I would use "a gospel-centered life" as opposed to "a life of faith" for the simple reason that it more narrowly defines Who our faith is in.
I see what you're saying, bro. The faith is in Christ, if that helps. My statement left Christ out as assumed, and yours leaves faith out as assumed. But it's that "assumed" part that bit me; and of course I can only describe my own experience, not others. I was on the other side of this discussion for many years. I would have called it "the Christ-centered life" or "the godly life" probably, because "gospel centered" would have been too generic for me. I thought I knew a lot about faith; but for me it was mostly "assumed." That's why I say I lived mostly by my own sanctified (and otherwise) self-effort and resources. I finally ran up against something I couldn't handle; and it had the divine effect of driving me directly into His arms and learning what it truly means to have faith.
Anyway, I've given you I think plenty of time to elaborate on what you meant by the gospel-centerd life, and you really haven't; you just repeat it as though it somehow had magic by the word itself. The only clarification you've made is that you seem to emphasize our own ability to obey. I don't believe that is the message of the gospel. I believe the gospel has two messages: 1) that Christ took my sins on the cross; and 2) that Christ took my sin nature, the Old H. to the cross and positionally put me to death in Christ. That's the part that allows me to overcome. Not self-effort or resolve, but Christ's work. And that is only effective in me as I learn to put faith in the facts of His accomplished work.
what led you to whatever point of distinction that you have that makes one an alcoholic is either a sin issue or it isn't.
Please elaborate, or rephrase; I'm not sure what you're asking.
