Admittedly, no systematic theology is perfect. That takes a load of pressure off of every sincere Bible student. Not one of us will ever have all of his or her doctrines correct. C. I. Scofield wrote that there will always exist a measure of false teaching in true, orthodox Christianity, due to our fallen nature and our design as finite creatures.
I was once convinced that Calvinism was right because people showed me a lot of proof texts to propagate this theology. I had read Chosen by God by R. C. Sproul and concluded that he, too, was correct. How could I have missed out on this teaching for so long? I will never forget what affect Sproul’s book had on my heart. How could God have chosen me and not others? Moreover, why would God have chosen me and not others?
