I am currently reading, among four other books, The Pleasures of God by John Piper This is my first book to read by him and by the first chapter he quickly became a favorite.
I was in Austin this past weekend and it gave me a good chance to really dig into books that have been neglected, this one included.
In one of the chapters, he discusses a letter he wrote to a man who didn't believe God is fully sovereign and he has a quote from A.W. Tozer on the subject. If you haven't read anything by Tozer, you really should. Here is a small taste of his writings:
"Omnipotence is not a name given to the sum of all power but an attribute of a personal God whom we Christians believe to be the Father of our Lord Jesus Christ and of all who believe on Him to life eternal. The worshipping man finds this knowledge a source of wonderful strength for his inner life. His faith rises to take the great leap upward into the fellowship of Him who can do whatever He wills to do, for whom nothing is hard or difficult because he possesses power absolute."
