My pal has been meaning to get an Ipod and wants to get it charged up with a few talks so he can listen to them on his business travels. There is a verse in Romans that says 'faith comes by hearing' and it's true. We will over time become what we listen to. Like any food, what you need is a plentiful and balanced diet and then over time you will grow up strong.
My pod is loaded with talks and I have listened to all sorts of people speak down the years. I sat under the wonderful preaching of John Irvine for over a decade who probably shaped my heart more than anyone else. If I am driving or getting the tube or walking in the park I scroll down my podcasts and decide to listen to.... [Of these people I have down the years listened to some more than others and they have a star by them]:
