heart is willing as well. If it is not, the lack of stumbling blocks in someone's path won't change it. Christ crucified is his own stumbling block to those who do not seek truth.
This sounds vagely Calvanist to me. Predetermined to be saved?
C.S. Lewis was a theistic evolutionist.
