In 2007 I spent a brief period of time at L’Abri in Massachusetts. While there, I was introduced to the teaching of Tim Keller, pastor at Redeemer Presbyterian in NYC. His teachings on grace, which I was there to study, changed my life. I have nothing but admiration for the work he has done and aspire to be like him. The Wall Street Journal has done a profile of him that is quite interesting. Stop on by their website and check it out.
