Just to flesh out a bit what I'm saying, I believe Jesus was talking about and hoping eventually to achieve a COMPLETE TRANSFORMATION in the lives of His followers through TOTAL COMMITMENT to His message. Consider:
"No one who puts his hand to the plow and looks back is fit for the kingdom of God.” Luke 9:62.
"Let the dead bury their own dead, but you go and proclaim the kingdom of God." Luke 9:60.
"If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple." Luke 14:26.
"If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me." Matthew 19:21.
“Therefore I tell you, do not be anxious about your life, what you will eat, nor about your body, what you will put on. … Instead, seek His kingdom, and these things will be added to you." Luke 12:22-31.
I don't think He was talking about "sorta kinda" fitting His message into the comfortable, worldy lives we all want to live. I don't think He was talking about "believing the right doctrines" and arguing endlessly with others. I don't think He was talking about what "Christianity" looks like today AT ALL.
The above verses are all, of course, conveniently explained away in "Christianity." Jesus didn't really mean THAT. He knew THAT would be too demanding. Those verses are just hyperbole, aspirational and inspirational, but NOT what He was REALLY expecting.
In what I call pretend Christianity, it's all about believing or at least pretending to believe the "right" things. It's about slavishly reading the Bible, or at least saying you do. It's about fitting into some sort of undemanding Christian community and congratulating ourselves that we're not like "them" (a category that not only includes atheists and Hindus but even other species of Christians). It's about having at least a thin "Christian" veneer on entirely worldy lives that really look only superficially different from what they'd look like if we were greedy, ambitious atheists.
This is what MY life looks like, too, mind you, I'm not saying Jesus is happy with me either. I'm just saying I'm not going to continue to play the game of pretending that I think this is OK or what Jesus was talking about. I think "Christianity" is pretty much 180 degrees from what He was talking about.
And why are things this way? Well, as I said, it's puzzling enough to make me question whether there is any reality to any of it. On the other hand, I have seen enough transformative effects of the Holy Spirit in my own life to think - not "know" :) - that there must be. Probably it comes down to the doubt that many Christians like to pretend they don't have. Do any of us take the above verses seriously? If we did, would our lives look anything like they actually do? Isn't doubt the reason we hedge our bets and keep at least one foot planted firmly in the world. What other explanation could there be?
If we can't be the disciples Jesus hoped to have, at least we can stop pretending and start trying to move in that direction.
