Advertising

So, as I'm sitting here doing homework, I'm listening to a teaching by JR Woodward on the Gospel of Mark. It's the first of what is supposed to be a killer series. This first teaching, he is talking much about advertising. He's talking about how we have things that we don't need. What do we need to be doing? Do we need to be getting rid of our stuff? Do we need to prepare ourselves and guard against these advertisements. I'm feeling slightly convicted and thinking about things I have. Should I have them? Should I worry about what I purchase? I think these are some stark possibilities. Just thoughts my friends....Just thoughts.
