Get reading!

If you want to know God better and grow to maturity in your faith, you must  read (and/or listen) to good books (and especially the Bible).
But there are hundreds of thousands of Christian books out there. Some are great, others are thoroughly misleading. How do you choose?
Well, having a bookseller that only stocks reliable books is a great help. To my knowledge there are just two of these: The Good Book Company and 10ofThose.
St Peter's has set up a linked website to 10ofThose.com, where you'll find some of my personal recommendations. Not only that, but they're very good value, St Peter's gets 3% commission, and no, you don't have to buy 10 of them!!

But back to reading. Where do you start?
First, you need to hear God himself speaking to you in the Bible. So you need a good translation - the English Standard Version is my personal preference: it's a good translation, it's clear and precise. Next best would be the New International Version - not quite as precise, and often misses important linking words ('for', 'because', 'so that' etc.).
But don't just buy a 'plain' one, get one with cross-references which really help you to explore topics further, and to see, for example, where the Old Testament is quoted in the New.
Better still, get the ESV Study Bible (this is much better than the NIV equivalent). Here you'll find great introductory articles, maps, footnotes which begin to explain the text and access to the online Study Bible. If you can possibly afford it, get the hardback because it will last much longer!

As for other books, take a look at 10ofthose and see what I've recommended!
