define "Christianity" exactly how you mean it. Simply but completely so there's no questions as to what you really mean.
And I would add one to this if you don't mind: Could you briefly describe what what you consider walking with God. Much of what you say seems to make me think monks in monastaries withdrawing from the world. I certainly don't believe we are called to withdraw from the world but to engage it through the Gospel.
I took a couple of stabs at giving intelligible answers to those questions, and they ended up being much too long (yes, longer than this!) and still unsatisfactory to me. Perhaps Jethro would like to weigh in.
My definition of "Christianity," which would scarcely be helpful to anyone else, would encompass virtually the entire spectrum of what calls itself Christianity in America as I have observed and experienced it over the past 50 or so years. Like Jethro, I too have encountered occasional individuals who genuinely seemed to me to exhibit the fruits of the spirit and to have an aura of holiness about them (but, alas, half of these saints made no claim to being Christians at all). But "Christianity" as a whole - individuals, churches, denominations, TV and radio ministries, Christian publishing, Internet forums, you name it - seems indistinguishable to me from any other segment of society except in the most superficial of ways.
Worse than that, it seems no better than any other segment of society to my non-Christian friends, literally without exception. My devout and saintly wife, who joined me here nine years ago after 53 years in the former Soviet republic of Belarus, was warned by her Baptist pastor that "Christianity" in America would bear no resemblance to anything she had previously known, and she is indeed extremely disappointed at what she has found. (I am not suggesting "Christianity" is unique to America by any means, but it is certainly rampant here.)
I think you either see all this or you don't. Millions of people apparently believe Trinity Broadcasting Network is exactly what Jesus had in mind.
If "Christianity" were truly indwelt by the Holy Spirit, this situation simply could not be the case. We may still be in the flesh, but the Holy Spirit cannot be
that weak. I am frankly puzzled that God has allowed "Christianity" to prosper and make a mockery of everything Jesus taught - but, then, I'm puzzled by lots of other things as well.
I don't believe that walking a Christian walk requires "withdrawing" from the world at all. It requires being "not conformed" to the world. "Christianity" is as conformed to the world as it could possibly get, in every sphere of life.
How do we overcome this? Probably we sacrifice a great deal more, financially and time-wise. Probably we conform our aspirations, our careers, our lifestyles, our political agendas to what Jesus actually taught - instead of conforming our "Christianity" to our aspirations, our careers, our lifestyles and our political agendas, as though what Jesus wants just magically happens to be what we want too. Probably we take Jesus' most radical teachings and warnings seriously, instead of reinterpreting them so they mesh more comfortably with our preferred lifestyles. Mark 10:17-27, Matthew 7:21-23, James 1:27? Nah, none of that really applies to us - at least in any way that would seriously interfere with our pursuit of the American Dream.
In my own case, I do find withdrawing from the world to some extent (think "urban hermit") to be helpful. I have no TV service, my cell phone is a Jitterbug from the Dark Ages, I do not participate on social media at all, I am largely disengaged from the daily news, I have cut back on "Christian" talk radio and even on my book purchases - and, yes, I do believe this has all been beneficial to my Christian walk. I can see at least some of the fruits of the spirit in myself, at least compared to the me of 50 or 25 years ago, and others have said they see them - and yet, the very acts of the flesh Paul describes in Galatians 5 (with the possible exception of witchcraft) are still present to a truly disturbing degree. I do find this extremely puzzling, to the degree that I do sometimes wonder if we have all completely misunderstood Jesus or even join my friends in wondering if Christianity is uniquely true at all. So I make no claim to being a particularly good specimen of true Christianity, merely to having the virtue of not being a card-carrying "Christian."
But I'm not here to prescribe to anyone else. I am merely sharing what I have observed, because I have viewed my mission for the past ten years or so as being God's thorn in the side to "Christianity." Because Certain Moderators and Participants clearly do not welcome my participation, I am now going to move on and leave this fertile mission field to Jethro. If you see any more posts by me, you will know I have broken a sacred vow to myself.
