Galatians 3, belief, and habits

I usually write pretty stream of consciousness, and yes, that's code for incoherent.  the daily is meant to be quasi that, but I fear today will be even more so as I have a few things rattling around in my brain.

First, this morning we continued in Galatians, reading 3.3-6 along with Luther's comments.  This study has been quite helpful in thinking through gospel/law distinctions.  This morning Lyndsey had some great questions surrounding the strangeness of faith.  As I continue to reflect on those questions, and my own preaching, it does seem quite odd to issue an imperative to people: have faith!  I'm still not quite clear in my own mind exactly what I expect to happen.  Am I asking people to passively accept the work of the Spirit?  Am I asking them to foment faith?  

I'm quite sure I contradict myself, sometimes asking people to let go of reason or doubt or whatever, and other times I'm asking people to hang on to faith (for a whole list of reasonable reasons).  Are we holding on, or being held onto?  Or is it both?  I'm sure there's some trite analogy out there somewhere (probably involving skydiving), and odds are some model will prove helpful to me in understanding this, but I think my questions are based more out of daily existence.  Does the expectation to 'have faith' mean something different day to day, or even hour to hour?  Is it sometimes active, sometimes passive?  Sometimes holding, sometimes being held?  Or is it just always both?

Segway.

So I didn't do the Daily Office over the weekend, which is causing me to think about habits and how I view the good life.  Obviously on Sunday I read portions of the Word, engaged in prayers, sang praises, etc. corporately, along with the body at Intown.  I spent a good deal of time prior to worship in prayer for my sermon delivery and our entire worship service.  But Saturday, I didn't do much of anything.  Is there such a thing as a sabbath from Bible reading and prayer?  I'm not trying to be flippant, and I really do want to understand how to form habits well.  On the other hand though, I do think that there are 'spiritual disciplines' other than scripture reading and prayer that need to be engaged.  I think the crux of what I'm trying to process is this: I spent the whole day on Saturday having a great time with my wife, and none of it was spent in study and prayer.  Is this legitimate?*  Is it legitimate to happen weekly?  Josh, these are not rhetorical questions :).

*For any who may have stumbled across this blog, please understand I do not mean at all to suggest that if I don't have some form of devotional reading and prayer 7 days a week that I'm somehow less of a Christian.  the daily is an experiment of sorts meant to help me understand how daily liturgical practices help shape my life.  My concern is more, 'what represents a vibrant liturgical rhythm?' rather than, 'what represents a mature Christian life?'.
