Craig Groeschel is the senior pastor of lifechurch.tv in the USA. I had the privilege of speaking at a conference with him in Chicago a few years ago. I love his heart and spirit. His church is setting an example in the free sharing of resources for the wider church.
Craig's recent article entitled 'Cool is No Longer Cool' posted on his blog is very good. It highlights the need for us to always avoid allowing style to replace substance or hype to replace the Holy Spirit.
