Query: Christianity explained

This is with out a doubt one of the best books written about Christianity. Packer explains in detail the religion by an in depth look at the Apositles Creed, Baptism, the Ten Commandments, and the Lord's Prayer.Each chapter is around 3 to 4 pages long, but true to his name, Packer "packs" a ton of insight into each line. You have to read this book several times to get it to sink in, but it is not a difficult theological exposition to read.For some reason this book is out of print. It is a gem if you can find one.
