In our world we celebrate our right to life, liberty, and the pursuit of happiness.  Maybe even thinking that if we don't exert our rights that somehow we will be stepped on and taken advantage of by others.  But for the believer there is a bigger picture to see than just us.  We want to see Jesus revealed through us, the gospel shared by us, and His love to be seen from us.  We have a right not to do, even when we could do certain things.  That's the beauty of being in Christ!
Paul reminds this church in Corinth that though he could be supported by them, he chose not to.  Why?  Listen and find out.
