You're quoting the hypothetical "easy believer" who says that claiming Christ is "all that's necessary" for salvation. But the claim itself is not "all that's necessary." Read the Epistle of James who explains this matter at length.
Yes, we can affirm that Faith is necessary, that Faith saves, etc., but WHAT DO WE MEAN BY "FAITH?"
Most Christians, like James, know the truth of the slogan "Talk is cheap." For a person to
claim to have saving "Faith" in Christ
while making no effort to live like it...is not to have real Faith, period. It's what some people have called "Easy Believism."
No one has disputed that fact on this thread and certainly not yours truly.
Do you have anything to add that's actually on-topic?
No one has suggested that, either. The question was about the
meaning of the term, not whether or not we favor it, who uses it, or whether you or I might ever use it in conversation ourselves.
