/what/ -...

We must do what Christ did.
.
We must make mistakes.
.
We must live out our own vision of life.
.

And there will be no error. If you avoid error you do not live; in a sense even it may be said that every life is a mistake, for no one has found the truth.
.
When we live like this we know Christ as a brother, and God indeed becomes man.
.
This sounds like a terrible blasphemy, but not so.
.
For then only can we understand Christ as he would want to be understood, as a fellow man; then only does God become man in ourselves.

Wisdom begins only when one takes things as they are; otherwise we get nowhere, we simply become inflated balloons with no feet on the earth.
.
So it is a healing attitude when one can agree with the facts as they are; only then can we live in our body on this earth, only then can we thrive.
