Christianity seems not to be enough

I have observed over several years, that in order for Christianity to be effective in a life, it needs to be built open solid formative years experience. So, for instance, if a person in their twenties makes a faith commitment they will find their faith a viable and rewarding experience only if they are a fairly well rounded person. If, on the other hand, they have had a screwed up childhood and then make a faith commitment, they will always be slightly nutty, extreme, or on the fringe of church. Although this later groups faith is often the most real thing in their life, it rarely produces the sort of holistic results which would set them free. It seems that the way we do Christianity has no power to heal deep seated psychological trauma, and so we use Christian psychologists instead. Which kind of works, gives people an airier cage, but doesn't set them free.

It has always seemed to me that people should have the right to be free, to balls things up them selves, and that that principle is one enshrined in scripture. And yet we know that a screwed up childhood means that a person is so damaged that they may never know what it is like to even start being themselves. They will simply hate who they are.

This principle of freedom seems so fundamental to me that i have spent many years on this one question, can God set people free?
And i have concluded that, yes, he can, it's all there in the bible. But its more about understanding than knowing. And that is hard to get across.
