I just saw this – I. Howard Marshall’s New Testament Theology online for free! I need to stop buying books, there are so many on the web you can read for free.

Here’s some other great online reads:
– Pilgrims Progress, by John Bunyan
– Holiness, by JC Ryle
– Confessions, St. Augustine
– Lectures on Calvinism, by Abraham Kuyper
– Desiring God, by John Piper
