You will not want to miss this. If you have never read it — and even if you have — hie thee over to Christian Audio to download J. I. Packer's Knowing God. It is their free audiobook of the month.
I was saved in 1973, the year this book came out. A friend gave it to me in 1975, and I read it right away. It was very helpful and encouraging. Packer wrote of some of the deeper truths of theology — of God — but did it in a winsome, accessible way.
Wherever you are in your growth in Christ, I'm confident you'll find this an encouraging, helpful book.
