The Discipleship Series is a series of lessons, all in this one book, about the fundamentals of Christianity—specifically, Pentecostal belief. Although it’s only 90-odd pages, it’s not a quick read. There is some real meat in here.The strength of The Discipleship Series is that it is written in conversational English, using extensive Bible quotations to back up its arguments. It’s not an incomprehensible theological treatise. It’s simple , just like the gospel is meant to be, and reflects his view that “the decisive qualifications for profitable Bible study are spiritual rather than intellectual.”There is nothing new here, but that’s the point: it’s an explanation of the central views of Christianity (albeit from a Pentecostal viewpoint). Sande’s not trying to lead the church into a new revelation, but to solidify our understanding of our faith, and reignite (or ignite) our passion for worship and fellowship (I found those sections particularly inspiring). Importantly, I didn’t find any areas where it misrepresented or twisted Christian belief (which is more than I can say for some ‘Christian’ books I’ve read).The weakness of the book is that while it is a solid discussion of belief, it’s not really clear who it is aimed at: the non-believer, the new believer or the Christian who is more established in their faith. There are also occasional typos or misused words, and some formatting bugs in the ebook, but these do not distract from the central message. Overall, this is a very readable work which would make an excellent Bible study for young adults, new Christians, or those who would like to understand evangelical or Pentecostal Christianity better. Thanks to the author for providing a free ebook for review.
