A.W.Tozer is an oldie but a goodie. I've read him for many years and have found him useful to refresh my memory on the basic tenets of the Christian faith. I went overseas and took this slim volume with me to have as a guide and touchstone in my travels.
His chapters give an indication of the content.'How important is creed?', 'The inadequacy of instant Christianity','The freedom of the will','Why the Holy Spirit is given'...There are twenty chapters in all and in his careful and well thought out way Tozer is a great read.
I appreciate this book because it helps me keep grounded in the basics, the cornerstones of my faith and helps to give perspective to a lot of issues surrounding my spiritual journey in a modern world.
