A few posts ago, you pointed out that Wesley saw justification as the door to the house of Christian life. I know far too many Baptists who think of salvation as an airlock. They get in through baptism and saying a prayer, and that protects them from the harmful atmosphere outside. But, the airlock is a very tiny room and you stand in there until death, when the door on the other side opens to admit them to heaven. Unfortunately, I know far too many Methodists who think the same thing.
And of course, if you accidently use the word "work" or "effort" when talking about sanctification, they jump on that and shout "HA! I knew you guys believed in works-based salvation!"
