Christian but sane?

Well, it seemed like a good ID to start with! So much of what is claimed to be Christian doesn't sound very sane. Or very Christian.
But then are bloggers sane? Don't know. Never tried it before.
I've believed in Jesus Christ for as long as I can remember, though my view of him has changed. Evangelicals would say you 'become a Christian' at some particular moment - a definable shift of focus in the way you see everything. I've had moments of 'seen the light!' But also many moments of 'what was that again?'
It's a bit like looking at your hand in front of your face, through the right eye only, then looking at it only through the left. The hand remains the same, in the same place. But it seems to shift, because your focus has shifted.
So sometimes I look at life and it's quite obviously all pain and misery, war, babies dying, people starving. And how has any of that changed, because of Jesus dying on the cross? Just one more dead man, right?
Then, the focus shifts again. One man spent his whole life doing exactly what his God-given purpose was: loved every single person he came across, got enraged with hypocrisy, avoided the professionally pious, gave up his own comfort, walked miles, spent time with the sad, sick and deranged ... and actually, yes, it does help that he did that.
It's only one life. But it helps me because I've only got to live one life - not sort out the world or live anyone else's life and if I look at how Jesus lived his, it actually is possible to live a life of goodness in a world that doesn't value it, or me for wanting it.
Goodness, integrity, compassion. Not an abstract concept or wishful ideal. Not a waste of time but powerful stuff, backed by a life.
If one nuclear power explosion, like Chernobyl, can pollute a whole area for generations, then an explosion of sheer purity, like Jesus' life, can surely do the opposite?
I read about the long-term consequences of crime - how one reckless violent act can pollute a victim's whole life, or a whole community's life, for generations afterwards. But how about one selfless, deliberate act of love, for strangers who would thank him for it by turning his name into a swear word and his crucifyingly painful humiliating death into a running joke for 20 centuries afterwards?
Jesus is powerful stuff, to my mind. A catalyst for change in a person's whole focus.
So how come the main reaction to Christians - his followers - is 'boring'?
We're either getting a lot wrong, or the good stuff just doesn't get seen.
