More recent book purchases:

-Now, that's a good question! by RC Sproul. Sproul answers questions ranging from "Do you believe that God has audibly spoken to anyone since the apostolic age?" to "Should Christians use credit cards?"
-The Holiness of God by RC Sproul. Heard some good things about this...
-The Ragamuffin Gospel by Brennan Manning. Recommended by my small group leader my freshman year (Kenny Kang), but I never got around to reading it.
