What's the worst thing you've ever said? Now answer that question in terms of, when trying to tell someone about Jesus what is the worst thing you've ever said? I always feel inadequate or like I need to sound like a preacher or theologian. Or I back pedal thinking I've screwed it up. 

It feels like so much pressure. I also feel like I'm not the right person for the task.

Thinking about it now, how little credit I give the Holy Spirit and how much power to I give myself?

But I think in this passage, Jesus to just do the talking. Let Him take care of it from there.
