Justin Taylor recently linked to some of Paul Tripp's audio recordings on paultrippministries.org, and I have been listening to a series entitled "Survival Skills for a Fallen World." Seventy mp3 downloads are available on various ways believers can apply God's Word to every day life. Tripp has some excellent insight and these recordings have already been helpful in my own life.
Paul Tripp has written several books, including Instruments in the Redeemer's Hands: People in Need of Change Helping People in Need of Change, Age of Opportunity: A Biblical Guide to Parenting Teens, A Quest for More: Living for Something Bigger than You, Whiter Than Snow: Meditations on Sin and Mercy.

I highly recommend these mp3s and books.
