One the best-resourced websites I know of is the Gospel Coalition, which has hundreds of free sermon downloads you can listen to....people like John Piper, DA Carson, Mark Driscoll and Tim Keller. Here is a weblink to their resource page:

In Russia

Finally, here is a quick update of our time in Moscow. I am taking three hours of language a day and involved with a small church who have a lot of young people passionate about seeing the work of God in their lives. It's still pretty cold here, but fortunately public transportation is readily accessible almost everywhere. Here are some pics of our place and surroundings.
