Target the 88%

The video at this link, of Skye Jethani talking about the importance of targeting people's 88%--the portion of their time every day, every week that isn't discretionary--is absolutely dead-on. Too much of what we pastors and preachers speak to in our churches is aimed at people's 12%, the time that isn't already spoken for by jobs, commutes, family responsibilities, etc. How much more effective would pastors and churches be if we equipped people in the things they do with the majority of their lives?
