Here are some resources that I have found incredibly useful over the years. There is everything from online resources, Bible software, and other blogs. I hope you find them enjoying and edifying!
Monergism Free E-Books
Mongerism is an incredible online resource regarding reformed theology and other aspects of the Christian life. The above-posted link is to a page with over 600 free ebooks on the Christian life from various authors. Enjoy! *Update* Monergism now has an eBook Library app for iOS and Android! Check it out!
Bible Gateway
Bible Gateway is a great online resource for looking up Scripture. It has almost all if not every, translation of the Bible available.
Desiring God
The ministry’s website that John Piper started is filled with incredible resources. Articles, podcasts, and most of John Piper’s sermons are here at your fingertips, covering a massive range of topics that deal with the Christian life.
Challies.com
The home of Tim Challies’ blog, who is probably one of the preeminent Christian bloggers on the planet. He has a vast library of articles on nearly every subject.
Blue Letter Bible
Blue Letter Bible is a great online resource with commentaries and other things for the person doing some serious Biblical research. It is a great place to start digging deeper into Scripture, helping one to understand more of not only what is said, but the reasoning behind it.
Logos Bible Software
Logos Bible Software is probably one of if not the most powerful Bible software available. I’ll admit, it is a little pricey but it is entirely worth it. There are other Bible software programs out there, such as Accordance and Olive Tree, all with pros and cons and different price points. I encourage you to try them all out and find the one that works best for you.
Crossway Articles
Crossway has some of the best articles on everything from books to theology and so much more. I have greatly benefited from many of the articles here, and I am sure you will, too.
