Time to get out of the salt shaker?

I heard a comment today that struck a chord with me.  Phrased as a questions something like-Is it time for you to get out of the shaker and spread your salt around in the world?  We are cautioned to study the Word and grow in a personal relationship with Christ, but Paul also tells us to move on from baby food to real meat.  I think the salt shaker comment aligns with this view too.  Some Christians seem content with a very narrow lifestyle and seem to only focus on internal growth.  Or a narrow definition of what living out the Great Commission means.  But every job we do can be to God's glory.  Every single workplace can be the Mission Field, not just those with different languages, halfway around the world.  We are told to treat our jobs like God is our employer. (Colossians 3:23)  Boy, how I struggle with that some days!
