I love AW Tozer's writings. I believe his views (like mine) changed over his ministry, but one thing I really respect about him his is clear love for God. It is infectious. He is one of the few 'non-Calvinistic' writers who put as much emphasis on God's attributes as Calvinists do (as did many of the non-calvinistic scholars of old).
He may have issues with the soteriological conclusions of Calvinism, but he doesn't fall into the soft peddling, people pleasing, feel good, ear tickling non-sense either. Tozer is a good example of a balanced, scholarly, pastor who clearly loved God and had a gift to communicate it.
Here is a quote from a biography of Tozer that still brings conviction and challenge:
I was preparing to go to Nyack College. Before I left there was one burning question I had in mind, and I went to Dr. Tozer and said, "Could you give me some advice concerning the problem of Calvinism versus Arminianism?"
And I'll never forget the advice he gave me. At the time I thought it was rather inconclusive and not too helpful. But I listened carefully. He said, "My son, when you get to college you're going to find that all of the boys will be gathered in a room discussing and arguing over Arminianism and Calvinism night after night after night. I'll tell you what to do, Cliff. Go to your room and meet God. At the end of four years you'll be way down the line and they'll still be where they started, because greater minds than yours have wrestled with this problem and have not come up with satisfactory conclusions. Instead, learn to know God." - Cliff Westergren
Now, I'm going to pray...
