Through his books and sermons and through his instruction of one of the most influential professors in my life, this man, at least as much as any man and more than most, has helped me to know God. Of particular impact on me were his works, Knowing God, Growing in Christ, Concise Theology, and perhaps most of all, Evangelism and the Sovereignty of God. If you don't yet know J.I. Packer, you really should get to know him. I can't wait to read his latest book, which he talks about here.
