We normally don't require any strategy for talking about things about which we are passionate. Most of us could go on infinitum about our favorite sports team. We are not trying to land a 'knock-out punch' here, or close the sale. That's God's job. So why not simply tell others, "One thing I do know, that though I was blind, now I see."? (John 9:25). There is nothing as effective as a personal testimony!
