How to begin a spiritual life?

I am starting to read Eugene Peterson's The Wisdom of Each Other, and tonight I saw this:

..the phrasing is askew: you don't begin the spiritual life, the Holy Spirit does. ...

So the question is not primarily "What do I do?" but rather "What has the Holy Spirit been doing in me all these years of my noncooperation and what is He doing still?"

from page 32

See why it struck me? It was something I was writing about the other day, something I heard in church the other week. It's not what I do, but what the Spirit is doing in me, and I'm not resisting.
