A Companion to "Knowing God"

J.I. Packer has recently released his book Growing in Christ. Packer says this in his introduction of his work:

This is a companion piece to my book, Knowing God, which has been used widely for group discussion.It offers a series of quick, brief outlines—“sprints” if you will—with questions and Bible passages for further study, covering the contents of the three formulae which have always been central in Christian teaching—the Creed, the Lord’s Prayer, and the Ten Commandments, plus Christian baptism.

I have read the first three chapters of the book and the introduction. I do agree with Packer that it serves as a companion to Knowing God, but also it proves to be a really good reminder of important truths after you done your own devotions. It instructs us to stand firm on the essentials and gives us standards of hills on which we might die on if we are so called. I do strongly suggest the book and look forward to finishing it myself.
