A good introduction to some basic Christian disciplines. Some items like prayer, I would say MacArthur is too particular: for example, he says we shouldn't pray for mercy, grace, or peace when we already have them, but we can find prayers like that in the Bible (especially Psalms). Weird witnessing examples, but not wrong.
He promotes 17 other books and resources he's written. I received this book for free, so I consider this a form of advertising. He does promote other Bible study resources along side, from which he would receive no benefit. This book was easy to read, nothing earth shattering, but all good to contemplate.
