By believing. It's that simple but you didn't see it
Anyone who places their faith in Christ as their Savior, gets saved
that way. That's not just part of a Calvinist belief system. The
difference between the Calvinist and the average believer is,
the Calvinist believes he/she was chosen as part of the "Elect"
before the foundation of the world whereas, the average believer
hears the Gospel of his/her salvation and places their faith in
Christ as their Savior, without being chosen from before the
foundation of the world.
You guys believe you were
chosen, we who trust in the "Grace
Gospel" (Paul's Gospel) believe we, out of our
free-will placed
our faith in Christ.
